There are 19 campsites with picnic tables, fire rings. Other amenities include hand-pumped water, and three vault toilets. There is also one large group site. Tall ponderosa pines and a few aspen trees lord over the high mountain setting of Thompson Reservoir. Recreation opportunities include fishing, hiking, and exploring. The reservoir is stocked once a year with rainbow trout and there is a boat launch. This campground typically opens mid-May and closes mid-October. Heavy snowfall prevents this campground from being used in the winter and early spring. Thompson Reservoir campground is located across the reservoir from the East Bay Campground.
