Beautiful lake that can be walked around in no time, but offers beautiful views over a short distance. It is very popular here and therefore a bit busier - but still a beautiful destination in Rocky Mountain National Park!

This is a secluded and peaceful lake, achieved after a long hike through a well-marked trail, passing by at least three waterfalls. The first waterfall is Copeland Falls, and later you will pass by Calypso Cascades and Outzel Falls. This is an optional way that will add almost one mile to the one-way trail, but it is surely worth it to enjoy the beautiful falls and their pools. After Outzel Falls the trail goes between a dense forest, passing by some meadows that can be filled with snow during winter. If you intend to hike to the lake during winter and early spring, be sure to wear waterproof hiking shoes or hiking boots. There are some backcountry campsites along the way for those who want to do it as an overnight trip, which requires a campsite reservation: https://www.recreation.gov/search?inventory_type=camping

Black Lake is a pristine lake sitting between Arrowhead and Spearhead peaks, formed by glaciers, with a waterfall coming directly from the top of the mountain. The dark color of the water contrasts with the snow and the rock formation, offering hikers a beautiful place to enjoy some peaceful moments. After Black Lake you can keep going to Frozen Lake, Blue Lake, or Green Lake, each one in a different direction.
