This is a nice little pond to refresh in during the summer. The rest of the valley is really nice but a bit low on water in July.

The Lower Falls in Uvas Canyon County Park isn't the biggest or the baddest of all the waterfalls in the area, but it's easy to get to and an easy addition to a longer hike. If waterfalls are your jam, make sure to check out the nearby Black Rock Falls.

Nibbs Knob Trail is a fun trail that leads to an exposed overlook with a picnic table. Most of the trail on the way up is shaded, and there is tons of greenery and a waterfall to keep things interesting.

This is a very small waterfall, which, with its nearby counterparts, makes the Waterfall Loop and Contour Trails special.
