    Two lakes in one trail? You can’t beat it! The Upper Diamond Lake Hike is a great adventure that will take you through the beautiful Colorado terrain before rewarding you with views of crystalline alpine lakes hemmed with snow covered peaks. This is one of our favorite hikes in the Indian Peaks Wilderness, and we think it could be yours too.

    The Upper Diamond Lake Trail is a picturesque hike in the Indian Peaks. This hike will guide you to not one, but two shimmering alpine lakes. The trail itself is fairly moderate with gradual elevation gain and a few undulations before Diamond Lake. Additionally, there are many roots and rocks on the path, so mind your footing.
