About this campground
Discover your own island paradise at Plymouth Campground, where 32 well-appointed campsites with electric hookups await on a scenic island in Lake Umatilla. This Columbia River gem invites families to splash in the designated swim beach, watch children explore the playground, or simply relax in the spacious day-use area while taking in sweeping river views.
Plymouth Park Campground offers a variety of camping options, primarily focused on RV and tent sites. Some sites include full hookups, while others provide just water and electricity.
Historical SignificanceStep back in time at the nearby McNary Dam and Visitor Center, where the story of the Columbia River unfolds through engaging exhibits. Discover how this engineering marvel transformed the region while learning about the delicate balance between human innovation and the river's ancient ecology that continues to shape life along these shores.
Weather and SeasonsExperience the dramatic beauty of high desert summers where the sun reigns supreme and temperatures can soar above 100°F, creating perfect conditions for early morning adventures and refreshing afternoon swims. The intense summer heat gives way to crisp mornings and golden evenings that paint the landscape in ever-changing light.
ElevationPerched at high desert elevation, the campground offers that distinctive dry-air clarity that makes stars seem closer and sunsets more vivid. The elevation creates a unique microclimate where desert meets river, offering cooler breezes off the water even on the warmest days.
Natural Features and SceneryWake to the haunting calls of waterfowl echoing across Lake Umatilla, where graceful mule deer emerge from groves of Russian Olive trees at dawn. Raptors circle overhead against vast blue skies while the aromatic sagebrush releases its signature scent in the evening air, creating an authentic high desert experience enhanced by the constant presence of the mighty Columbia River.
Geological RegionThis remarkable island oasis rises from the Columbia River like a high desert mirage, where towering sagebrush and silvery Russian Olive trees create a striking contrast against the water. The unique geological setting combines the raw beauty of desert landscapes with the life-giving presence of one of North America's great rivers, offering campers a rare opportunity to experience two distinct ecosystems in one extraordinary location.
