Located on the west side of the Cascade Mountains, the park features a 265-foot waterfall, old-growth coniferous forests, and fast- moving rivers and streams.

2011-06-04 Hiked the railroad grade to the lake and upper falls, then the woody trail back. 10+ miles. The trail is very steep ... I think I liked the way we went (down the steep part). Part of the railroad grade trail was essentially a creek, though. Stopped once on the way for lunch, and then later at the lake. Water and restrooms available at the parking lot. At least one restroom available on the trail.
