Pacific Northwest RV Circuit: Waterfalls, Byways, and Waterfront Camps

A Pacific Northwest RV trip is one of the most rewarding summer road journeys in the United States. In one well-shaped loop, you can combine waterfall-lined river gorges, a snow-capped volcano, temperate rainforest, and long stretches of Pacific coastline — all at a pace that suits first-time international RV renters.

This 7-day circuit starts and ends in Portland, Oregon, crosses into Washington for Mount Rainier and Olympic National Park, and returns south along the Oregon Coast. Distances are realistic, major roads are paved and well signed, and campground infrastructure is strong across federal and state park systems.

If you’re planning an RV rental in Portland, this route keeps logistics manageable while delivering classic Pacific Northwest scenery.

7-Day Pacific Northwest RV Itinerary

Day 1 – Portland to the Columbia River Gorge

Drive: About 1 hour

Collect your motorhome and head east on Interstate 84 into the Columbia River Gorge National Scenic Area. This corridor follows the Columbia River between Oregon and Washington and is known for its waterfall concentration and dramatic basalt cliffs.

The Historic Columbia River Highway and viewpoints near waterfall corridors are popular; arrive early and use designated parking suitable for larger vehicles.

Overnight recommendations (federal):

Ainsworth State Park (Oregon State Parks) – forested setting with RV-friendly sites near the Gorge corridor. Official info via Travel Oregon and Oregon State Parks.
Columbia River Gorge National Scenic Area campgrounds (U.S. Forest Service) – book via Recreation.gov.

Practical tip: Use this first night to practice leveling, water connections, and understanding your dump valves.

Day 2 – Columbia River Gorge to Mount Rainier National Park

Drive: About 3–4 hours

Continue north into Washington and travel toward Mount Rainier National Park (nps.gov/mora). Mount Rainier is an active stratovolcano and the highest peak in Washington State.

Roads into the park are paved but winding, with elevation changes. Drive steadily and allow extra time.

Overnight recommendations (inside the park, reservable through Recreation.gov):

Cougar Rock Campground (commonly open in summer; check status and vehicle length limits).
Ohanapecosh Campground (forested setting in a lower-elevation area of the park).

Both are managed by the National Park Service, and regulations, seasonal dates, and length limits are published on the official Mount Rainier pages and Recreation.gov listings.

Fuel before entering the park; services are limited inside.

Day 3 – Mount Rainier to Olympic National Park (Peninsula)

Drive: About 3–4 hours (route dependent)

Travel west toward Olympic National Park (nps.gov/olym), which protects distinct ecosystems: Pacific coastline, temperate rainforest, and alpine high country.

Expect cooler, damper conditions in rainforest areas even during summer.

Overnight recommendations by district (all official NPS campgrounds):

Hoh Campground (rainforest setting; reserve via Recreation.gov when available).
Kalaloch Campground (coastal bluff overlooking the Pacific; check official length limits).

Olympic’s campgrounds vary in road approach and RV length allowances. Always confirm your motorhome size against posted limits.

Day 4 – Exploring Olympic National Park

Drive: Minimal

Dedicate a full day to one district instead of trying to cross the entire park. Olympic is large, and driving times around the peninsula can be longer than they appear on a map.

Options:

Rainforest experience in the Hoh or Quinault valleys.
Pacific coastline at Kalaloch or other designated beach access points.
Mountain scenery near Hurricane Ridge (verify current vehicle guidance and road status on the official park site).

Staying a second night in the same campground reduces setup and breakdown time.

Day 5 – Olympic Peninsula to Washington Coast

Drive: 2–3 hours

Continue south along the outer Washington Coast. Experience Washington (Experience Washington) provides regional overviews of coastal towns and recreation areas.

Overnight recommendations (Washington State Parks; book through official Washington State Parks system):

Cape Disappointment State Park – coastal setting near the mouth of the Columbia River with RV sites.
Grayland Beach State Park – oceanfront access and established RV campground loops.

Check each park’s official page for site sizes, hookup availability, and reservation policies.

Day 6 – Washington Coast to the Oregon Coast (U.S. Highway 101)

Drive: 3–4 hours depending on stops

Cross the Columbia River into Oregon and join portions of U.S. Highway 101. Travel Oregon provides a detailed Oregon Coast overview and highlights state park access along the shoreline.

The route includes sea stacks, cliffside viewpoints, and protected beach access points.

Overnight recommendations (Oregon State Parks; reserve via official state park system):

Fort Stevens State Park – large campground near the Columbia River entrance with established RV infrastructure.
Beverly Beach State Park – forested campground between highway and beach access points.

Highway note: U.S. 101 is fully paved and RV-accessible. Use designated pullouts for photography and allow faster traffic to pass on curves.

Day 7 – Oregon Coast to Portland

Drive: About 2–3 hours inland

Return inland toward Portland. Plan sufficient time for:

Refueling.
Using an approved dump station if required by your rental agreement.
Cleaning and packing.

Portland is a practical gateway with major airport access and easy connections to Interstate highways.

Explore available Oregon RV rentals and consider starting with an RV rental in Portland for maximum route flexibility.
