Great little quiet spot on Gorge Lake, just on the edge of the Seattle City Light company town, Diablo. It’s one of the only free NPS-run camping area with clean pit toilets, trash/recycling, and a boat launch that I have ever seen. No water spigots, but if you come prepared with a filtration system, you have all the water you need from Gorge Lake. Not much privacy between sites, but tends to attract some cool people. Just seconds off Hwy 20, but you do not hear the road as the small rapids just near the campground naturally drowned out most noise. This the perfect spot for a few days or just an overnight on your way over Washington Pass. Great hiking in the area, including one of the most steep roadside hikes in the park. Sourdough Mountain is no joke, with 3000 feet of elevation gain in the first 3 miles. Cost=free! No permit required, no reservation possible, just good ol’ fashioned first come, first served. Like all car-camping spots within North Cascade NP this place fills up on the weekends during the summer.
