Hungry Valley SVRA

Boggs Mountain Demonstration State Forest is a 3,474-acre CAL FIRE-managed demonstration forest on the flanks of Mount Konocti above Clear Lake in Lake County — Northern California's primary public-land OHV riding destination outside of the Bureau of Land Management areas in the interior, approximately 100 miles north of San Francisco in the North Coast mountains. The demonstration forest designation reflects Boggs Mountain's primary purpose as a managed timber harvesting research and education site; OHV recreation is a compatible secondary use on the forest roads and designated trail corridors within the conifer-dominated forest. The terrain is Lake County's volcanic upland — the Clear Lake Volcanic Field's geology produces the rugged lava-rock soil, the ponderosa pine and Douglas fir forest at 2,500 to 3,849 feet elevation, and the dramatic north-facing escarpments that look out across Clear Lake and the surrounding North Coast mountain ranges. The 50-mile trail network includes fire roads and single-track through the timber management units, giving riders a working forest character that differs from the recreation-only SVRA experience. ATVs, UTVs, and dirt bikes are the primary vehicle classes; full-size trucks and Jeeps can access some fire road sections but the single-track is sized for smaller machines. No day-use fee; California green sticker or street registration required. The CAL FIRE Boggs Mountain office (707-928-4378) manages current trail access and seasonal conditions.

Carnegie State Vehicular Recreation Area is a 1,479-acre California State Parks OHV facility in the Altamont Hills near Livermore in Alameda County — the closest designated OHV riding area to San Francisco and Oakland, approximately 50 miles east of San Francisco and 15 miles east of Livermore at the junction of I-580 and the Tesla Road corridor. The compact size relative to other SVRAs is offset by the terrain density and the sheer number of Bay Area riders it serves: Carnegie draws more riders per acre than virtually any other OHV facility in California given its position at the epicenter of the Bay Area's 7.5-million-person metro. The Altamont Hills terrain is grassland and chaparral on the interior Coast Range: rolling hills with short-grass meadows on the upper exposures, scrub oak and coyote brush in the draws, and the iron-rich clay soil that produces Carnegie's signature mud season in winter and early spring when the trails are at their most dramatic and their most technically demanding. Dirt bikes and ATVs are the primary vehicles — the compact trail network and tight single-track character suit lighter, more maneuverable machines better than full-size UTVs or trucks. A dedicated motocross track and additional skills practice areas supplement the trail network. California green sticker registration is required. The SVRA does not have overnight camping but offers full day-use facilities including restrooms and parking. Thursday-Monday operating schedule applies; contact Carnegie SVRA directly for current conditions (925-447-9027).

Dove Springs Off-Highway Vehicle Open Area is a 3,959-acre BLM-managed OHV open riding area northeast of Mojave in Kern County, California — a free, open-access alternative to the fee-based California State SVRAs, drawing riders from the Antelope Valley, Bakersfield, and the wider southern California inland market who want desert OHV riding without a day-use fee or entrance station. The Mojave Desert terrain at Dove Springs is high desert Mojave at its most classic: Joshua tree woodland across the upper slopes, creosote and black bush scrub in the valley bottoms, and the rocky desert wash system that drains the surrounding hills into the dry lake bed geography of the Mojave basin. The open area designation means riders are not restricted to designated trails — the entire 3,959-acre parcel is open to cross-country travel, giving ATVs, dirt bikes, UTVs, and 4x4 trucks the kind of unrestricted desert riding that marked the pre-NEPA Mojave experience before most BLM land was placed under travel management restrictions. Hills and steep washes provide the technical terrain challenge on what is otherwise flat-to-rolling desert; the rocky volcanic outcroppings in the central area are a focal point for technical riders. A California OHV green sticker or street registration is required; the BLM does not charge a day-use fee at Dove Springs. Primitive camping is available under BLM dispersed rules. The BLM Ridgecrest Field Office (760-384-5400) handles current closure and condition information.

Dumont Dunes OHV Area covers 7,620 acres of BLM public land approximately 31 to 40 miles north of Baker, California, in San Bernardino County — accessible from I-15 via Baker at the Mojave Desert's heart, roughly 60 miles northeast of Barstow and 100 miles northeast of the Inland Empire. The dune system rises from the Mojave Desert floor along the Amargosa River corridor, a mostly dry river valley that drains toward Death Valley National Park's Badwater Basin — the lowest point in North America. Dune heights at Dumont reach 400+ feet at the main dune mass, making the Dumont crest one of the tallest navigable dune faces in the California desert system. ATVs, UTVs, motorcycles, and dune buggies are all permitted throughout the open-vehicle area — the BLM's Dumont designation is an unrestricted open-area format rather than a marked-trail system, meaning navigation is by terrain feature rather than posted markers. The primary season runs November through April when Mojave Desert temperatures are moderate; the site's 1,400-foot elevation provides marginally better conditions than the low-desert valley floors during this period but summer high temperatures still regularly exceed 105°F and make daytime riding impractical in June through September. Primitive camping is available throughout the BLM area on a first-come, first-served basis; Baker provides the nearest fuel and supplies. A BLM permit may be required on peak holiday weekends (contact the Needles Field Office at 760-326-7000).
