The highest point of the Enchantments Traverse, Aasgard Pass from Colchuck Lake is the most popular route to climb into the Enchantments Core. When it is snow free, the route is pretty straightforward and marked with user cairns. It climbs nearly 2,000 feet in a mile over scree and rock. When covered in snow, it is important to stay to the left to avoid the creeks that may not be visible. Poles and microspikes will be helpful, especially if you are going down this route. I would recommend doing additional research on this route before attempting it so that you have a solid understanding of what the climb entails.

Eagle Peak Saddle is the final part of the trail and the ascent is steep. As you near the saddle and emerge from the forest, you'll be greeted by the striking view of Eagle Peak to the left.

Upon reaching the saddle, it is advised not to proceed further, as the ascent to the peaks is suitable only for experienced hikers.
