Beals Point Campground at Folsom Lake State Recreation Area is a popular choice for travel trailers, offering lakeside settings, boat access, restrooms, and large sites that can accommodate longer rigs. Browns Ravine Campground also provides spacious sites near the water, day-use boat ramps, and shaded loops that work well for unhitching and day trips from Granite Bay. Negro Bar Recreation Area offers a more rustic lakeside experience with several larger campsites and scenic beach access, making it a good option for trailers that need open, flexible parking areas. All of these campgrounds near Granite Bay feature picnic facilities and nearby trail access, but campers should verify site dimensions and amenities when booking.
