If you’re looking for an amazing autumn getaway near Seattle and you’ve already visited the beautiful crystal clear Blue Lake, head to Colchuck Lake as it is just as gorgeous! Another alpine lake, Colchuck Lake is surrounded by mountains and lined with plenty of boulders to sit on and snack the afternoon away. Take a dip if you dare, but remember your quick-dry towel and warm puffy jacket because Colchuck Lake sits at an elevation of 5,570 feet. We hiked Colchuck during the final weekend of September when the undergrowth was popping with color, the air was crisp, the sun was hiding, and the breeze encouraged a quick pace to the top.
