San Jacinto
Dirt Bike Routes

The San Jacinto Mountains between Palm Springs and Idyllwild are one range with two very different sides. The Garner Valley and Santa Rosa side has designated green-sticker OHV roads; the forested Idyllwild side is plated dual-sport country up to the Black Mountain lookout and the PCT trailheads. The Pacific Crest Trail itself is closed to every motor vehicle — those are places to park, not singletrack to ride. Route geometry and elevation come from the Forest Service MVUM and SRTM.

San Jacinto, California · San Bernardino N.F. · San Jacinto R.D. · 12 routes

Plated street-legal bikes are fine on every route here. The badges below show where green-sticker (non-street-legal) OHVs are allowed — that's the part that varies, sometimes segment by segment.

Green sticker OK

Non-street-legal (green-sticker) OHVs allowed on the route.

Green sticker: partial

Green-sticker allowed on some segments only — read the note.

Street-legal plate only

Street-legal, plated vehicles only — no green-sticker OHVs.

Access unverified

Couldn't verify green-sticker access — confirm on the MVUM.

Sticker rules & the 2026 e-bike law (SB 586)

Electric bikes are OHVs now: under California's SB 586, off-road electric motorcycles count as OHVs. A Sur-Ron or a race-bred Stark Varg (MX) needs a green sticker, a helmet, and visible ID — and like any green-sticker bike, it's restricted to OHV-designated areas. So they follow the same green-sticker access shown on each route, and they can't be plated.

The exception is the road-going Stark Varg EX: it's fully road-homologated in the US (lights, indicators, foot rear brake), so it registers and plates like a street-legal dual-sport — and can ride every route here, including plate-only roads.

Sticker note: since Jan 1 2025, red and green stickers are treated as equally valid year-round in OHV-designated areas; model-year 2022+ non-compliant gas bikes use the new tan sticker. Always carry current registration and a working spark arrestor.
