How to get there: From Tin Dragon Trail Cottages turn right onto the Tasman Highway. Drive up over the hill out of Branxholm. Continue on the Tasman Highway to Derby, which is about 8 km from Branxholm. Drive through the town and over the bridge you will see the sign and track (RHS) to the tunnel.
Find a car park on the side of the road. Take the lower (right) road for a short walk to the tunnel.
You will see recent earthworks revealing the start of the Cascade MTB track construction. Across the deep ravine small houses appear to cling to the cliff face—part of the charm of Derby. Terrific views for the mountain bikers, if they have time to see it!
This is a short easy walk. You will need to wear gum boots, because as the tunnel slopes downwards it fills with water. The tunnel was opened up in recent years so that it is possible to walk to its end; however the water can get mid-calf deep. You need a reliable torch!
This tunnel was a mighty folly built in the 1880’s by one miner to get his tailings moved from his lease, beneath another miner´s lease.
Apparently his neighbour wouldn’t permit him an easement to remove his tailings! You can certainly see huge piles of tailings rocks near the tunnel.
