Machins Crater is a 500m, grade 3 Return hike located in Blue Mountains National Park New South Wales. The hike should take approximately 15 mins to complete.


This short walk follows a fairly faint track down into the Machins Crater. The crater was created about 200 million years ago by a volcanic explosion. Today the hole is a very lush environment with a steep sided valley and an old dam wall. An enjoyable short walk.
