Best RV Parks in Washington State: Coast, Rainforest, Volcanoes & Coulee Country (2026)

Washington packs four different RV trips into one state. The Olympic Peninsula is rainforest and a wild Pacific coast with dry national park campgrounds and one hot-springs RV park. The south coast has state parks with full hookups and sixty-foot pads a dune walk from the surf. Mount Rainier is a volcano with a single open RV campground in 2026. And east of the Cascades, Lake Chelan and the Grand Coulee offer sun, warm water and the biggest full-hookup state park campground in the state.

This guide covers the campgrounds we would actually send an RV to, with the 2026 state park fee schedule, site counts from the parks’ own brochures and maps, rig limits, and the reservation windows. It is the pillar for our Washington coverage; the detailed pages are the Olympic National Park RV camping guide, the Mount Rainier RV camping guide and the Sol Duc Hot Springs review. For the drive south, our Oregon coast guide picks up at Astoria.

Quick answer: The best RV parks in Washington by region are Kalaloch and Sol Duc Hot Springs on the Olympic Peninsula, Cape Disappointment and Grayland Beach on the south coast, Deception Pass on Whidbey Island, Cougar Rock at Mount Rainier, and Lake Chelan and Steamboat Rock east of the mountains. State park sites cost $22 to $57 a night depending on season and hookups; national park sites are $20 to $33 with no hookups except Sol Duc’s 17 water-and-electric sites at $58. Full hookups and big-rig pads live at Steamboat Rock, Grayland Beach, Cape Disappointment and Lake Chelan.

Washington state park camping fees (2026)#

Washington State Parks raised campsite rates on May 15, 2025 and has announced no campsite change for 2026; the increases announced for 2026 and 2027 are to reservation fees, senior passes and roofed accommodation.

Site type	Peak (May 15 – Sept 15)	Shoulder (Apr 1 – May 14, Sept 16 – Oct 31)	Winter (Nov – Mar)
Standard	$30–$42	$22–$34	$22
Partial utility (water/electric)	$40–$51	$34–$45	$34
Full utility (water/electric/sewer)	$45–$57	$40–$51	$40
Primitive / water trail	$12	$12	$12

The range within each tier reflects the park’s popularity band. Add a reservation fee, which rose from $5 to $15 for non-residents on April 1, 2026. Trailer dump stations at the parks in this guide charge $5 per use, and overnight moorage, boat launches and extra vehicles carry their own small fees. The Senior Off-Season Pass rises from $75 to $100 on September 1, 2026, with its nightly utility surcharge going from $10 to $12. Cabin and yurt prices increase on January 1, 2027.

Reservations open nine months ahead at washington.goingtocamp.com.

Olympic Peninsula: rainforest and the wild coast#

Olympic National Park’s campgrounds are dry, sized for 21-foot rigs with a handful of 35-foot sites each, and cheap at $24. The peninsula’s one in-park hookup option is the Sol Duc RV Park. Full-hookup private parks sit in Port Angeles, Sequim and Forks. Our Olympic guide compares all eleven RV-usable campgrounds; these are the three to build a trip around.

Kalaloch Campground#

Kalaloch sits on a bluff above a wide sand beach on US 101 in the park’s southern coastal strip, with the lodge store and restaurant a short walk away. The bluff-edge loops are the prize and the shortest; the 35-foot sites are few.

• Sites: 170
• Hookups: None; dump station $10; potable water
• Max rig: 21 ft; a few 35 ft
• Cost: $24 (NPS 2026)
• Reservations: Recreation.gov May 15 – September 20, 2026; first-come the rest of the year
• Season: Year-round; may close in severe weather
• Best for: Surf-sound sleep, Ruby Beach and Beaches 1–4, winter storm-watching in a small rig

Sol Duc Hot Springs RV Park and Campground#

The valley’s hot springs resort runs 17 water-and-electric sites beside 82 dry NPS sites in old growth along the Sol Duc River, 12 miles up a paved road from US 101 near Lake Crescent. Pool sessions are $19 per adult and not included. Full review: Sol Duc Hot Springs RV & Campground.

• Sites: 17 RV (electric + water, no sewer); 82 dry
• Max rig: 36 ft RV park; 21 ft (few 35) campground
• Cost: $58 RV park; $33 campground
• Reservations: Recreation.gov, March 20 – November 1, 2026
• Best for: The only west-side hookups, hot mineral pools and Sol Duc Falls on foot

Hoh Rain Forest Campground#

Seventy-eight sites at the end of the Upper Hoh Road, inside the moss-draped Sitka spruce forest at the Hall of Mosses trailhead. No dump station, so arrive empty.

