This is our all time favorite stop in the Olympic national forest. Lake crescent is gorgeous and crystal clear through and through. On a hot day enjoy a day on the lake. Jump in from the boat dock or swim in the swimming area. Rent a canoe or kayak from the general store just up the steps from the lake and have a fun few hours around the lake. The store sells firewood and drinks and some interesting literature about the lake. Drive the road past the campground to a trailhead for the railroad bridge trail. It's a few miles from this side of the lake so make sure you pack a lunch and lots of water. Spend the day jumping in from the bridge at the end of the trail.
