Northeast summit of Mount Healy

Prepare for a demanding jogging experience on Bison Gulch, a difficult route covering 7.1 miles (11.4 km) with an impressive 3844 feet (1172 metres) of elevation gain. This challenging ascent, estimated to take 4 hours and 4 minutes, plunges you into a rugged, untamed landscape. As you climb, you'll encounter steep river canyons and expansive alpine tundra, leading to sweeping views of the Denali National Park frontcountry. Look for distant glimpses of Denali itself from higher points, such as the Northeast summit of Mount Healy. The trail is known for its relentless steepness, with some sections reaching a 63% grade, often featuring muddy terrain and lingering snowfields.

Access to Bison Gulch quickly takes you away from the main highway, immersing you in a true backcountry setting. If you plan to tackle this route, trekking poles are highly recommended to help navigate the challenging and often muddy terrain. Be prepared for potential snowfields, which can persist into the warmer months. Always carry bear spray and maintain awareness of your surroundings, as you will be in an active wildlife area.

This route is particularly suited for highly experienced trail runners or hikers seeking an extreme workout within Denali National Park and Preserve. As you ascend, you might spot wildlife such as marmots, arctic ground squirrels, and pika. The trail's unique character, with its lack of switchbacks and significant grade, sets it apart as a formidable challenge in the region.
