Easy access. Boat accessible. Trails and handicap accessible picnic areas.
Just a few miles north of Foresthill, Sugar Pine is a lesser known reservoir found in Placer County that is surprisingly unpopulated for how much the park provides. A swim suit, some friends, and some good music can be all it takes to have a good time.
There is a boat-launching station that is easy to access right near the parking lot (although the lake did seem almost too small for any larger/faster boats than a fishing boat). Fishing also seems to be pretty popular, with spots such as the dock and fallen trees that provide good casting spots. A good hiking option, alternatively, is the Joshua M. Hardt Memorial Trail (4 miles), an easy hike that loops around the reservoir. Camping spaces are also available with a permit - make your reservation here.
Even though the reservoir is pretty limited in things to do due to it's size, I would highly recommend it to anyone looking for a laid-back day trip or camping trip.
