RV Dump Stations In Three Rivers, California
36.4388° N, 118.9045° W
Quick Overview
Three Rivers is the western gateway to Sequoia and Kings Canyon National Parks, a small Sierra foothills town where the three forks of the Kaweah River meet at about 900 feet. For RVers it is a convenient and scenic base for visiting the largest trees on Earth, with good services, riverfront camping, and, unusually, free dump stations close at hand. The one thing to understand before you arrive is the strict RV size limit on the road up into Sequoia. Across the Three Rivers area we track several dump locations.
Dumping here is easier than at many park gateways. Potwisha Campground, about 4 miles inside the Sequoia entrance, has a free year-round dump station across the highway, and Sequoia RV Ranch also offers a free dump, while Lake Kaweah's Horse Creek campground and Lemon Cove Village have dump facilities and the private parks include sewer at the site. Fuel, groceries, and propane are available in town, which matters because there is no fuel inside the national park.
The critical planning point is rig size. CA-198 becomes the Generals Highway at the entrance, and the steep, hairpinned 16-mile climb to Giant Forest is not advised for vehicles over 22 feet and prohibits single vehicles over 40 feet. Big rigs should enter Sequoia and Kings Canyon via the Big Stump entrance on CA-180 from the Fresno side, or base in Three Rivers and drive up in a tow vehicle. Spring and fall are the prime seasons, avoiding the foothill summer heat. Staying to see the giant trees? See our guide to RV parks and campgrounds in Three Rivers, California.

Three Rivers sits along CA-198 in the Sierra foothills, about 23 to 35 miles east of Visalia and roughly an hour from Fresno via CA-99, with no interstate nearby. CA-198 becomes the Generals Highway at the Sequoia National Park entrance just past town, climbing steeply into the high country. The town is the last stop for fuel, groceries, and propane before the park, since there is no fuel available inside Sequoia.
The route demands care with a big rig. The 16-mile Generals Highway climb to Giant Forest has tight hairpins and gains about 5,000 feet, so vehicles over 22 feet are not advised past Potwisha and single vehicles over 40 feet are prohibited. Big rigs should enter the parks via the Big Stump entrance on CA-180 from Fresno instead, or leave the rig at a Three Rivers campground and drive up in the tow vehicle. Oversized-vehicle parking is provided at General Sherman, the Giant Forest Museum, Lodgepole, and Wolverton for those who do drive up.

Before You Go: RV Trip Essentials
Dump stations are only one piece of the trip puzzle. Before you set out for your trip to Three Rivers, California, it's worth taking thirty minutes to check that the basics are in place — the four areas below are where unprepared RVers most often get stung.
Check your RV insurance coverage
A standard auto policy rarely covers a Class A, Class C, or travel trailer the way a dedicated RV insurance policy does. If you're financing a motorhome, lenders typically require comprehensive and collision; full-timers should additionally price in vacation liability and personal belongings coverage. Rates vary widely by state and travel pattern — compare quotes from multiple RV-focused carriers before each season.
Know your roadside assistance options
RV-specific roadside plans tow motorhomes and trailers that regular AAA coverage won't touch — flat beds, mobile mechanics, tire service for duallies, and even emergency lockouts at remote campgrounds. Good plans cover your spouse and trailer even if you're driving a separate vehicle, and some include trip interruption reimbursement if a breakdown costs you a reservation.
Decide about an extended warranty early
Original manufacturer warranties on new RVs typically run 12–24 months — shorter than most buyers realize. An extended service contract (essentially a mechanical breakdown policy) covers the appliances, slides, levelling systems, and drivetrain components that can run $3,000–$10,000 to replace. The time to price one is before the factory coverage expires, not after something breaks.
Set up a travel rewards card for fuel and fees
A no-annual-fee travel or gas rewards card pays for itself on a single month of RV travel. Expect to spend $400–$800 per week combined on fuel, campgrounds, and propane — 3–5% cash back on gas alone covers the next oil change. For bigger trips, a sign-up bonus can offset campground fees for the whole season.

Dump Station Costs in Three Rivers
Three Rivers is friendlier than most park gateways on dump costs, thanks to the free stations at Potwisha and Sequoia RV Ranch, so you can empty tanks without paying if you plan around them. Lake Kaweah and the private parks charge or include dumping with a paid site. For a multi-night stay, a private full-hookup site removes any separate dump trip, though it costs more than the no-hookup public campgrounds.
For camping, the NPS Potwisha and the Army Corps Lake Kaweah sites are the value options, well below the private full-hookup parks, though they lack hookups. Private parks like Three Rivers Hideaway and Sequoia RV Ranch cost more but deliver full hookups, big-rig room, and riverfront settings. Rates and demand peak in summer, while spring and fall are cheaper and more comfortable. Budget a Visalia stop for a big grocery run or RV service, and remember to fuel up in Three Rivers, since there is none inside the park.

