How deep is the water in the springs? How far is the hike to the water fall?

That's the pool. By the waterfall area, depths vary drastically and suddenly so be careful. And it's not much of a hike.

The springs pool is built like a regular swimming pool with varying depths from kiddie depths of 3ft to 6+ft towards the deep end. The hike from the springs to the falls is under 5 mins.
