Within Snoqualmie National Forest, Rimrock Lake Resort operates as a small campground on a rocky peninsula jutting into Rimrock Lake, a reservoir created by dams built roughly a century ago. The US Forest Service facility sits directly alongside Highway 12, with approximately 25 sites offering mixed services from full hookups to basic tent sites with picnic tables and fire pits.
Sites divide between the western shore with lake views and the eastern side that provides shelter from afternoon winds. Most sites require backing in, though a few pull-through options accommodate RVs up to 60 feet. The campground includes a boat launch, bathhouse with shower stalls, and a small office stocking snacks and camping supplies when the owners are available. "Both of our sites had gorgeous views of the lake," notes L & J L..
Cell service remains limited or nonexistent throughout the property, with some reception possible on the lake itself. The reservoir sees light boat traffic, typically just one or two watercraft visible in the distance. Chipmunks frequently visit campsites, and the lake allows swimming during warmer months. Road noise from Highway 12 carries throughout the campground.
Several hiking trails and scenic viewpoints lie within a few miles west on the highway, while campers seeking different settings can explore Peninsula Campground further east along the lake.