Best Time to Visit Three Rivers by RV
Winter
Nov - Feb
38F - 58F
Crowds: Low
Cool and quiet in the foothills, with snow at park elevation and chain controls on the Generals Highway. Potwisha and the private parks stay open year-round, so dumping is available, but pack for cold nights and check road conditions before heading up into Sequoia.
Spring
Mar - May
48F - 75F
Crowds: Medium
Green foothills, wildflowers, and a rushing Kaweah River make spring a prime time. Comfortable days, easy dumping at Potwisha and the private parks, and lighter crowds than summer. A great window before the foothill heat arrives.
Summer
Jun - Aug
65F - 98F
Crowds: High
Hot in the foothills, often near 100F, though the sequoia high country stays cool and busy. Dump stations and campgrounds see heavy use, so reserve ahead. Start park drives early, and remember the Generals Highway RV limits when planning your rig.
Fall
Sep - Oct
50F - 78F
Crowds: Medium
Mild, clear, and comfortable, one of the best times to visit. Crowds thin after Labour Day, dumping is easy, and the foothill heat has broken. A lovely stretch for the rivers, the lake, and the giant trees before winter snow arrives up high.
Explore the Three Rivers Area
Two habits make Three Rivers easy. First, service the rig in town or just inside the park before heading up: fuel and buy groceries in Three Rivers, since there is no fuel in Sequoia, and use the free dump at Potwisha or Sequoia RV Ranch rather than hunting for one deep in the park. Fill fresh water at the same time.
Second, respect the Generals Highway RV limits. If you are running anything over 22 feet, do not attempt the climb from the Three Rivers side; enter via the Big Stump entrance on CA-180 from Fresno, or stage the big rig at a Three Rivers campground and tour Giant Forest in your tow vehicle. Reserve Potwisha and Lake Kaweah through Recreation.gov ahead of summer and holiday weekends, note that Lake Kaweah needs a booking at least a day out, and visit in spring or fall to dodge the foothill heat, which regularly tops 100F in summer.