• Sites: 78
• Hookups: None; no dump
• Max rig: 21 ft; a few up to 35 ft
• Cost: $24
• Reservations: Recreation.gov June 12 – September 8, 2026; first-come otherwise
• Best for: Camping inside the rainforest; Roosevelt elk on the river bar

South coast: full hookups a dune walk from the Pacific#

Washington’s south coast is where the state parks put the utilities. Two parks stand out, one of them mid-renovation.

Cape Disappointment State Park#

At the mouth of the Columbia near Ilwaco, Cape Disappointment has two lighthouses, the Lewis and Clark Interpretive Center on a 200-foot cliff, and a campground laid out by hookup class: the official campsite map lists full hookup sites 1–60, electric-and-water sites 61–91 and standard sites 92–231, plus five hiker/biker sites, yurts and historic vacation houses. The park accommodates RVs and combinations of 45 feet or less; the North Head, interpretive center and Beards Hollow lots do not take RVs.

The important caveat: the campground closed for a major renovation (a new culvert and entrance road, a welcome center and new trails in the Three Waters system) with camping expected to reopen in summer 2026 and some Loop A and B reservations planned from July 1, construction permitting. We could not confirm the reopening at publication; a construction alert still covers October 19–31, 2026 and the boat launch is closed for paving in October. Call (360) 642-3078 before you build a trip around it.

• Sites: 60 full, 31 water/electric, ~140 standard, 5 hiker/biker; yurts and cabins
• Max rig: 45 ft
• Cost: State schedule; trailer dump $5
• Reservations: washington.goingtocamp.com; (360) 642-3078
• Notes: Ocean swimming not advised; Cape D store closed through 2027; North Head Lighthouse open May – September

Grayland Beach State Park#

Grayland is the easiest big-rig beach camping in the Northwest: 60 full-utility sites, 38 partial, four standard and four primitive, sixteen yurts, large paved driveways and a published maximum site length of 60 feet (limited availability). Five trails cross the dunes to the beach, and a county road lets vehicles onto the sand, though camping on the beach is prohibited.

• Sites: 60 full, 38 water/electric, 4 standard, 4 primitive, 16 yurts
• Max rig: 60 ft
• Cost: State schedule; trailer dump $5; unattended vehicle $10/night
• Reservations: washington.goingtocamp.com; (360) 267-4301; yurts 87, 105 and 114–117 by phone
• Notes: About 50 sites are flood-prone and go first-come only from November 1 to April 15; winter beach access can need boots; four restrooms and eight showers

Puget Sound: Deception Pass#

Deception Pass State Park#

The most visited state park in Washington straddles the bridge between Whidbey and Fidalgo islands. The 2024 brochure lists 172 standard and 134 partial-hookup (water and electric) sites across three campgrounds: Cranberry Lake (seasonal; 147 standard, 83 partial mostly in the Forest Loop, five hiker/biker, showers in all restrooms), Quarry Pond (year-round; seven standard, 49 partial, one hiker/biker) and Bowman Bay (seasonal; 18 standard, two partial). There are no sewer hookups; the trailer dump is $5.

Rig length is the thing to check. The park does not publish a campsite maximum, but vehicles over 25 feet are barred from the West Beach and Bowman Bay parking areas, and the forest loops are old. Stays are capped at 10 days in summer and 20 in the off-season, generators run 8 am to 9 pm and quiet hours are 10 pm to 6:30 am. 2026 alerts include a Level 2 burn ban, the Bowman Bay pier closed indefinitely, Pass Lake closed to all use for toxic algae and a washout on the West Beach ADA trail.

• Sites: 172 standard, 134 water/electric
• Hookups: Water and electric only
• Cost: State schedule; trailer dump $5
• Reservations: washington.goingtocamp.com; Quarry Pond open year-round
• Best for: Bridge views, Cranberry Lake swimming, kayaking Bowman Bay, Whidbey Island day trips

Mount Rainier: one campground in 2026#

Mount Rainier has no hookups, no showers and no working dump station in 2026, and only one of its RV campgrounds is open. The Mount Rainier guide covers the gateway parks in Ashford and Packwood that fill the gap.

