Are there any trails that lead to a waterfall? Or what about a trail with a creek or something?

There are no waterfalls in the park. The wettest area is accessed via Redwood gate. A nice stream that still has some water in it now, runs alongside the Bridal trail and further up alongside the Stream trail.

Agree with Koichiro; when it does rain,the trails will often be too muddy to traverse upon but you may catch something in sight from a lower elevation.

It hasn't rained in a while, so no waterfalls or creeks
