Isabelle Glacier Hike

The Isabelle Glacier Hike starts out moderately undemanding, but as you venture towards the glacier it escalates quickly. As the trail gains elevation, the terrain becomes exceptionally rocky, and you will have to scramble a talus field before cresting the Isabelle Glacier. Wear sturdy footwear to avoid rolling an ankle! Microspikes and poles might also come in handy. Due to the extreme elevation of the glacier, prepare for inclement weather at the summit. Wear layers and check the forecast prior to setting out to avoid storms. The Isabelle Glacier Hike will stimulate your senses and get your blood pumping!

Add this hike to your adventure bucket-list! The Isabelle Glacier Trail is a one-of-a-kind hike in the Indian Peaks Wilderness. The panoramic view from the glacier of the peaks and landscape below are unlike no other. It is hard to enjoy the journey when you are so focused on the destination, but on this trail, make sure you do. You’ll want to savour every moment of the expedition as you travel through wooded terrain, past a remarkably blue alpine lake, and wildflower meadows all before opening up to stunning vistas of the snow dusted Indian Peaks.

Start this adventure from the Pawnee Pass Trailhead. Heading southeast, the trail will quickly border the shoreline of Long Lake. Continue east on Pawnee Pass trail for a few kilometers before you confront a junction. At this intersection veer left onto Isabelle Glacier Trail. Follow along the path as it hugs the side of the stunning Isabelle Lake which has breathtaking views of the encompassing craggy peaks. Take a break, dip your toes in the water and explore the shoreline!

After revelling in the beauty of Isabelle Lake, continue hiking. As you continue along this route, you will intersect with South St. Vrain Creek several times. There are numerous water sources along this hike, so consider bringing your water filter to lighten your load! Passing along creeks and meadows, the hike will become more exposed as you top the treeline. This is the final and steepest section of the trail.

At this point, the trail begins to rapidly gain elevation and the terrain becomes increasingly rocky. As you begin the ascent towards the glacier there are multiple switchbacks to navigate. Exercise caution and take it slow. After you conquer the tightly wound switchbacks, you will be confronted with a talus field. Scramble through the field before reaching the Isabelle Glacier, nestled in the valley of the Apache and Shoshoni Peaks! From here you will be able to see Apache Peak in the southwest, Shoshoni in the northeast and Navajo Peak and glacier in the south!

Take a breather and explore the glacier before beginning your descent. Be careful as you scramble down the talus and be vigilant of loose rocks. After maneuvering through the switchbacks and the initial decline, maintain along the Isabelle Glacier trail, retracing your steps. Continue along this trail, past Isabelle Lake. Subsequent to passing the lake, you will arrive at a junction, stay right head east on Pawnee Pass Trail. Here you can choose to either continue along Pawnee Pass Trail to the carpark or turn right at the next intersection onto Jean Lunning Trail. This trail diverts you around the eastside of Long Lake before reconnecting you onto Pawnee Pass Trail, guiding you to the parking lot.

In the foreground of the Continental Divide and Indian Peaks, this glacier is anything but uninspiring.