Cougar Rock Campground#

On the Nisqually-to-Paradise road above Longmire at 3,180 feet, Cougar Rock is the park’s main RV campground: 179 forested sites plus five group sites, flush toilets and water, and Paradise 20 minutes up the hill. The RV limit is 35 feet and the trailer limit 27 feet, measured separately, so a 35-foot fifth wheel does not fit. Loop E is generator-free.

• Sites: 179 + 5 group
• Hookups: None; dump station closed until further notice
• Max rig: 35 ft RV / 27 ft trailer
• Cost: $20 ($60 group)
• Reservations: Recreation.gov
• Generators: 8–10 am, noon–2 pm, 5–7 pm; none in Loop E
• Notes: Ohanapecosh is closed for all of 2026; White River was closed for fire at our last check; arrive with tanks empty

East of the Cascades: sun, lake and coulee#

When the west side is socked in, the dry side is not. These two state parks have the hookups the national parks lack.

Lake Chelan State Park#

On the south shore of the 50-mile glacial lake, with a swimming beach, boat ramp and moorage. The brochure lists 103 standard spaces and 35 utility spaces; the utility sites take RVs to 45 feet, and third-party listings split them as 18 partial and 17 full. A sandwich bar runs daily through Labor Day.

• Sites: 103 standard, 35 utility (full and partial)
• Max rig: 45 ft (utility sites)
• Cost: State schedule; trailer dump $5; boat launch $7/day; overnight moorage $12 (18-ft boats)
• Reservations: washington.goingtocamp.com; (509) 687-3710; reserve early for summer
• Best for: Lake swimming and boating, Chelan’s wineries, a sunny base for the North Cascades

Steamboat Rock State Park#

The biggest full-hookup state park campground in Washington sits on Banks Lake in the Grand Coulee, under an 800-foot basalt butte. The brochure lists 166 full-hookup sites with water, electric and sewer, 26 standard, 18 partial and five equestrian sites, plus primitive camps at Jones Bay and Osborn Bay. Maximum site length is 50 feet (limited), with pull-throughs available. The park is 5,043 acres with 50,000 feet of shoreline, seven boat launches and 320 feet of dock; Grand Coulee Dam and its laser show are a short drive.

• Sites: 166 full, 26 standard, 18 partial, 5 equestrian
• Max rig: 50 ft; pull-throughs
• Cost: State schedule; trailer dump $5; launch $7/day
• Reservations: washington.goingtocamp.com, reservable April 1 – October 31; camping year-round; (509) 633-1304
• Best for: Full hookups in the sun, boating and fishing on Banks Lake, the Steamboat Rock summit hike

Planning a Washington RV trip#

Season#

Mountain and rainforest campgrounds open in late spring and the high passes clear by June or July. July through mid-September is the dry window on the west side. The coast is mild year-round, with winter storm-watching at Kalaloch and Grayland for self-contained rigs. East of the Cascades, June to September is hot and reliable; Steamboat Rock stays open all winter first-come.

Rig size#

Plan the trip around the smallest campsite, not the biggest road. Olympic’s national park sites are 21-foot sites with a few 35s; Cougar Rock is 35 RV / 27 trailer; Deception Pass bars anything over 25 feet from its beach lots. For a 40-footer the state parks on the coast and the dry side (Grayland 60 ft, Steamboat Rock 50 ft, Cape Disappointment and Lake Chelan 45 ft) and the gateway private parks are where you stay.

Reservations#

State parks: nine months ahead at washington.goingtocamp.com, with a $15 non-resident fee since April 2026. National parks: Recreation.gov, with windows that differ by campground (Kalaloch May 15–Sept 20; Hoh June 12–Sept 8; Sol Duc March 20–Nov 1; Cougar Rock all season). Outside those windows most Olympic campgrounds are first-come, which makes May and late September the easy months.

Hookups and dumping#

Assume no hookups in the national parks and a $5 dump at the state parks. With Cougar Rock’s dump closed and Hoh having none, plan dumps in gateway towns. Full hookups: Steamboat Rock, Grayland, Cape Disappointment, Lake Chelan.

Fire, water and wildlife#

Burn bans were in force at most of these parks in September 2026 (wood fires only in designated pits, or none). The coast’s ocean is cold and the park at Cape Disappointment advises against swimming. Bears are active at Sol Duc and across Olympic; store food hard-sided.
