Best Hikes Glacier National Park – Top Trails 2026
Glacier National Park logged 2,893,996 visitors in 2025, and Logan Pass parking plus the Highline Trail fill before 7:00 a.m. on peak days — plan early starts for any trail in this guide.
Glacier National Park offers a wide range of trails from easy lakeside walks to long alpine routes. Per NPS.gov, trail difficulty ranges from easy to strenuous. Bear safety is crucial for hikers; the park service requires safe food storage and recommends carrying bear spray on backcountry trips.
We recommend a short-list approach: pick one classic hike, check shuttle or parking rules, and plan early starts in July and August. Our guide covers Highline, Grinnell Glacier, Iceberg Lake, Avalanche Lake, and Hidden Lake Overlook with trail stats and planning tips, and links to the official trail pages and the interactive park map.
Highline Trail
11.6 miles (one-way to The Loop)
800 ft gain (approx.)
Hard
6–10 hours (one-way to The Loop varies by pace)
July – September
The Highline Trail runs 11.6 miles one-way from Logan Pass to The Loop per park records, with roughly 800 feet of uphill gain on the approach. Per NPS.gov, the route crosses exposed alpine ledges and can be strenuous for unprepared hikers.
Logan Pass is the usual trailhead. Park data shows Logan Pass parking fills early in summer, and a three-hour parking limit applies starting July 1, 2026. Shuttle tickets to Logan Pass operate on a ticketed schedule; Recreation.gov handles the shuttle ticket windows. Based on parking turnover and shuttle service, plan a pre-dawn start or a confirmed shuttle ticket to secure a morning entry slot.
Why it ranks: the Highline offers sustained ridge views of the Garden Wall and glacial valleys. Compared to Avalanche Lake, the Highline trades easier footing for dramatic exposure and higher crowding during peak months.
Grinnell Glacier Trail
11 miles round-trip (common routing)
1,800 ft
Moderate to Hard
6–9 hours
Many Glacier (Ptarmigan/Swiftcurrent area)
Mid-July – September
The Grinnell Glacier Trail covers roughly 11 miles round-trip with about 1,800 feet of elevation gain. Per NPS.gov, Many Glacier trailheads open later in spring when snow melts, and trail conditions vary year to year.
Park alerts note seasonal reroutes and stream crossings can add distance. Glacier status reports show seasonal ice retreat and unstable moraine near the glacier toe, so expect rocky approaches and intermittent snowfields into July some years. Per park alerts, check the Many Glacier access and recent trail notices before you go.
Practical implication: plan sturdy footwear and an early start to avoid afternoon weather. Compared to the Highline, Grinnell offers more lake and glacier viewpoints, but the route requires greater endurance and attention to seasonal hazards.
Which Daypack Should You Choose?
Choose a 20–30L daypack for most Glacier day hikes. For light scrambles and short walks, a 15–20L pack works. For full-day photo missions and extra layers, pick 30–40L. We recommend 20–20L for Highline or Hidden Lake, and 25–30L if you carry a camera and extra layers.
- Recommended volume: 20–30L for typical day hikes
- Hipbelt: small hipbelt for loads over 12 lb
- Hydration: fits 2L bladder
- Keeps load compact on ridge trails
- Fits bear spray and extra layers
- Hydration-compatible
- Smaller packs limit camera gear
- Larger packs add weight on tough climbs
Do You Need Bear Spray?
Bear spray is a required decision item for Glacier backcountry travel. Per NPS.gov, carry bear spray where bears frequent trails. Choose a canister with proven 25–30-foot range and a 7.9-ounce (approx.) canister size common in retail models. Rental options exist near West Glacier and St. Mary; check park concessioners for availability and pricing.
- Typical range: 25–25+ feet (manufacturer specs vary)
- Canister size: commonly 7.9 oz / 225 g (check label)
- Effective at recommended wildlife distances
- Compact and required for many backcountry routes
- Must be readily accessible while hiking
- Rented canisters may have limited shelf life
Which Binoculars Work Best?
For Glacier wildlife viewing, pick 8–42 or 10–42 binoculars. An 8–42 balances weight and field of view. A 10–42 boosts reach in open valleys and for cliff-nesting birds. For scope work, a 20–60 spotting scope pairs well with a light tripod for distant mountain goats and bighorn sheep.
