Colonial Creek Campground

Colonial Creek Campground offers two loops (North and South) with 137 total campsites on the shores of Diablo Lake, featuring a boat launch, fishing pier, and direct water access for paddling and fishing with a Washington State license.

The South Loop includes an RV dump station and accommodates trailers up to 36 feet, though most sites are small and not ideal for large RVs; the North Loop is more tent-friendly.

Reservations are required May through September, with limited first-come, first-served availability in winter months (October-May) at the South Loop's walk-in tent sites.
