Ypsilon Lake Hike

The Ypsilon Lake Hike is a memorable hike in the Rocky Mountain National Park (RMNP). Hike past the Alluvial Fan, along the Roaring River and through lush woodlands to the alpine lake. From Ypsilon Lake, adventurers will be rewarded with amazing views of the encompassing summits that line the horizon. Reserved for intrepid adventurers, this trail is not for the faint of heart. Make sure you are wearing sturdy footwear and pack plenty of water and snacks to keep you fueled along this lengthy excursion. It is also a good idea to check the forecast prior to your adventure to avoid getting caught in inclement weather. Located within the Rocky Mountain National Park (RMNP), visitors are required to purchase a park pass.

From the Lawn Lake Trailhead, the Ypsilon Lake Hike follows the Lawn Lake Trail northwest. Hike up the path, navigating a few switchbacks up to the Alluvial Fan and Horseshoe Falls. After you pass the falls, the crowds will thin. Hike along the Roaring River and at the intersection, veer left. For the remainder of the hike, you will track the Ypsilon Mountain Trail. Ascend the forested route, and you will eventually pass Chipmunk and Upper Chipmunk Lake. Soon after passing these lakes, you will be delivered to Ypsilon Lake.

Enjoy the sight of the shimmering lake that sits in the foreground of the mountainous landscape. Explore the shoreline and rest before beginning your descent. When you are rehydrated and refueled, retrace your steps along the path back to the trailhead.
