The Apgar Lookout Trail climbs Apgar Mountain via a series of switchbacks to a fully preserved 1930s Civilian Conservation Corps fire lookout — one of the few still standing in Glacier National Park. The reward at the summit is among the most complete panoramic views in the Lake McDonald corridor: the entire length of the lake laid out below, with the peaks of the Swan Range and Livingston Range framing the horizon.
This is a genuinely strenuous hike. Nearly 1,800 feet of elevation gain packed into 3.7 miles means you're climbing consistently from trailhead to summit with few flat breaks. That said, the switchback pattern is steady rather than brutal — experienced hikers with a reasonable base fitness level will find it very manageable.
The Route
The trail begins at the Apgar Village trailhead and climbs immediately into dense forest. The first mile is shaded and forested — good early momentum. Around mile 1.5, the switchbacks steepen and the tree cover starts to open, revealing the first glimpses of Lake McDonald below.
The upper section (miles 2.5–3.7) is the most rewarding: the trail breaks out of the treeline and runs across an open ridge with expanding views in every direction. The lookout is visible from about a mile out. The final approach is a short, exposed ridgeline walk to the tower itself.
The lookout cab sits on the summit of Apgar Mountain at approximately 5,236 feet. From the catwalk you can see Lake McDonald in its entirety, the Going-to-the-Sun Road corridor, Apgar Village, the Swan Range to the south and the Livingston Range to the north. On clear days the view extends well into Canada.
The Historic Lookout
The Apgar fire lookout was constructed in the 1930s by the Civilian Conservation Corps — part of a network of lookouts built across western national parks during the Depression era. The structure is a standard L-4 cab design, built for long-term occupancy by fire spotters who lived here for weeks at a time during peak fire season.
The lookout is no longer staffed but is maintained by the NPS and volunteers. It's open to the public when rangers are present. The Osborne Firefinder — the circular map-and-sighting instrument used to triangulate fire locations — is still inside. The views from the catwalk are identical to what fire spotters would have seen watching for smoke across the valley for nearly a century.
Lightning risk: The open summit and ridgeline are fully exposed to afternoon thunderstorms, which build quickly in summer. Start early — aim to be below treeline by noon. Check the forecast at the Apgar Visitor Center before departing.
Trailhead & Parking
The trailhead is at Apgar Village, accessible from the main Apgar parking area — the same large lot used for the visitor center and village. Parking is generous here compared to other park trailheads, and the lot is served by the free NPS shuttle, making this one of the easier trails to access without driving. Parking guide →
The trailhead sign is near the Apgar Village camp store. Look for the signed junction for "Apgar Lookout" heading south from the village center.
What to Bring
- 2–3 liters of water minimum — no water sources on the upper trail
- Trekking poles for the descent (steep and rocky in sections)
- Sun protection — the upper ridgeline is fully exposed
- Rain layer and warm layer — summit temperatures can drop suddenly
- Bear spray — always carry in Glacier
- Snacks for a summit break — you've earned it
Best Time to Hike
Mid-July through September is ideal. The trail typically clears of snow by late June, though the summit can hold patches into early July. Fall (late September) is spectacular — larch trees on the lower slopes go golden, crowds are minimal and the air is crisp. Avoid the summit after noon in July and August due to afternoon thunderstorm risk.
This trail does not require a Going-to-the-Sun Road vehicle permit since the trailhead is at Apgar Village, which is in the western park area exempt from permit requirements. No special permits needed beyond park entry.
