Any waterfalls or nature reserves other than Glenrock and The Watagans?

Hello!

We’re looking for a place to go for a day trip, can be within an hour or so from Newcastle. Mostly looking for somewhere scenic to take a hike and explore, potentially with waterfalls, a swimming hole or some nice views.

Does anyone have any recommendations aside from Glenrock and The Watagans to check out? We do Glenrock, Somersby and The Watagans often so we’re looking for somewhere else for a change.
