When the late summer arrives and temperatures rise, it helps to have a favorite refuge from the heat. Portland area residents flock to the beaches of Sauvie Island, the Sandy River, the Clackamas River, or perhaps even the Wilson River. For those on the Washington side the Columbia River, the Washougal River is a close resource and one of the best swimming hole rivers in the Pacific Northwest. Often overlooked by Oregonians, the entire length of the Washougal River is sprinkled with deep pools, and sun-kissed rocky outcroppings.
