Situated in the Deschutes National Forest, the warm, clear waters of Suttle Lake make it the perfect spot for summer swimming. After your swim, make sure to visit The Suttle Lodge for well-deserved refreshments.10. Cougar Reservoir
Located in the cascades near Terwilliger Hot Springs, Cougar Reservoir is a serene destination for swimmers and sunbathers. It’s a less-trafficked lake, so it’s a prime spot for those seeking a quiet retreat.When the mercury rises and the Oregon sunshine beckons you outdoors, remember that these stunning mountain lakes are just a short drive away.
