Mary Smith campground is located off of County Road 105, two miles north of the town of Lewiston. This campground offers excellent fishing and tent camping. Mary Smith was picked as one of California's prettiest lake campgrounds. Except for a large cluster of sites at campground entrance (sites 2-9), all campsites are walk-in and clustered in small groups. The campsites are tucked into a lush riparian environment of conifers and deciduous trees, a thick middlestory, and ample wildflowers. Privacy between campsites ranges from fair to outstanding. Each site has a view of the lake and Trinity Alps. There are 17 walk-in camp sites, with a fireplace and picnic table. No trailers allowed. There are both flush and vault restrooms. Glamping Tents are also available.
