Like the last map, Map Eight goes between two towns (Walpole and Denmark) at either end of the map, and only two huts in between - there are no other services. What you will see is the magnificent karri and tingle trees next to the Frankland River, the beautiful Greens Pool on the Coast as well as varied forests and farmland.

To get the full ride gpx or the ride route summary, select the "Route Sheets" tab above, and click on the download buttons for each.

Map 8 is full of contrasts - the first section will take you passed some truly amazing tingle and karri trees, and the ride along the Frankland River near Monastery Landing and Sappers Bridge is very special (but a bit tough). The last section from Jinung hut is spectacular as well - the hut is under the karri trees, the ride goes passed Greens Pool, near Waterfall Beach, and along the Coast on the WOW Trail with really great views. But there are some pretty average sections in there as well. The section of Middle/Boronia/Break/Nornalup/Mt Lindsay Rds is about 50 km of flat, open, gravel or sand road with no shade. In Summer it is very hot and the sand sections are very sandy and very tough to ride. And then in Winter, it can flood! The 2km of corrugated road from Green Pool towards Lights Beach is dreadful too - made worse by the fact that this is a beach access road, so you have to share the road with cars. An alternative to Map 8 is the Denmark Nornalup Heritage Trail - I have tracked it from Walpole to Gully Rd on the Munda Biddi, then on to Denmark on the old railway line. It is flatter and easier, and passes Bow Bridge, where you can get food. But it misses some of the spectacular scenery, and has 10 km on the highway. However it is possible to link sections of the two together. See the separate map for further info, and the pros and cons of each route.

Here is my two minute Map 8 highlights video. We started in Walpole, and rode under the Tingle trees and next to the Frankland River. The middle section is a lot of gravel road, but then the Trail goes to Jinung Beigabup hut, which is spectacular, as is the coast near Greens Pool and Lights Beach. It finishs in Denmark. My wife and I rode it in early January 2016.

Walpole lies very close to the northern point of the 100-hectare Walpole Inlet, from which it takes its name. The average rainfall is 1200mm, and population is about 500. The town has a small general store, and a couple of accommodation and eating options. Basic bike spares are available from the Hardware store on Vista St. If you need assistance with transfers along the Trail, Naturally Walpole Track and Trail Transfers may be able to help. Lee and Karen are fully insured and licensed operators providing transport and support needs in and around the Walpole region. Contact them on 0429 784 924.

In Walpole, the route didn't go through town as indicated on Map 7 and 8, even though I have the latest edition of map. It is no big deal - the markers are clear, so follow them. The visitor centre is located in a pioneer cottage in Pioneer Park, just opposite the main street. The Trail passes behind the visitor centre. There are toilets, picnic tables etc at Pioneer Park, and shops are across the highway. The Visitors Centre carries Munda Biddi maps, dehydrated food and gas bottles. See:

Coalmine Beach: It seems that an early settler found what he thought was coal in a cave on the banks of the Inlet. Subsequent exploration found the little amount that was found to be of poor grade and uneconomic to mine. Coalmine Beach is on the south shore of the beautiful Nornalup Inlet. The Knoll is a peninsula, which divides Nornalup and Walpole Inlets and is accessible by the one-way sealed Knoll Scenic Drive. This drive follows the perimeter of the Knoll with views of Walpole and Nornalup inlets. It is just off the edge of the Munda Biddi map as the trail joins the Coalmine Beach road. The loop is around a couple of kilometres long.

Nornalup, on the South Coast Highway, started as a railhead and farming settlement nestled on the Frankland River. It has no facilities such as shops. Even the water at the public toilets is signed as not for consumption.The Munda Biddi passes near, but not through, Nornalup.

The Nornalup estuary is unique among south coast estuaries in that its sand bar never closes. Consequently, the estuary is tidal, and the continual flushing by ocean waters means the inlets are a healthy environment for marine life. Fresh water feeds into the inlets from the Frankland, Deep and Walpole Rivers all year around, although 80% of the flow comes in the wettest months of June to October.

The first 10 km after Walpole (now map 8) takes you around the Nornalup Inlet and then parallel to the South Coastal Highway. The Giant Tingle tree (indicated on the map) is about 2km up Gully Rd - but it is a one way road and you would need to ride against the flow, uphill, to get to it. More than 100 people have fitted inside it's burnt out base! There are many other tingle trees to come, but you may wish to make the diversion. If so, ride up Gully road with caution.

