Camping near Cathlamet offers access to the diverse waterways of southwestern Washington where the Columbia River widens to nearly 4 miles across before meeting the Pacific Ocean. Elevation remains low, typically under 100 feet, with riverside campsites experiencing morning fog patterns common to the Lower Columbia region. Winter campers can expect average rainfall of 6-10 inches monthly from November through January, while summer brings warm days and cooler nights with temperatures ranging from 50-80°F.
What to do
Fishing opportunities abound: County Line Park, located eight miles east of Cathlamet, provides direct river access for anglers seeking sturgeon, salmon, and steelhead. According to Alan K., the park offers "great spots right on the Columbia River" with "clean restrooms, and shower" facilities that make it comfortable for multi-day fishing trips.
Kayaking the sloughs: Elochoman Marina provides excellent paddling access with calm water options. Donald H. notes it's "great for kayak and brew pub" with "beautiful sunset and walking distance to a pub and pizza place" making it convenient to combine recreation with dining options.
Wildlife viewing: At Seaquest State Park, campers can observe local fauna in their natural habitat. Though slightly inland, Toni V. reports there are "many trails to walk down with beautiful surroundings" where deer sightings are common among the forested settings.
Mount St. Helens excursions: Using Seaquest State Park as a base camp puts you within driving distance of Mount St. Helens. Carol mentions "it was a 10 hour day to do the loop in order to see the east side, with only one short hike thrown in" but the "signage at the overlooks is very good" for self-guided exploration.
What campers like
Private riverside sites: Skamokawa Vista Park earns praise for its range of sites. According to Jen R., "depending on what you're looking for in a campsite, Vista Park either delights or disappoints" with the highlight being "great views of the Columbia and the Oregon coast" and "awesome beach access."
Maritime traffic watching: The Columbia serves as a major shipping channel, providing unique entertainment. Jim J. commented on Skamokawa Vista Park: "This is a beautiful park. It's not huge and there are not a ton of full hookup sites, but it's a very sweet spot on the Columbia River."
Clean facilities: Northrup Creek Horse Campground receives consistent praise for maintenance. Daniel S. called it "a hidden gem of a campsite" noting "the bathrooms were clean" and "the road in was in great condition." Though primarily designed for equestrian use, it offers tent and small RV sites within Clatsop State Forest.
Waterfall access: For those willing to explore beyond Cathlamet proper, Beaver Falls Trailhead provides free dispersed camping with natural attractions. John P. reports: "Not scenic (though the waterfall that is a short hike away is)" and "my partner and I angled our vehicle to block our tent from the road and slept like rocks."
What you should know
Winter camping reality: Winter visitors should prepare for persistent wet conditions. The campgrounds remain quiet in off-season months with Angela M. noting at Elochoman Marina: "It's not fancy, no water or electricity at the tent sites. However you have a great view of the water and it's fairly quiet."
Highway noise impacts: Some riverside sites experience road noise. Troy P. warns about Elochoman Marina: "Semi's ride their compression brakes down the hill on the highway all night," despite the "really cool location" that makes it otherwise appealing.
Limited tent options: County Line Park has shifted away from tent accommodation according to Mary C., who noted "No more tent camping" among the cons in her review, making it primarily suitable for RV travelers.
Fire restrictions: Check current fire rules as they vary by location and season. Mary C. also mentioned County Line Park has "No fires" as a drawback, while other nearby campgrounds do permit campfires when conditions allow.
Tips for camping with families
Playgrounds and activities: Fort Stevens State Park across the river in Oregon offers extensive recreation options. Jenny M. says "So much for kids to do from exploring, riding bikes, fishing and going to the amphitheater for some stories," making it worth the drive over the Astoria-Megler Bridge.
Beach access considerations: While Columbia River beaches exist near Cathlamet, better sandy beaches can be found at Fort Stevens. Jenny notes, "Campground not right on beach but close enough to ride bike or drive" with convenient signage for returning to your campsite area.
Mosquito preparation: Insect protection is essential, particularly in shaded areas. Gail S. advises Fort Stevens visitors to "Bring mosquito repellent!" despite the appeal of "visiting the forts and cannons" and the "Iredale shipwreck especially at sunset."
Campground playground options: Seaquest State Park includes play equipment within the campground. Mary C. mentioned "My kids loved the addition of a playground. Many parks don't have this and it kept them entertained for hours."
Tips from RVers
Hookup locations: At Skamokawa Vista Park, consider site placement carefully. Jen R. cautions "Many of the sites have really awkward setups—hookups on the wrong side, fire pits far away from pad, etc. The sites are really close together."
Year-round access: Elochoman Marina provides camping throughout all seasons. Jon R. notes this "small RV park is located on the Columbia River in Cathlamet WA" with "sites varying from tent to full hookup" giving options for different rig sizes and needs.
Size restrictions: Not all campgrounds accommodate larger RVs. At Northrup Creek Horse Campground, Daniel S. observed that while it's "primarily a horse-friendly campsite, there are few RV/tent sites, but definitely not friendly for larger RVs."
Internet connectivity: Cell service varies substantially throughout the region. Kim G. reported that Seaquest State Park has "No cell (occasionally 1 bar LTE AT&T)" and is "too heavily forested for Starlink" which required them to "leave early Monday morning since we were working and needed internet."
