Most popular route is ♦Gale River Trail to ♦The Frost Trail to the summit. This is a moderate hike with no steep grades. Galehead Hut is open seasonally and is located at the base of the mountain. Trailhead is located on Gale River Loop Road off RT-3. This road is closed in winter.
Another route would be to take ♦Garfield Trail to ♦Garfield Ridge Trail to the hut and the Frost Trail to the summit. You could bag Garfield in the same day by taking a right onto Garfield Ridge Trail to the summit then backtracking down GRT to Galehead and down Gale River Trail. This would involve a road walk back to your car and is a fairly strenuous day.
