First set the mood:
The Apgar Lookout Trail is located almost in the southwestern corner of Glacier National Park. To get there drive about a half-mile north from the West Glacier Entrance Station, and then turn left towards the Glacier Institute. Drive a short distance to the next junction and turn right (away from the Glacier Institute), then almost immediately make a turn towards the left - just before reaching the Swan Mountain Outfitters horse corral. From here you'll drive another 1.9 miles on a single lane gravel road to reach the trailhead.
Most campgrounds in Glacier are first-come first-served with the exception of Fish Creek, St. Mary, some of Many Glacier, and half of the group sites in Apgar. These campsites can be reserved in advance: FYI Campgrounds are reservable no more than 12 months in advance.
Roughly three-quarters of a mile from the parking area the trail begins a steady climb up the southwestern slopes of the mountain. Over the next 2.7 miles hikers will climb roughly 1700 feet to reach the ridge just below the lookout.
From Apgar Lookout, and the area surrounding the fire tower, hikers will have grand views of the entire length of Lake McDonald, as well as the high peaks into the heart of Glacier. Unfortunately those views are partially obstructed by trees and a TV transmitter tower, but are nonetheless still spectacular
