This is a really cool and easy walk if you like good views and finding caves, even better on a sunny day! Starting at the Melville Caves picnic area in Kooyoora State Park, you can do the quick 800m circuit up to Melville Cave Lookout finding caves, epic views and boulders along the way! The trail is mostly uphill to the lookout but there's plenty of opportunities to stop along the way and you could easily spend a bit of time wandering through the different crevices, under rocks and admiring the views. You could return the way you came or follow the loop trail back to the picnic area (it's a little less maintained than the way up but still okay to follow).