Frequently Asked Questions About Dump Stations in Three Rivers
Where can I dump my RV tanks in Three Rivers, California?
You have several good options, including free ones. Potwisha Campground, about 4 miles inside the Sequoia entrance, has a free year-round dump station across the highway, and Sequoia RV Ranch also offers a free dump. Lake Kaweah and Lemon Cove Village have dump facilities too, and the private full-hookup parks in Three Rivers include sewer at the site for guests. Across the Three Rivers area we track several dump locations. Because there is no fuel inside Sequoia and services thin out up high, plan to dump, fuel, and refill water in or near Three Rivers before heading into the park.
Can I take a big rig into Sequoia National Park from Three Rivers?
Not up the Generals Highway from the Three Rivers side. CA-198 becomes the Generals Highway at the Ash Mountain entrance, and the 16-mile climb to Giant Forest has tight hairpins and gains about 5,000 feet, so vehicles over 22 feet are not advised past Potwisha, and single vehicles over 40 feet are prohibited. If you are driving a big rig, enter Sequoia and Kings Canyon via the Big Stump entrance on CA-180 from the Fresno side instead, or leave the rig at a Three Rivers campground and drive up in your tow vehicle. Oversized parking is available at major park attractions.
Are there free RV dump stations near Three Rivers?
Yes, which is unusual and welcome. Potwisha Campground inside Sequoia has a free year-round dump station, and Sequoia RV Ranch offers a free dump as well, so you are not forced to pay to empty tanks in this area. Lake Kaweah's Horse Creek campground and Lemon Cove Village also have dump facilities, and private full-hookup parks bundle sewer into a paid site. This gives Three Rivers better free-dump access than many national park gateways. Still, top off water and empty tanks before heading into Sequoia, since there are no services deep in the park interior.
When is the best time to visit Three Rivers and Sequoia?
Spring and fall are ideal. Spring brings green foothills, wildflowers, and a full, rushing Kaweah River, while fall offers mild, clear days and thinning crowds, both comfortable for the foothills and the giant trees. Summer is hot in the foothills, often near 100F, though the high country around Giant Forest stays cool, and it is the busiest season. Winter is quiet, with snow at park elevation and possible chain controls on the Generals Highway, but the parks and the year-round campgrounds stay open. For the best mix of weather and access, aim for spring or autumn.
Do the campgrounds near Three Rivers have full hookups?
The private ones do. Three Rivers Hideaway has 57 riverfront full-hookup sites and takes big rigs up to 60 feet, and Sequoia RV Ranch has creekside full-hookup pull-throughs, both close to the park entrance. Inside the parks, the NPS campgrounds like Potwisha have no hookups, though Potwisha has a free dump station and water, and the Army Corps campground at Lake Kaweah is also no-hookup but has a dump, flush toilets, and showers. So if you want full hookups and big-rig space, choose a private Three Rivers park; for a in-park setting, camp at Potwisha and run self-sufficiently.
Do I need reservations to camp near Three Rivers?
For the national park and busy seasons, yes. NPS campgrounds in Sequoia and Kings Canyon, including Potwisha, book through Recreation.gov and fill for summer and holiday weekends, so reserve early. Lake Kaweah's Horse Creek campground requires a reservation at least a day ahead and does not take same-day or first-come stays. The private full-hookup parks in Three Rivers, like Three Rivers Hideaway and Sequoia RV Ranch, book direct and also fill in peak season. Spring and fall midweek offer the most flexibility, but for any summer or holiday visit to this popular park gateway, book ahead.
Where do I get fuel, water, and groceries in Three Rivers?
Three Rivers has Shell, Chevron, and Sinclair stations for fuel, the Three Rivers Market for groceries, and propane, which is important because there is no fuel available inside Sequoia National Park. Potable water is available at Potwisha Campground and the private parks. For a larger grocery run, RV service, or anything you cannot find in the small town, Visalia is about 23 to 35 miles west with full services. The smart routine is to fuel up, stock groceries, fill water, and empty tanks in or near Three Rivers before you head up the mountain into the park, where services are minimal.
What is there to see around Three Rivers?
Three Rivers is the gateway to some of California's most spectacular parks. Sequoia National Park, just east, protects the General Sherman Tree, the largest tree on Earth by volume, and the giant sequoia groves of Giant Forest. Neighbouring Kings Canyon National Park, via CA-180, holds a deep glacial canyon and more big trees. Right in town, the Kaweah River offers rafting, fishing, and swimming holes, and Lake Kaweah behind Terminus Dam is popular for boating and water sports. Crystal Cave, a marble cavern inside the park, offers guided tours with tickets. It is a compact base for an enormous amount of scenery.
How hot does Three Rivers get in summer?
Hot, since the town sits at only about 900 feet in the Sierra foothills. Summer highs commonly reach the high 90s and can top 100F, so foothill camping in July and August is genuinely warm, and a powered site with air conditioning or a shaded riverfront spot makes a big difference. The saving grace is elevation: drive up into Sequoia's Giant Forest at around 6,000 to 7,000 feet and temperatures drop dramatically, so you can escape the heat on day trips. Start any foothill activities early, carry plenty of water, and consider spring or fall if you want to avoid the peak heat entirely.
Can I find free or dispersed camping near Three Rivers?
Some, in the surrounding Sequoia National Forest, though options are more limited than the developed campgrounds. Dispersed sites exist on forest land with no hookups, water, or dump facilities, suited to self-contained rigs comfortable with no services. There is no dispersed overnight parking in town or in the national park itself. If you use forest sites, arrive with full fresh water and empty tanks, and plan to dump afterward at the free Potwisha station or Sequoia RV Ranch. For most visitors, the mix of in-park Potwisha and the private full-hookup parks in Three Rivers is simpler and more comfortable.
Is Lake Kaweah worth visiting with an RV?
Yes, especially if you enjoy the water. Lake Kaweah, behind Terminus Dam about 11 miles west of Three Rivers, is a US Army Corps reservoir popular for boating, fishing, and water sports, and its Horse Creek campground offers 80 sites with flush toilets, showers, and a dump station, though no hookups. It makes a good base if you want lake recreation combined with day trips up to Sequoia, and it is often less crowded than the in-park campgrounds. Note that Horse Creek requires a reservation at least a day in advance through Recreation.gov, so plan ahead rather than counting on a walk-up site.
What are the RV length limits for Sequoia and Kings Canyon?
They are strict on the Generals Highway from the Three Rivers side. Vehicles over 22 feet are not advised past Potwisha and Hospital Rock toward Giant Forest, and single vehicles over 40 feet are prohibited on that stretch, because of the tight, steep, historic road. Big rigs should instead use the Big Stump entrance on CA-180 from the Fresno side, which is much more RV-friendly. Once in the park, oversized-vehicle parking is provided at General Sherman, the Giant Forest Museum, Lodgepole, and Wolverton. The simplest approach for a large rig is to camp in Three Rivers and tour the Generals Highway in your tow vehicle.
Is Three Rivers a good base for visiting the sequoias?
It is the classic western base, with a caveat about rig size. Three Rivers sits right at the Ash Mountain entrance to Sequoia National Park, with private full-hookup parks, the free Potwisha dump just inside the park, fuel, groceries, and the Kaweah River all at hand. That makes it ideal for smaller rigs and for anyone willing to day-trip up the mountain by tow vehicle. The one limitation is the Generals Highway's RV restrictions, so big-rig owners who want to drive their whole setup to Giant Forest should enter via CA-180 and Big Stump instead. For most visitors, Three Rivers is a convenient and scenic home base.
Where can I dump my RV tanks in Three Rivers, California?
You have several good options, including free ones. Potwisha Campground, about 4 miles inside the Sequoia entrance, has a free year-round dump station across the highway, and Sequoia RV Ranch also offers a free dump.
