Hidden Lake Lookout Hike — North Cascades, WA

The Hidden Lake Lookout Trail in Washington’s North Cascades is an unforgettable 8-mile round trip with roughly 3,300 feet of elevation gain, topping out near 6,900 feet. The route starts in a cool forest, climbs through wildflower meadows, and opens onto rocky alpine slopes where streams and snowfields linger early in the season. Higher up, the trees give way to granite and wide-open views before you reach the historic fire lookout above Hidden Lake. From the summit, you can see jagged peaks like Sahale and Eldorado in every direction. It is a tough climb, but the views make every step worth it.
