We drove through here while staying at Anthony Lakes, which is located across the street. Mud Lake Campground is closer to the road than Anthony Lakes, and the lake was more stagnant and less picturesque than the alternative. To be fair, it looked like it was undergoing changes/renovations while we were passing through. Some of the spots are flatter and perhaps more private than at Anthony Lakes. Hiking options nearby are nice. High elevation, so chilly at night for longer than you might expect (~7000 ft elevation).
