Northern Highline Professional Guide
Detailed Trail Description from our Guidebook
"This is an extended backpack from Granite Park to Fifty Mountain Campground, 11.9 miles (19 km) one way. The northern section of the Highline Trail is accessible only to hikers on extended trips of more than one night. It runs from Granite Park Chalet to Fifty Mountain Campground, connecting the Garden Wall Trail and the Many Glacier complex with trails out of Goat Haunt on Waterton Lake.
The trail stays high in the subalpine country throughout its entire length, and sublime views can be had at any point along the trail. The trail begins by passing around the east side of the chalet and quickly winds around a meadowy spur ridge and out of sight. Meadows along the trail contain glacier lilies, mountain asters, shooting stars, and Indian paintbrushes at different times of the summer."
