Via readers share their favorite swim spots in Oregon, Idaho and Washington.
"Lying on one’s back, floating in beautiful Trillium Lake, and gazing at the eternal majesty of Oregon's Mount Hood makes for a lovely experience." —Joanna Rutter
"Dougan Falls is an amazing spot located in southern Washington along the Washougal River, about an hour from Portland. This swimming hole has crystal clear blue water and is surrounded by trees—in true Pacific Northwest fashion. It's the perfect getaway on a hot summer day." —Elizabeth Donovan
"Mayfield Lake, south of Olympia, Wash., gets my vote. My family has spent every summer there for the past 20 years enjoying swimming, boating, and plain old family fun at nearby Ike Kinswa State Park. There is camping and hiking at the park, plus a beach where families can picnic and swim." —Barbara Stanbro
"Central Oregon's Opal Creek Wilderness, part of the Willamette National Forest, includes Opal Pool, a gorgeous turquoise haven tucked among Douglas fir trees. The hour or two of hiking required to reach this stunning refuge makes it somewhat secluded, and it is well worth the trek." —Jennifer Budke
"I'd like to recommend Redfish Lake, near Stanley, Idaho, as the West's most beautiful swimming spot. It's surrounded by the jagged peaks of the Sawtooth Range, and the water is sparkling clear." —Susie Lambert
"If you want pristine water, a clean mountain setting, and quiet relaxation, Waldo Lake, about 1.5 hours southeast of Eugene, Ore., is the spot. No motorboats are allowed, so bring an inflatable mattress and oat on the clear water or swim out from the sandy beach." —Melanie-Kate Mason
