Wollangambe Canyon 1

Be sure to bring your wetsuit for this 2.2 kilometre canyon in the Mount Wilson area of Blue Mountains National Park. Also known as the Wollangambe Canyon Upper Tourist Section, Wollangambe Canyon 1 is a non-technical canyon with scrambles, climbs and many long swims that takes 10 hours to complete.

The long, warm days of summer are the best time to do this canyon to avoid getting too cold in the chilly Wollangambe River waters. A lilo, pack raft or other type of inflatable float is recommended. Only try this canyon if you're moderately fit, and remember to bring your compass because you'll need to navigate the 7 kilometre walk in and out.

To reach Wollangambe Canyon 1, start near Mount Wilson Fire Station and set out along Merewether Lane Fire Trail. After about 800 metres, follow the signposted walking track to Wollangambe River, passing sandstone pagodas along the way. At a steep corner, down-climb 30 metres into a gully using tree roots and follow the gully to the river.

In the canyon you'll need to scramble over massive boulders and make many long swims. Be sure not to miss the exit track, which leads up a gully with a 5 metre exposed climb using rocks and tree roots. Follow the exit track and Northern Fire Trail to make your way back.
