Walla Walla Region Swimming Destinations

About Swimming in the Rivers of Southeastern Washington

Southeastern Washington doesn't often make the shortlist for iconic swimming destinations, but those who venture into the Walla Walla region discover something quietly extraordinary: a landscape shaped by ancient catastrophe and carved into a playground of basalt canyons, jade-green rivers, and wide, sun-warmed shores. The Columbia, Snake, and Yakima Rivers wind through this high desert country, offering a variety of informal swimming experiences that range from lazy afternoon floats to more adventurous dips beneath dramatic cliffs.

The Setting: Ice Age Drama Meets High Desert Beauty

You'll know you've arrived somewhere special the moment the terrain opens up around you. These rivers flow through channels sculpted by the Missoula Floods — cataclysmic Ice Age events that stripped the land down to bedrock and left behind the columnar basalt walls that now frame your swim. The cliffs rise in dark, geometric columns above the water, casting cool shadows in the early morning and glowing amber during golden hour. Between the canyon walls, the rivers run clear and cold, flanked by sandy banks, sun-bleached driftwood, and the occasional cottonwood tree offering shade. Herons pick their way along the shallows, ospreys circle overhead, and if you're quiet enough, mule deer may appear at the water's edge. The surrounding shrub-steppe is alive with native grasses, wild sage, and bitterroot — the kind of landscape that smells like the West.

What Swimming Is Like

These are river swims, which means conditions vary with the season and the specific access point you choose. In summer, the water is refreshingly cool rather than cold — a genuine relief when air temperatures in this part of Washington regularly push past 90°F. Clarity tends to be good, especially in calmer eddies and backwaters away from the main current. Depth varies considerably, and some spots offer natural jumping points from low basalt shelves — ideal for the adventurous. Others are shallow and slow-moving, better suited for families with younger swimmers. Because these are informal, unsanctioned swimming spots, there are no lifeguards or safety infrastructure. Wear appropriate footwear for navigating slippery, uneven riverbed rocks, and always scout an area before jumping or diving. Current awareness is essential, particularly at higher water levels in late spring.

Practical Visit Information

The best window to visit runs from late May through September, with July and August offering the warmest water and longest daylight hours. Facilities are sparse to nonexistent at most access points — pack in everything you need, including water, sun protection, and a way to pack out your trash. There is no confirmed fee at these informal river access points. If you want to extend your trip overnight, developed camping is available at Palouse Falls State Park and Hood Park, while BLM lands in the region offer primitive dispersed camping for those comfortable with a more self-sufficient approach.

Plan Your Visit: The Walla Walla region is well-positioned as a base for exploration. The city of Walla Walla itself offers excellent dining, wine tasting, and historic downtown charm. Richland and Kennewick — part of the Tri-Cities area — provide full services, lodging, and easy river access. Yakima anchors the northern end of the region and is surrounded by orchards, farms, and the Yakima River. Whether you're day-tripping from one of these towns or setting up camp for a weekend, the rivers of southeastern Washington reward those willing to seek them out.
