BUG SPRAY -- USE IT! I wish I'd remembered before my last visit. More than once I was attacked by a cloud of aggressive mosquitos.

With some DEET, it's the best hike in the area, mostly thanks to the river: cliffs, crossings, and the waterfall. The gravel holds up well even when it's been raining. I've almost always seen something interesting -- a skunk, or turtles, once I was surprised by a young deer that was invisible in tall grass just feet off the trail, until it bolted.
