The Highline Trail is one of the most popular in Glacier NP. It starts on a narrow cliff face and following the contours of the Garden Wall, until Granite Park. The remote Chalet their is booked months to a year in advance. We then head over Swiftcurrent Pass and drop 2300 feet as we join the Bullhead Lake Trail all the way to the Swiftcurrent Motor Inn in Many Glacier. It's a tiring 15.2 miles but amazing!