The Munda Biddi then follows the Frankland River. All those contour lines close together means the hills are extremely steep, but as we follow the river, we avoid the worst of it. But there are still lots of hills - the map profile doesn't show what a roller coaster ride it is. It is worth it though - there are views down to the Frankland River, framed by towering tingle and karri trees.

Monastery Landing is landing on the Frankland River's edge, with picnic table and chairs but no other facilities. It was never the site of a monastery. One story is the name came from a remark made by a surveyor's assistant who said that the area was "as quiet as a monastery". People who heard him thought that there was a church built up the river and the name has stuck. Others contend Pierre Bellenger named the spot, saying that if in France a Monastery would have been built on such an ideal location. It is the perfect spot to rest for a few minutes.

Sappers Bridge was re-built October 1982 for the National Parks Authority by sappers from 22nd Construction Squadron RAE following flood damage January 1982. There is a small rapids near it. Cars cannot cross here - they must turn back.

The Tingle tree, a species of eucalypt, is one of the tallest trees in the world and can measure up to twenty metres around the base, grow to a height of seventy five metres and can live up to four hundred years old. They often have shallow root systems and grow a large buttresses base. Climate change over millions of years has caused their distribution to shrink, and now they are found mainly in the Walpole-Nornalup National Park and a few places close by, in an area of about 6,000 hectares. There are in fact three varieties of tingle tree; the red, the yellow and the Rates. This was discovered by the first District Forester of Walpole, John Rates, who was sadly killed by a falling tree limb in 1969, and one variety was named after him.

The Valley of the Giants tree top walk is about 500m from the Munda Biddi route and was marked when I was last there in Jan 2018. It is well worth the detour. The Tree Top Walk is a 600 metres loop, up to 40 metres high above the tingle and karri trees. It is on a series of lightweight steel trusses built on steel pylons to form a secure walkway, so there is no climbing involved. The walkway does move around a little, which can put off some visitors. This marvellous feat of engineering was opened in 1996 and cost $1.825 million. It cost us $21 per adult in Jan 2018. There is also the Ancient Empires walk, which is free to do. There is a small shop selling souvenirs, ice creams, cold drinks etc, and proper toilets. It can be busy during the holiday period, often with international visitors who come to marvel at the magnificent trees.

This is what our trip to the Tree Top walk looked like in 2018:

Bow Bridge began as a timber milling and farming settlement on the banks of the Bow River which flows into the Irwin Inlet. On the corner of South Coast Highway and Valley of the Giants Road, the Bow Bridge Roadhouse serves as a convenient Post Office, Grocery Store, Video Store, Cafè and fuel station. Since its establishment some fifty years ago, "The Bow" has become a one-stop-shop, providing everything you might need while exploring the area. To get from the Munda Biddi  to Bow Bridge-
0.0 km At Middle Rd, when heading North on the Trail, the Munda Biddi turns right on to Trent Rd. Follow Middle Rd to the left (all three are sign posted)
1.6 km turn left into an unnamed sealed road (Valley of the Giants Road)
3.8 km At T junction with the highway, Bow Bridge is on your left.

Booner Mundak (means "wild place" or "the bush" in the local language) hut is my least favourite hut - only because it is in the middle of the long boring stretch of gravel and sand road in the middle of this map. I have ridden this section only once - the second time I arranged a lift from Middle Road to Mount Lindesay Rd. When I rode it in early Spring, the sand on Middle Rd was reasonably compact and not too bad, but riders in Summer have complained that it is impossible to ride. Middle Rd is about 19km and has many long patches of sand. Next time, I will most probably ride from Gully road into Nornalup and on to Denmark via the Denmark Nornalup Heritage trail - see here for details. I had intermittent phone signal at this hut. For more on the hut and campsite, see here.

Here is a break down of the visitors who signed the log at Booner Mundak in 2017. Thank you John Bailey for making this presentation. Unfortunately, numbers are very low.


