Plymouth Park Campground operates seasonally from early April through late October with sites ranging from $22-$50 per night and accommodates RVs up to 55 feet. This US Army Corps of Engineers facility provides full hookups including electric, water, and sewer connections alongside standard amenities like restrooms, a dump station, and allows both campfires and pets with reservations available.
The campground features paved sites positioned directly off the main camp road, creating what Nicole L. describes as "pull outs off the camp roadway." Sites offer minimal privacy between neighbors but provide level parking surfaces that work well for any size rig. Green irrigated lawns contrast with the limited shade coverage, and several reviewers note the open layout. Mimi found "large spaces, lots of trees" during her stay, though shade availability appears to vary by site location.
Lake Umatilla provides fishing, kayaking, and swimming opportunities within biking distance or a short drive from camp. The facility includes a playground area where children can play in the open grass spaces. Summer temperatures climb significantly, with one camper noting it "gets really really hot here in the summer." The Columbia River viewpoints require driving approximately 20 minutes from the campground itself, as direct water access from camp involves a longer walk.
Road access proves straightforward for large rigs, and the campground maintains clean restrooms with shower facilities when operational. Some seasonal maintenance issues affect hookups and bathhouse availability, so calling ahead helps avoid disappointment. Staff receives consistent praise for friendliness and responsiveness. Hermiston, Oregon sits six miles away for resupply needs, while campers can explore places to camp around Umatilla for additional regional options.
The campground works best for RV travelers prioritizing easy access and full hookups over privacy or immediate water access.
