Pick-up

Drop-off

Most of the park's land area is wilderness with no road access at all — the road-accessible developed campground footprint is Highway 20 (the North Cascades Highway) and a handful of feeder spurs.

Newhalem Creek Campground sits on Highway 20 at 500 ft, accepts rigs up to 35 ft, runs mid-May through October, dry-camp. Goodell Creek (also Highway 20) is similar with shorter pullouts. Colonial Creek (north and south loops on Diablo Lake) accepts up to 35 ft with a dump station, late June through mid-September only — late season because the Skagit River flooding cycle keeps the loop closed until snowmelt subsides. Highway 20 itself closes November through April between Ross Dam and the Methow side; the western feeder roads stay open year-round to the developed loops.

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.

Olympic

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.
