Amenities
The Camp
The sites split between river overlooks and spots tucked back among cedar and ponderosa pine. Paved roads and parking spurs make this accessible for RVs and families, with many sites designed for accessibility. The Middle Fork Tuolumne flows nearby, turning summer afternoons into opportunities for wading and fly fishing for rainbow trout.
Single and double-family sites come with the standard kit: picnic tables, fire rings, flush toilets, and potable water. Firewood is available for a fee. Some sites give you river views; others trade that for more privacy under the canopy.
What to Know
At $46 per night, reservations are required, which makes sense given the proximity to Yosemite's entrances. The Tuolumne River runs 150 miles from the central Sierra Nevada to the San Joaquin River, and you're camping along one of its more accessible stretches.
Nearby
Carlon Falls Trail starts at the nearby Carlon Day Use Area, giving you a quick hike option without breaking camp. For bigger objectives, Hetch Hetchy opens up Yosemite's northern wilderness areas. The Big Oak Flat entrance puts you on the scenic drive through Yosemite Valley, though that's more about the journey than the destination if you're already camping in better country.
The Middle Fork Tuolumne handles swimming and wading when the Sierra summer heat builds up. Rainbow trout fishing works best in the cooler parts of the day.