Middle/Boronia/Nornalup/Break Rds are, as I have already said, flat, open, gravel or sand roads with no shade. In Summer it can be very hot and the sand sections (mainly Middle Road) are very sandy and very, very hard to ride. Can you see all the streams on the maps in this section? Combined with the many flat sections, it means in Winter, these streams can flood the roads! They are usually not deep (50cm), but the Trail can be flooded for hundreds of metres. The exception is the Kent River, which flooded in 2013, cutting the Trail in half with a major torrent, and meaning major diversions. But the storms that caused this were exceptional, causing loss of power in Walpole and Denmark for days, and they made the news in Perth.

If you get to Harewood Road and are getting tired, you can use it as a short cut to the hut.  From Break Road to Champion Lane along Harewood Road is 6.2 km. Champion Lane is signposted and Harewood Road is signposted at Break Road. Harewood Road is an undulating gravel road that is initially a single lane (near Break Rd) but becomes double lane near a Champion Lane.

Mount Lindesay is only 2km from the Munda Biddi Trail, along Nutcracker Road. It is well sign posted. The 385 metre high feature is an "island" of ecology" - scientists have established that the jarrah scrub, mallee heath, and other plants that grow in and around the granite outcrops on Mount Lindesay are distinct from other areas, and some are found no where else in the world. The 10 km round trip first plunges from the information hut down to cross the Denmark River, then rises up a moderately difficult climb. You should allow 4 hours to do the return walk - I did it in 2.5 hours, but I had driven there, and so was not tired from riding there. Here is a short video of the climb:

Jinung Beigabup means "Looking towards Mt Lindesay" in the local Noongar language. Mount Lindesay is a monadock - see more in Geology. This hut is set under regrowth karri trees facing Mt Lindesay and is one of the best huts for views. It is also a huge hut - there is plenty of space here!  I had a good phone signal here. For more on the hut and campsite, see here .

For a walk through tour Jinung Beigabup hut see below. This hut is especially nice as it is under the karri trees. And listen to the birds in the back ground - imagine what it would be like at dawn!

Once on Scotsdale Road, we pass Ducketts Mill. Open Thursday to Mondays, 10am to 4 pm, they sell wine, cheese, ice cream, drinks and fudge as well as platters of cheese, meats and preserves. It is an ideal place to stop, or to stock up on some food and drinks for your overnight at the hut if you are heading that way.

Scotsdale Road follows the route of early timber cutting days. Harewood Forest is a 1.5k walk through the beautiful forests of Denmark. There is a bridge crossing the stream from the carpark leading to the trail. There are also a few picnic benches. The stream at the end is the turn-around point - take the same trail back to the carpark. At the corner of Scotsdale Rd and Harewood Rd was a junction for a bush timber railway servicing Millar's timber concessions North of this point. If you turn right along Scotsdale Rd just before Silver Rd on the left is track to horse yards. In 1899, there were 160 horses and 100 bullocks used by Millars timber operations - these yards kept convalescing horses. Keep going to Silver Rd, where the old Scotsdale no 3 mill is opposite the intersection. It is now private property - do not enter.
We ride passed the corner of Fred's Rd and Scotsdale Rd, which was a junction for Millar's tramways, that ran along the ridges of the Bennett Ranges.

Osborne Rd/Roberts Rd/View Rd diversion on to Limbourne Rd has been in place since at least June 2013. As of 2015, it is a permeant realignment. If you are heading North, that means riding up Point Hillier Vista. It is a sealed road heading up hill for about 2km. I have ridden up it towing a BoB trailer and it was rideable in my lowest gear, but it was very tough. Last time I came down it I hit over 61km/hr before I chickened out and applied the brakes. It is steep and long.

Mt Shadforth, which we ride near, offers changing scenes of cattle grazing on pastured farmland to forest and ocean vistas. There are also distant views to the Porongurup Range and Stirling Range, as well as Mount Lindesay.

After sharing a section with the Denmark Nornalup Heritage Trail, the Trail then follows the William Bay Road to Greens Pool. This road is sealed, and is windy and slow, and in the Summer holidays it can be very busy with cars going to the beach.

Greens Pool in William Bay National Park is almost completely sheltered from the waves of the Great Southern Ocean by the rounded rock boulders typical to this area. The long gradual slope of the sea bed allows swimmers to swim in a safe and comfortable environment. Because Denmark does not have a public swimming pool, this is where their swimming lessons are held. The expansively white beach stretches west, past the rock pool across William Bay and Mazzoletti Beach. Greens Pool is one of the most popular destinations in Denmark, and is known internationally.

