This stunning manmade lake in the North Cascade Mountains was created by the Diablo hydroelectric dam in the Skagit River, but with its remote location and spectacular surroundings, you’d never know it was artificial. The stunning color of the water in shades ranging from pale emerald to brilliant turquoise comes thanks to the minerals in the nearby glaciers, and with the often snow-capped mountains providing the backdrop, it must be one of the world’s most scenic. Many people simply stop at the Diablo Lake Overlook for photos, but there are a number of campgrounds nearby that are accessible by car, plus three small areas for camping on the lake that is boat-in only. A 3.2-mile trail runs along the north shoreline for hiking, and visitors can also enjoy canoeing, kayaking and fishing.
Lake Whatcom is a 10-mile-long lake in Bellingham, providing the perfect place to relax and play. There are a number of accommodation options around the shoreline, from Airbnbs to resorts, that provide the perfect base for fun out on the water, from kayaking and canoeing to boating and fishing. Visitors can also hike or bike along the shore by following the Hertz Trail which brings views of waterfalls and some old-growth forest along the hillsides along with beautiful coves and beaches that are tucked alongside.
