Government Canyon State Natural Area campsites book through ReserveAmerica on a five-month window that opens at 8 a.m. Central. The park publishes 25 total sites in San Antonio, about 1 hour 30 minutes from Austin, and a $6 entrance fee. Camp.land does not run alerts for Texas parks. This guide covers the window, the site types, and what to do when your date is already sold out.
Government Canyon is San Antonio's backyard wilderness: over 12,000 acres of limestone canyons, ancient fossils, and 40 miles of trails about 25 minutes from downtown. Camping is walk-in tent only. No RVs, no generators. Daily visitor permit limits are strict, and you must have a reservation to camp. The park sits atop the Edwards Aquifer recharge zone and can close during heavy rain.
Every site type at Government Canyon State Natural Area releases on the same schedule: five months out at 8 a.m. Central on ReserveAmerica. Permits are limited year-round. Weekends book up immediately when the reservation window opens. March through May is peak for wildflowers and hiking temps. Fall weekends also fill fast. Summer is hot but uncrowded.
What you are choosing between:
Those counts are the published site types on the Government Canyon park page. The 25 total is the park's own standalone figure. Loop names and site numbers are not published in the park file, so this guide does not invent them. There are no RV sites.
Families at Government Canyon should book a walk-in tent site early. The pack-in is short and manageable with kids. Sites farther from the parking area give the most solitude. Weekday nights are quietest. Couples can take any of the standard walk-in tent sites, pack in light, and get a quiet canyon evening.
Government Canyon State Natural Area does not list park-owned cabins and does not list RV sites. Bring a headlamp for the short walk back. Water is available near the campsites, but bring at least 2 liters per person per day for the trails. Mountain biking is allowed on most trails.
Missed the five-month release at Government Canyon State Natural Area? Cancellations still happen. Cancelled sites go straight back into ReserveAmerica, where anyone can book them. The realistic window to check is two to four weeks before your date, when early cancellation penalties are still low enough that fence-sitters bail.
Because Government Canyon is a Texas state natural area, there is no Camp.land alert for it. Check ReserveAmerica directly in that two-to-four-week window, and treat Sunday-through-Tuesday nights as easier targets than Fridays. Summer heat is the easier booking season.

If Government Canyon itself is full, San Antonio has privately owned cabins and vacation rentals on Vrbo. We link the search rather than quote numbers, since inventory changes constantly.
