About Hat Creek
Overview
Hat Creek is one of six campgrounds available in the Hat Creek Recreation Area, home to some of the area's best trout fishing. Scenic hiking trails and an active volcanic area can easily be accessed from the facility.
Recreation
Hat Creek is popular for its trophy trout fishing. The cold waters of the creek allow for a refreshing play on hot summer days. Other popular activities in the area include wildlife viewing, hunting, backpacking, hiking and caving.
A variety of day hikes are available in the area, including the Spatter Cones Nature Trail, which is located just across the highway from the campground. The 1.5-mile loop trail provides hikers with a unique opportunity to explore craters, cones and crevices, as well as other geologic features left by the Hat Creek Lava Flow.
Nearby, visitors can take a self-guided tour of Subway Cave. The trail is less than a half-mile long and explores the underground world of a lava tube. Visitors are encouraged to bring flashlights for hiking through the cave.
Facilities
Hat Creek offers three group campsites that can accommodate up to 50 people each. Individual sites are also available on a first-come, first-served basis.
Picnic tables and campfire rings with grills are provided, as are accessible flush and vault toilets, utility sinks and drinking water. The RV dump-station is located 1.5 miles north of the campground behind the Old Station Visitors Center.
Natural Features
The campground is situated next to Hat Creek in a mixed conifer forest at an elevation of about 4,390 feet. Pine needles, grasses and volcanic rocks cover the forest floor. Sites are widely spaced for privacy.
Nearby Attractions
The campground is located about a mile west of the town of Old Station, and 12 miles east of the northwest entrance to Lassen Volcanic National Park, where active, hissing fumaroles and boiling mud pots are continually shaping the landscape.
The Pacific Crest National Scenic Trail can be accessed near the Spatter Cones Nature Trailhead.

How do I get a reservation at Hat Creek?
Reservations for Hat Creek are made through Recreation.gov. 76.5% of tracked site-nights are not currently open for online reservation; 31 of 132 remain open. Campsite Sniper has also detected 8 site openings here in the last 90 days, so further dates may appear. Pick a site on the map to see its calendar, or set a free Campsite Sniper alert. You complete the reservation yourself on Recreation.gov.
Does Campsite Sniper book this campground for me?
No. Campsite Sniper sends alerts and direct Recreation.gov links. It never books, pays for, holds, hoards, or resells reservations.
How current is this availability data?
Campsite Sniper re-checks public Recreation.gov availability for this facility every hour and republishes whenever anything changes. This facility's data last changed at Nov 2, 2026 16:20 UTC; an older timestamp means nothing has changed since that time, not that checking stopped. Always confirm final availability on Recreation.gov when you book.
How often do new openings appear at Hat Creek?
Campsite Sniper detected 8 site-date openings here over the last 90 days, none in the last 7. A free alert watches around the clock and pings you the moment one appears.
Can I get a multi-night stay at Hat Creek?
3 three-night openings are showing, counting only runs where the SAME site is free for all three nights. The soonest starts Apr 23, 2027 at site GS1. Confirm and book on Recreation.gov.
Which sites at Hat Creek fit a 35-foot RV?
3 of the 3 sites that support RV analysis have a recorded maximum of 35 ft or more; the longest recorded is 40 ft.
Which month has the most availability at Hat Creek?
April 2027, with 22 open site-nights in the current snapshot of 96.
When is the next open date at Hat Creek?
Campsite Sniper cannot answer that from the current snapshot. The availability data held for Hat Creek begins Apr 23, 2027 — about 172 days after this snapshot was taken, so any earlier dates are outside what Campsite Sniper is tracking here rather than known to be unavailable. Check Recreation.gov for dates before Apr 23, 2027.
