best RV campgrounds in Washington

A cautious Washington RV shortlist focused on length limits, first-come logistics, site counts, and utility details to verify.

This Washington RV guide is a cautious shortlist for length limits, reservation expectations, site counts, and first-come planning. Hookup details are thinner for several DNR-style entries, so confirm utilities directly before building a trip around them.

  2. 02

    Most site inventory

    Mora Campground

    Mora has 94 sites and one accessible site, but RV-specific fit still needs confirmation.

  3. 03

    Small-trailer caution pick

    Rocky Lake Campground

    Rocky Lake is only suitable for very small trailers because of its 20 ft limited-access note.

How These Campgrounds Compare

Moss Creek has the clearest larger-rig fit here at 40 ft. Middle Waddell, Minnie Peterson, Kammenga Canyon, Sheep Creek, and Rocky Lake all require tighter planning, with Rocky Lake limited to very small trailers. Call ahead before arriving with a larger rig at Mora or Porter Creek.

Book-ahead pick

1. Length limits are the first filter

Moss Creek Campground
Moss Creek campground
Moss Creek is the clearest larger-rig fit at 40 ft. Minnie Peterson and Kammenga Canyon are around 30 ft, Middle Waddell needs a direct check because its trailer guidance is mixed, Sheep Creek is tighter at 24 ft, and Rocky Lake is only for very small trailers. Mora and Porter Creek need direct confirmation before you arrive with a larger rig.

2. Do not assume full hookups

Mora Campground image
Mora CampgroundMora has the largest site inventory in this Washington RV shortlist.
Some entries show water, electric, or sewer signals, but the public descriptions are not always detailed enough for RV utility planning. Treat hookups as a question to verify, especially for DNR-style first-come campgrounds. If your setup depends on sewer, 30-amp, 50-amp, or potable water at the pad, confirm before leaving.

3. First-come planning matters here

Capitol State Forest | Department of Natural Resources
Middle Waddell Campground
Moss Creek is the only clear advance-booking option. The other campgrounds need early arrival, alternate dates, and a backup campground, especially the small-site entries: Kammenga Canyon, Rocky Lake, and Sheep Creek. Site-count discrepancies also make Middle Waddell, Rocky Lake, and Sheep Creek worth verifying before you drive out.
Olympia, WABest months: No season dates supplied; check the official forest page before arrival.Booking status unknown

Small Olympic option

4. Season and access vary by region

Olympic Peninsula Forests | Department of Natural Resources
Minnie Peterson Campground
Washington RV conditions shift quickly between the Olympic Peninsula, Capitol State Forest, Little Pend Oreille, and the Columbia Gorge side of the Cascades. Check current road, weather, fire, and water-service notices close to departure, even for entries with year-round or shoulder-season signals.

What to Pack

  • Carry water and a plan for dumping tanks unless the managing agency confirms site-level hookups.
  • Bring leveling blocks and a shorter-rig backup plan for DNR-style forest campgrounds.
  • Screenshot directions and official notices before entering areas with limited cell service.
  • Arrive early for first-come campgrounds with small site counts.
  • Check road, fire, and water-service updates before winter or shoulder-season trips.

Best for: Compact trailers and smaller RVs that fit within a 24 ft limit.

Best for: Very small trailers or compact RVs that can handle limited access near Rocky Lake.

  • 20 ft trailer note

When to go

Mora and Minnie Peterson may work year-round, while Kammenga Canyon is more of a March-November option. For the rest, confirm road access, weather closures, and water availability before shoulder-season or winter trips.

Family fit

Mora offers the largest site inventory and one documented accessible site, which helps when families need more options. Moss Creek is the clearest advance-booking choice. Small first-come campgrounds such as Kammenga Canyon, Rocky Lake, and Sheep Creek need backup plans because site counts and rig fit are limited.

Adult fit

Moss Creek is the cleanest choice for RVers who want a reservation path and a 40 ft length limit. The DNR and forest entries can work for flexible travelers, but they require more verification around hookups, exact site count, and seasonal service. Rocky Lake is a compact-trailer option only because of its 20 ft limited-access note.

Frequently Asked Questions

Which Washington RV campground in this guide can be reserved ahead?â–Ľ

Moss Creek is the clearest advance-booking option here, with a Recreation.gov path and a 40 ft vehicle limit. Treat most other entries as first-come or verify-before-you-go options.

Can I assume these Washington campgrounds have full hookups?â–Ľ

No. Several entries have hookup signals, but agency descriptions are not detailed enough to rely on water, sewer, or electric without confirmation. Call the managing agency or check the official page before planning around full hookups.

Which Washington options work for small trailers?â–Ľ

Rocky Lake is a small-trailer option because of its 20 ft limited-access note. Sheep Creek is tighter at 24 ft, while Middle Waddell, Minnie Peterson, and Kammenga Canyon sit around the high-20s to 30 ft range. Larger rigs should start with Moss Creek or confirm fit directly at Mora and Porter Creek.
