Stanislaus National Forest · California
Overview Lost Claim attracts families and friends with its convenient location, just 15 miles from the northwest Yosemite National Park boundary in northern California. Deemed as an ideal base camp, visitors can explore not only Yosemite, but also the fantastic wilderness areas of the Stanislaus National Forest. Pets are welcome, but must be compliant with Tuolumne County leash laws.
Sites at Lost Claim are reserved through Recreation.gov. Sites here can be reserved in advance through the official system, and they are claimed fast — cancellations then trickle back all season, unannounced, at any hour of the day or night.

Because sites are booked months ahead, a steady share of reservations get cancelled as trips fall through. Each cancellation instantly returns that site and those nights to the official calendar — first-come, first-served, no waitlist, no announcement. Refreshing the booking page yourself, every few minutes for weeks, works in theory. In practice, the people who get these sites are the ones who hear about the opening first.
ItOpened scans the Recreation.gov calendar for Lost Claim around the clock. When a site matching your dates and your vehicle opens, you get a text with a direct link to it. You book it yourself, in your own account, at the normal price. We never book, hold, or resell — your fee pays for monitoring, and openings are first-come, so speed is the whole game.