The next section is a rough dusty gravel road, corrugated by cars, and it can be busy in the Summer months. But it is only 2.3km from Greens Pool to the Trail turn off. The Trail goes to the left, but 100 m straight on is Waterfall Beach, with a small stream that comes out of the scrub and onto the beach. The Trail to Lights Beach is windy, with low hills through the low scrub-covered sand dunes. The Trail often has matting on it to make riding easier and to prevent erosion

We ride passed Lights Beach, which is actually three beaches accessible from one car park. The eastern beach has an ocean-waterfall with waves crashing into Princess Pool, which can be suitable for kids. This beach is designated as a dog beach. The centre beach has large waves and is not really suitable for swimming but gives a fantastic view of William Bay and the Southern Ocean. The western beach has an offshore island and is in William Bay National Park, so no dogs are allowed. The Bibbulmun Track passes directly across the beach. All year round there is a small stream coming from the surrounding countryside and flowing across the beach. Its tea-coloured water is due to the leaves which stain the water with tannin.

As of May 2017, the Trail now follows the Wilderness Ocean Walk (WOW) Trail. This 7 km dual-use trail around Wilson Head has stunning views of the Southern Ocean. The bitumen-sealed trail is 2 m in width and stretches between Lights Beach, passed the wind farm to Ocean Beach. It means the Trail now avoids the Lights Beach Rd  (90km/hr zone with no bike lane) and instead will loop around Wilson Head before rejoining the existing Trail at Lights Beach Rd. Lookouts, seating and interpretive signage feature along the trail's alignment. This section is very windy, with many short, steep hills, blind corners and gravel along the trail, so exercise caution as this section is popular with walkers, runners and riders. This new section definitely enhances the Trail in this area, meaning less time on roads, and more time following the coast.

In case you do not have the new maps, to follow the WOW Trail when riding South to North:
Continue along Ocean beach Rd  instead of turning right for Lights Beach Rd as per MB maps. Cycleway next to road (weaves in and out a bit but is always close to Ocean Beach Rd).
At 2.9 km (just after Ocean Beach car park ) continue straight on into gravel road, following scenic coastal route. 
At 3.2km (300m of dirt) turn right into Wind Farm. Continue on gravel road with gate - bike & walker access only. Follow gravel road to wind turbine No 1 - signposted. Trail is clearly visible next to it.
At approximately 10km, rejoin Munda Biddi at Lights Beach car park.

See the WOW trail below.

The trail passes along the edge of the Ocean Beach car park, and the detour in to see this sheltered beach is worth it. The Trail then continues into Denmark along a cycleway next to the road. At Denmark, it  turns right down the main street (South Coast Highway) next to the Visitors Centre,  located 500 metres west of the Denmark town centre. It is open every day of the year, except Christmas Day, from 9am till 5pm. As usual, they are wealth of information on local knowledge for accommodation, where to eat and places of interest. See:

Denmark is a medium sized country town with a supermarket, many eating out options and all the usual facilities. I am unsure if any shops carry bike spares but Rickett's, on the main street, sell chains, tubes and puncture repair kits. Denmark Cycles is available on 0410 999 506, as I think Gareth operates from home. There is also Monkey Rock Mountain Bike Company, which has a shop near the corner of Hollings Rd and the Highway (next to Ravens Coffee near the road bridge over the Denmark River). Nathan is on 98483316 or 0415 055 069. The local Noongar name for Denmark is Kwoorabup, which means 'place of the black wallaby'. Near the Denmark River mouth on the former railway reserve is some old railway stock and a railway turntable. The old Post Office, used now as a school, was relocated there in 1988. The alcove at the front has a photo display of Denmark's history. For more information on Denmark, see the Denmark Nornalup Heritage trail overview.

Wilson Inlet is the largest inlet on the southern coastline at 20 km wide. It is feed by the Denmark and Hay Rivers, both of which we will cross on the Munda Biddi

Short cut: I have tracked a short cut from the Jinung hut to Denmark via the scenic Scotsdale Rd. The Scotsdale Hills were harvested by the Millars in 1895-1904, and Scotsdale Road mainly follows the old rail line. Instead of a looping 42 km ride via Greens Pool and Lights Beach via the Munda Biddi, this is a 15 km shortcut to get to Denmark quickly if needed.
