Only one developed campground inside Sequoia National Park can reliably host an RV longer than 22 feet, and even that one comes with a steep access road that makes plenty of drivers sweat. That single fact changes how most RVers should plan this trip. If you’re mapping out RV camping near Sequoia National Park, the giant trees aren’t the hard part. The roads, the rig-length rules, and the shrinking list of open campgrounds are.
This guide breaks down exactly what’s open right now, what’s closed long-term, which roads your rig can actually handle, and how to book a site before it disappears.
Key Takeaways
- Potwisha Campground is the main in-park option built for RVs, but even it has size limits and a winding entrance road.
- Buckeye Flat, South Fork, and parts of Dorst remain closed due to 2026 storm damage, don’t plan around them.
- Generals Highway has real length and width restrictions for big rigs; some sections are not recommended for large motorhomes at all.
- Reservations through Recreation.gov are essential in peak season, and booking windows have shifted for 2026.
- Basing your RV outside the park in nearby gateway towns is often the smarter move for anything over 30 feet.
RV Camping Near Sequoia National Park: Current Campground Access in 2026
As of late 2026, access to sequoia and kings canyon campgrounds is more limited than it’s been in years. Storm damage from earlier in the season has forced extended closures at several sites, and the Park Service has been upfront that some of these won’t reopen on the usual spring timeline [1][2].
Here’s the honest rundown of what’s working and what’s not:
- Open and RV-friendly: Potwisha Campground (year-round), plus select sites at Lodgepole and Dorst when seasonal conditions allow.
- Closed long-term: Buckeye Flat Campground, South Fork Campground, and portions of Dorst Creek Campground remain shut due to flood and erosion damage [1][3].
- Seasonal only: Many high-elevation and Cedar Grove-area sites close completely in winter and reopen in late spring, weather permitting [4][5].
Before locking in any trip, check the park’s current conditions page, closures have been updated multiple times throughout 2026, and what was open in spring may not be open in fall [1][6][7].
If you’re newer to booking park sites in general, it’s worth reading up on national park camping basics before diving into Sequoia’s specific quirks, the rules here are stricter than at many other parks.
Potwisha Campground: The Primary RV Option Inside the Park
Potwisha sits along the Generals Highway at a lower elevation than most of Sequoia’s other campgrounds, which is exactly why it stays open year-round and why it’s the default choice for RVers. It’s also one of the few campgrounds with sites that can physically fit a mid-size rig.
What you need to know about Potwisha:
- Open all year, which makes it valuable during shoulder seasons when higher campgrounds are closed.
- Sites can accommodate RVs and trailers, though exact length limits vary by site and should always be confirmed at booking.
- No hookups, this is a developed-but-rustic campground, not a full-service resort.
- The access road from Highway 198 includes curves that feel tighter than they look on a map, so slow, deliberate driving is non-negotiable.
Potwisha fills fast during summer weekends. If you’re set on this spot, treat the reservation window like a countdown clock, not a “maybe later” task.
Big-Rig Limits: Can Your RV Handle Generals Highway?
This is the section that saves people from a bad day. Generals Highway connects Sequoia and Kings Canyon through dense forest and mountain switchbacks, and it is not built with 40-foot motorhomes in mind.
The National Park Service specifically discourages long vehicles on certain stretches and enforces posted length restrictions in key sections [3][8]. Trailers and motorhomes over the posted limit should not attempt these roads, not because of a technicality, but because the curves genuinely don’t allow safe passage for oversized rigs.
Quick rig-size reality check:
| Rig Type | Generals Highway Suitability |
|---|---|
| Camper van / Class B | Generally fine |
| Travel trailer under 25 ft | Manageable with careful driving |
| Class C motorhome 25-30 ft | Doable, go slow, watch turnouts |
| Fifth wheel or motorhome 35+ ft | Not recommended on restricted segments |
“The road decides your campground, not the other way around.”
Before you commit to driving any RV into the park, review the official oversized vehicle guidance in detail. It’s not optional reading, it’s the difference between a scenic drive and a stressful reverse-out on a one-lane curve [8].
