RV route guide
California Highway 1 — San Francisco to Mendocino (the under-driven PCH)
The 175-mile stretch of CA-1 north of San Francisco gets a fraction of Big Sur's traffic and offers the same cinematic coast.
North of the Golden Gate Bridge, California Highway 1 winds through Marin Headlands, hugs the Pacific past Bodega Bay where Hitchcock filmed The Birds, and ends inside redwood country at Leggett where CA-1 joins US-101. The northern PCH carries less than a quarter of Big Sur's traffic, offers similar coastal drama, and has more developed RV-friendly campgrounds. It is the version of PCH most travel writers skip.

Should I drive CA-1 north or south from San Francisco in an RV?
If your rig is over 25 feet, drive CA-1 north — Marin, Bodega Bay, Mendocino. The road is wider, the campgrounds are more numerous, and the traffic is lighter than the Big Sur section south of San Francisco. If you have a small Class B and want the iconic Big Sur photos, drive south. The northern route still gives you redwoods, fog-blasted headlands, and Pacific cliff driving — without the closure history.
- 175 miles from Golden Gate Bridge to Leggett
- Drive time: 5-9 hours with stops
- Class A viable Marin-Bodega Bay; tight Jenner-Westport
- More RV campgrounds than Big Sur
- Best months: late April-October

Cell coverage. Better than Big Sur overall. Marin is fully covered; Sonoma coast has 4G LTE through Bodega Bay and Jenner. The Lost Coast and the Sea Ranch-Gualala-Anchor Bay stretch has spotty service. AT&T is most reliable; T-Mobile thin north of Jenner.
Elevation profile
Sea level at the Golden Gate; climbs to 600 ft over the Marin Headlands; rolls between sea level and 800 ft along the coast; tops out near 1,500 ft inland of Westport.
Lots of short climbs adds up — budget extra fuel
Vehicle restrictions
- No posted statewide restrictions on CA-1 north of San Francisco
- Jenner-to-Westport section narrows and tightens — Class A advisable to detour via US-101 from Bodega Bay
- Mendocino headlands have low overhead branches on some side roads (not on CA-1 itself)
What makes this route different from Big Sur
Northern PCH gets a tenth of Big Sur's RV traffic. The pull-outs are bigger, the campgrounds are easier to reserve, and the road has not had a major closure since the Mendocino fires. You can drive it on a long weekend without competing for every photograph.
The route starts with the Marin Headlands view of San Francisco, runs through Point Reyes National Seashore (an NPS unit, RV camping at Tomales Bay), past Bodega Bay (filming location for The Birds), through the Russian River mouth at Jenner, and along the Sonoma cliffs to Sea Ranch. From Gualala north into Mendocino County, the road climbs and falls through redwood groves and over coastal bluffs until it joins US-101 near Leggett.
RV-friendly stops include Olema Campground near Point Reyes, Bodega Dunes State Park, Russian Gulch State Park outside Mendocino, and Westport-Union Landing State Beach. All take advance reservations via Reserve California.
Pacific Northwest extension planning
Fuel up at Bodega Bay or Gualala
Distances between full-service stations grow north of Jenner. Avoid running below 1/4 tank in remote stretches.
Reserve campgrounds 6+ months ahead in summer
Bodega Dunes, Russian Gulch, and MacKerricher fill May-September.
Plan the Lost Coast as a detour, not a route
Mattole Road is unpaved in places, narrow, and impractical for RVs over 22 ft. Worth a day-trip in a tow vehicle, not the rig.
Check Caltrans QuickMap
Winter rains occasionally close the Sonoma cliffs section.
Save Highway 128 for the return
Inland route via the Anderson Valley wineries — slower but a scenic backhaul to US-101.
Real warnings
Cliff side of the road is the right side northbound
Northbound RV drivers are on the cliff edge. Hug the centre line on tight curves; oncoming traffic gives ground.
cautionWestport to Leggett is the technical section
If your rig is over 25 ft, consider exiting at Leggett-Confusion Hill area to US-101 northbound rather than continuing CA-1 to Eureka.
cautionLogging trucks
Sonoma + Mendocino redwoods see active logging. Loaded logging trucks travel CA-1. Pull over to let them pass.
cautionSea Ranch private community rules
Sea Ranch is a private community with limited public access. Use designated coast trails; do not park on Sea Ranch roads.
info
What Sunset Magazine + Travel + Leisure northern California write-ups doesn't tell you
Most national travel publications cover the northern PCH as a wine-country day trip. That misses the route entirely. CA-1 north is a multi-day RV journey through three distinct landscapes: the urbanised Marin Headlands, the cinematic Sonoma cliffs, and the redwood-edged Mendocino coast.
The other thing magazines miss: the campgrounds are excellent. Reserve California's inventory along this corridor is some of the best-managed in the system. Bodega Dunes has wide pull-throughs. MacKerricher in Mendocino county has direct dune access. None of these get the press of Pfeiffer Big Sur.
Finally, the fuel situation is honest. There is full-service diesel in Marin, Bodega Bay, Gualala, Point Arena, Mendocino, and Westport. You will not run out the way you can on the southern Big Sur cliff section.
Frequently asked questions
- Is Highway 1 the same as PCH?
- California Highway 1 and the Pacific Coast Highway are often used interchangeably, but PCH is a regional name applied to portions of CA-1 in southern California. North of San Francisco, locals say 'Highway 1' or 'the coast highway' rather than PCH.
- Where does CA-1 actually end?
- At Leggett, where it joins US-101. North of Leggett, US-101 continues to Crescent City and Oregon. CA-1's south terminus is at I-5 in Dana Point in Orange County.
- Can I do this route in 3 days?
- Yes if you accept a brisk pace. Day 1: San Francisco-Bodega Bay. Day 2: Bodega Bay-Mendocino. Day 3: Mendocino-Leggett-US-101 north or south. A more relaxed pace is 5 days.
- Is the Lost Coast on this route?
- Not strictly — the Lost Coast is the area where Highway 1 jogs inland because the coast is too rugged for any road. To experience it requires a side-trip via Mattole Road, only suitable for small rigs.
