Colorado’s high alpine lakes are nothing short of breathtaking. From Silverton to Vail, many of these pristine bodies of water can be found above timberline, harbor healthy populations of trout, and offer dazzling displays of wildflowers and towering rock formations. Lace-up your trail stompers and climb into the clouds with these ethereal high alpine lake hikes.
An alpine lake is really just a high-altitude lake. They can be crystal clear, unlike some of the lakes at lower altitudes, because the cold water decreases the speed at which algae and moss can grow in the water. They are so plentiful in Colorado, virtually any mountain hike you take will find one along the way.
