Cape Disappointment or Fort Stevens? Pick the Columbia River RV base by which shore gets your days

By Romana

Cape Disappointment State Park and Fort Stevens State Park face the same river mouth from opposite shores. They are close enough to combine in one trip, but not close enough to treat as interchangeable RV bases. An October 28, 2026 route snapshot put the campground-to-campground drive at about 29 miles and 58 minutes. The Astoria-Megler Bridge sits in the middle of that trip.

Choose Cape Disappointment when most of the plan is on the Long Beach Peninsula or inside the Washington park. Choose Fort Stevens when Astoria, the Oregon military site and the Oregon coast will take most of the days. If the itinerary is evenly split, Fort Stevens has the stronger campground-services case, while Cape Disappointment keeps the Washington park's RV-restricted day-use lots from becoming an arrival-day problem.

The bridge is part of the campground choice

For one fixed Oregon-side test point, RVCamping.info routed both campgrounds to the Columbia River Maritime Museum in Astoria. The snapshot returned about 10.6 miles and 23 minutes one way from Fort Stevens, compared with 20.8 miles and 44 minutes from Cape Disappointment. For one Washington-side test point, the Lewis & Clark Interpretive Center, the same routing run returned about 1.9 miles and 10 minutes from Cape Disappointment versus 26.9 miles and 52 minutes from Fort Stevens.^[7]

Those are planning estimates, not traffic promises. Still, they show why counting nights is less useful than counting destination days. A round trip to the Astoria test point from Cape adds roughly 20 miles and 42 minutes over the Fort Stevens base. A round trip to the interpretive-center test point from Fort Stevens adds roughly 50 miles and 84 minutes over the Cape base. Two Washington-focused days from Fort Stevens can therefore mean about 100 extra route miles before beach detours, fuel stops or bridge traffic.

The bridge matters even more for trips in late 2027 and early 2028. ODOT is considering work from September 2027 through May 2028, including as many as 35 weeknight full closures and daytime single-lane operation with flaggers for as many as 90 days. The agency says the schedule is weather dependent and may change.^[5] That is not a reason to avoid either park now. It is a reason to check the project page before booking an opposite-shore itinerary for those dates.

Cape keeps a Washington trip on one side

Cape Disappointment's campground includes standard, partial-hookup and full-hookup choices, and the park publishes a 45-foot maximum for an RV or vehicle combination.^[1] That park-wide figure is only the first gate. The reservation record for the exact site still needs to fit the measured motorhome, or the trailer and tow vehicle as the booking system defines them.

The campground puts North Head, the Lewis & Clark Interpretive Center, Waikiki Beach and the Long Beach Peninsula on the same side of the river. That matters before the sightseeing even begins: Washington State Parks says the parking lots at North Head, the interpretive center and Beards Hollow do not accommodate RVs.^[1] Leave the RV connected at camp and use the tow vehicle or toad for those stops.

Construction has not entirely cleared out. Camping reopened in summer 2026, but the park says campground traffic may still narrow to one lane under flagger control.^[2] The Cape D store is closed through 2026 and into 2027, and the North Jetty is scheduled to close from January 1, 2027, through November 30, 2029.^[1] A lighthouse-and-peninsula trip still works, but a North Jetty-centered trip does not.

Fort has the deeper RV inventory

Fort Stevens makes more sense when the trip is mostly Oregon-side. The official inventory lists 174 full-hookup sites, including 36 pull-throughs, plus 302 sites with electricity and water, including 11 pull-throughs. The campground also has hot showers and an RV dump station.^[3] Those counts do not guarantee the needed dates or driveway, but they amount to a much larger published pool of serviced sites than Cape Disappointment has.

The park can fill a day without crossing the bridge. Its 4,300 acres include the historic military site, Coffenbury Lake, multi-use trails and the Peter Iredale shipwreck area.^[3] Astoria also stays on the same shore. A group that expects museum time, meals in Astoria and an Oregon coast continuation will spend less of the stay repeating U.S. 101 over the river.

Fort Stevens has its own construction caveat. The official park page says the South Loops are currently closed during campground utility work.^[3] Do not use the park's headline site counts as an availability count. Search the live inventory for the travel dates and exact equipment.

Run the hard gates before the itinerary score

A route advantage cannot rescue a campsite that does not fit. Remove a candidate before scoring if any of these checks fails:

1. Measured combination: record the RV's travel length. For a trailer, also record the tow vehicle and the connected or total combination requested by the booking system.
2. Exact driveway: Oregon says every vehicle, including a towed vehicle, must fit inside the paved driveway length shown in its reservation system.^[4] Apply the same conservative test to a Washington site even though Cape also publishes a 45-foot park maximum.
3. Utility need: distinguish full hookups from electricity-and-water service. At Fort Stevens, those are separate inventories.^[3] At Cape, the park likewise separates full, partial and standard sites.^[1]
4. Day-use vehicle: if Cape is the choice, plan a smaller vehicle for the three day-use lots that reject RVs.^[1]
5. Current closure: check the exact loop, the Cape project alert and, for a 2027-28 cross-river plan, the bridge project page.^[2][3][5]

Only then score the trip. In the included worksheet, enter the number of planned days for Astoria/Oregon and for Cape/Long Beach. The sheet multiplies those days by the route snapshot's extra round-trip distance and time. Add a simple preference weight for campground services, exact-site availability and avoiding the bridge. The route result is not a universal winner; it exposes the cost of putting camp on the wrong shore.

Booking windows do not match

The two systems open reservations on different schedules. Washington accepts reservations up to nine months before the first trip date and allows campsite reservations until 2 p.m. on arrival day when inventory remains.^[6] Oregon opens new reservations through six months ahead, releases new sites at 6 a.m. daily and permits same-day online bookings at most parks.^[4]

For a two-park comparison, that mismatch can create a false impression that one campground has more availability. A Cape site may already be bookable while the equivalent Fort Stevens date is still outside Oregon's six-month window. Compare both only after each window has opened, then save the exact-site details with the confirmation.

Which one fits this trip?

Pick Cape Disappointment for a Washington coast stay with lighthouse, interpretive-center and peninsula days, especially when a smaller day-use vehicle will remain at camp with the RV. Pick Fort Stevens for Astoria and Oregon-focused days, or when the larger published inventory of full-hookup and electricity-and-water sites matters.

A split itinerary needs one more decision: either accept repeated bridge time or move once. The worksheet makes that trade visible. Two or three cross-river day trips can cost more driving than a mid-stay campground change, but only if an exact site at both parks survives the rig-fit and utility gates.
