Most people speed along the highway between Bakersfield and Barstow without a second glance at the Tehachapi Mountains. Twenty miles from Mojave, hidden in that arid terrain, sits one of California's least-visited state parks — and one of its most intriguing. Tomo-Kahni State Historic Park protects a former winter village of the Kawaiisu people, and you can only see it if you plan well ahead.
The 560-acre preserve, established in 1993, takes its name from the Kawaiisu word for "winter house." For thousands of years it served as a cold-season refuge and gathering place. There are no reconstructed buildings or visitor centres here: instead, the sandstone itself holds the story, with bedrock mortars carved for grinding acorns and buckeyes, petroglyphs of bighorn sheep, and boulders that once anchored shelters of willow and juniper branches.
Access is the catch. Gates stay locked outside guided tours, and the only way in is a docent-led tour booked through Reserve California. Tours cost $20 per person, are capped at 15 people, and run on select weekends in spring and autumn — just 12 dates in 2026, spread across April, May, September and October. Bookings open on 1 January each year, and with fewer than 1,000 visitors annually, spots go quickly. Questions go to Fort Tejon State Historic Park, which administers the site.
Be ready for a proper hike, not a stroll. You meet at the Tehachapi Museum, about 12 miles away, for orientation, then carpool to the park. The 3-mile route starts at 4,000 feet with an 800-foot climb and takes roughly four hours in total. The park is upfront that it isn't for beginners: the terrain is uneven, everyone must stay together, and the trail is largely exposed. Bring sun protection, a hat and layers, since mountain weather can shift fast. A little prep reading helps too — California State Parks publishes a short guide called "Kawaiisu Culture" that's worth skimming before you go.
Why bother with all the logistics? Because this is a genuinely rare kind of visit. With under 20 Google reviews and no developed infrastructure, Tomo-Kahni offers an unfiltered look at Indigenous history in the Mojave-edge highlands, far from any crowd. If you want more of the same after your tour, Red Rock Canyon State Park — the California one, not the Nevada conservation area — has striking desert sandstone cliffs and Kawaiisu connections, and makes an easy add-on to a Tehachapi road trip.
For travellers who prefer their history with some effort attached, this is one of California's most rewarding hidden-in-plain-sight days out.
