Lovely but busy spot in North Cascades NP. We were fortunate with really good weather. You can swim in the lake, there is a boat launch and there is a hiking trail across the street. Super convenient. Thunder knob trail.

Bathrooms were clean. Sites a little close. Lots of people come into the park on the weekends from Seattle though it is the least visited of the three Washington Parks. Lovely scenery, turquoise lake.

You need to be prepared when you arrive. Closest camp store is about 25 minutes with limited supplies, but can get you by.. there are restaurants and gas stations in Marblemount, but that is all from what we could tell.
