Lena Lake campground offers a rewarding view after a steady climb up meandering switchbacks. Started at the trailhead around 6 pm and made it to the campground around dusk. We were pleased to be greeted by a couple of somewhat overly friendly mountain goats on the way, and saw fish surface for bugs on the lake as the sun went down. There are several campgrounds surrounding the lake, complete with locking bathrooms (no flush toilets or water). The only downside is that this lake can attract a lot of campers on weekends, so if you go on a Friday night bring enough trail mix to share!
