We ended up doing the Fuller Lakes Trail as a day hike. It is a 5.8 mile (round trip), 1400 foot elevation gain hike up to the upper lake. Once again, it was raining, and we had our rain gear on as we started the hike, and just as we began hiking the rain stopped. What luck!
This trail is one of the nicer ones we've been on. There was relatively little erosion, few plants hanging over the trail, and the grade was comfortable with no very steep parts. The only downfall of this trail was that it was a bit muddy from the recent rains and so was a bit slick in places.
We reached Lower Fuller Lake first and where it crosses the outlet stream there was a beaver dam both just below and another just above the log bridge. We saw a momma duck with 8-10 fuzzy ducklings swimming around the edge of the lake, and another duck out in the middle, but that was the extent of our wildlife viewing for this hike.
