Campsites are carved from rich forest along the shores of Diablo Lake. There are 3 accessible campsites
available, 1 site in the north unit and 2 sites in the south unit. Check the main board for current site numbers. Several other campsites contain minimal obstacles, including branches, roots and rocks. Water spigots are located throughout the campground and most restrooms are accessible. The steep boat ramp and campsite fishing docks may be difficult to navigate for people in wheelchairs. An information kiosk is staffed during summer months. Colonial Creek Campground is open year-round. However in winter the water is turned off, there is no garbage service, and the area is not plowed.