- 8–42: lighter, wider field
- 10–42: higher magnification, more reach
- Spotting scope example: 20–60 for photography-compatible use
- 8–42 is versatile for moving wildlife
- 10–42 helps ID distant subjects
- 10–42 is heavier
- Spotting scopes need a tripod for stable views
Avalanche Lake Trail
4.4 miles round-trip
about 500 ft
Easy to Moderate
2–3.5 hours
Avalanche Creek / Trail of the Cedars
May – October
Avalanche Lake Trail is roughly 4.4 miles round-trip and is often cited as one of Glacier’s most family-friendly hikes. Per NPS.gov, the route follows Avalanche Creek through an old-growth cedar and hemlock forest and ends at a lake ringed by steep cliffs.
Trailhead parking at Avalanche Creek fills early in summer. Park data indicates this area sees high morning demand in May and June during waterfall peak flows. Hikers can combine the Trail of the Cedars boardwalk for an accessible loop, or continue past the lake toward more rugged terrain for a longer day.–Good turnaround points are the lake outlet and the logjam overlook. Compared to the Highline, Avalanche trades expansive alpine views for dense forest and waterfall scenery, with lower average elevation and easier footing.
Iceberg Lake Trail
9.7 miles round-trip (typical routing)
1,275 ft (reported by multiple sources)
Moderate
4–6 hours
Many Glacier / Ptarmigan or Swiftcurrent area
Mid-June – September
Iceberg Lake Trail is commonly listed between 9.3 and 10 miles round-trip with an elevation gain near 1,275 feet. Park pages list the Many Glacier trailhead as the primary access point. Per NPS.gov, this trail crosses varied terrain and remains snow-affected in some years into July.
Seasonal ice hazards can persist on the lake surface and along high approaches. Park alerts and reports call out fixed snowfields and occasional use of route-finding in early summer. Photography turnouts cluster around the final basin where icebergs float in late spring and early summer; aim for morning light on east-facing cliffs for the best color. Wildlife encounters with mountain goats and bighorn sheep are possible; follow park guidance on viewing distances.
Hidden Lake Overlook
2.6 miles round-trip to the overlook
about 529–551 ft
Easy to Moderate
1.5 hours
Logan Pass Visitor Center
July – September
The Hidden Lake Overlook is 2.6 miles round-trip with roughly 529–551 feet of elevation gain per park statistics. The primary trailhead is at Logan Pass. Per NPS.gov, a short boardwalk section leads across alpine meadow to dramatic lake views.
Wildlife sightings here include mountain goats and the occasional grizzly bear (Ursus arctos horribilis), so carry bear spray and give animals space. Logan Pass parking fills before 7:00 a.m. on summer days, and the park’s three-hour parking limit and ticketed shuttle affect timing for this short hike. Based on parking turnover data, plan to arrive at dawn or reserve a shuttle ticket.
Which Hike Should You Choose?
| Trail | Distance | Gain | Time | Difficulty | Best For | Parking Notes |
|---|---|---|---|---|---|---|
| Highline Trail | 11.6 mi (one-way) | 800 ft gain (approx.) | 6–10 hrs (one-way) | Hard | Ridge views, experienced hikers | Logan Pass; shuttle recommended, 3-hour parking limit |
| Grinnell Glacier Trail | 11 mi round-trip | 1,800 ft | 6–9 hrs | Moderate–Hard | Lakes and glaciers, photographers | Many Glacier; parking limited early season |
| Iceberg Lake Trail | 9.7 mi round-trip | 1,275 ft | 4–6 hrs | Moderate | Wildflowers, lake photography | Many Glacier; expect delays due to construction detours some seasons |
| Avalanche Lake Trail | 4.4 mi round-trip | about 500 ft | 2–3.5 hrs | Easy–Moderate | Families, waterfalls | Avalanche Creek; fills early in summer |
| Hidden Lake Overlook | 2.6 mi round-trip | 529–551 ft | 1.5 hrs | Easy–Moderate | Short hikes, wildlife viewing | Logan Pass; shuttle helps avoid parking issues |
