Olympic National Park · caps RVs at 35 ft

Olympic's three biomes each enforce different rig caps — Hoh and Kalaloch hold 21-ft loops, Heart O' the Hills tolerates 35 ft, and Hurricane Ridge Road turns back anything over 30 ft well below the summit.

Pick-up

Drop-off

One park, three biomes, and rig-length caps that change by loop.

Kalaloch on the Pacific coast and Hoh Rain Forest on the west side both cap most sites at 21 ft with a handful of pull-throughs reaching 35; Sol Duc and Mora are similar. Heart O' the Hills near Port Angeles is the most generous in the eastern slope at 35 ft across the board. None of the NPS-operated Olympic campgrounds offer hookups — the park's water-table protections rule out plumbing into most sites. Dump stations exist at Sol Duc and Kalaloch. Hurricane Ridge Road's tight switchbacks above 4,000 ft turn back rigs over 30 ft well before the visitor center; plan a tow vehicle if Hurricane Ridge is on the must-see list. Rainforest moisture means the dump-valve gaskets stay damp for weeks.

What the length limit is measuring

Pad length — the rig plus anything it tows
Height — what the branches and the awning need
Turning arc — the swing off the loop road

How the in-park dump station is used

Waste outlet — under the rig, driver side
Ground drain — hose seated, then the valve opens
Rinse standpipe — non-potable, for the hose only

Mount Rainier

Rainier's RV season tracks the snowpack — Cougar Rock and Ohanapecosh open late May but water doesn't go live until June. 35-ft caps, dry-camp only, plow status changes weekly.

North Cascades

Most of North Cascades is roadless wilderness — Highway 20 and Newhalem Creek are the practical RV gateway, 35-ft cap, dry-camp. Colonial Creek opens late June after Skagit snowmelt.
