This trail is extremely steep, and the weather can be very hot, but it makes the cool cave at the bottom all the more rewarding. The water hole at the bottom will likely have other people present, including kids. The stream pools under the cave and actually continues through a cave, which can be followed through to the other side (but please use caution! This is a stream in a cave--it's dark and could be hazardous). The bottom also features a (very) small waterfall.
The trail itself is less impressive, but it makes the cave at the bottom all the more rewarding. The stream bed is composed of large stones which can be tough on bare feet--bring water shoes or sandals to fully enjoy the space. Bring water toys if you like, but I prefer the natural scene.
