Colonial Creek Campground offers 37 drive-in and walk-in tent sites nestled in old-growth forest on Diablo Lake's north shore, with a public boat launch and fishing pier on the south side accessible via State Route 20.

The campground features clean flush toilets, drinking water, bear boxes, picnic tables, and fire rings at each site, though there are no showers or electrical hookups.

Reservations are required May through early September (with some sites available 7 days in advance), and the nearby Thunder Creek Trail provides excellent hiking access.
