TrailIceberg Ptarmigan Trailhead
Iceberg Ptarmigan Trail: 9.6 mi RT, 1,210 ft gain to Iceberg Lake. Tough but rewarding.

This short but vicious waterfall hike climbs 651 feet in just 0.8 miles through dense forest and across exposed rocky terrain. You'll earn views of Mount Altyn looming overhead and Lake Sherburne to the south, but the relentless elevation gain is the real test. The payoff—crashing Apikuni Falls and the creek it feeds—justifies the lung-buster, but you'll feel every foot gained on the descent.
Lung buster. Steep elevation gain in a short burst tests your fitness hard.
The crowning view—Apikuni Falls thundering into Apikuni Creek. From the base, Mount Altyn towers overhead to the west and Lake Sherburne spreads below to the south. The waterfall is the objective; don't settle for photos from the approach trail.
• Don't stop at the initial overlook—the best view of the falls is at the very end where the trail reaches the base. • The scramble near the top looks harder than it is; use your hands. • Sunrise hikes catch the falls backlit in mist—dramatic photography angle. • If the trail is muddy, you'll slide on descent; consider skipping after heavy rain.
Late June through September. Road to Many Glacier opens late June; verify Going-to-the-Sun Road status before traveling.
0.8 miles is short, but the elevation gain is punishing. Realistic for fit children 10+, but younger kids will struggle. Supervise closely on the rocky sections—steep dropoffs require constant hand-holding. This is not a family stroll.
Hikers consistently report the elevation gain is relentless but the waterfall payoff justifies the lung-buster. Most praise the short distance and high reward ratio. Some note the crowds in peak season can dampen the experience.
No permits required for day hiking in Glacier National Park.
Not required. Trailhead is accessible by private vehicle. No shuttle service to Apikuni trailhead; park shuttle system serves Logan Pass only (July 1 – September 7).
Steep dropoffs near the falls—the terrain is unstable and unforgiving. Wet rocks turn into ice rinks. Creek crossings can be tricky after snowmelt or rain. Wildlife (bears, mountain lions, bighorn sheep) is present—make noise and keep distance. Afternoon thunderstorms develop fast; lightning is a real threat on exposed ridges.
Rooty and steep. The forest floor is uneven with roots and rocks; the open section features scrambling over loose stone. Not suitable for young children, people with knee problems, or those unaccustomed to steep terrain.

Many Glacier Hotel (1.1 miles west of trailhead) has restaurants, lodging, and ranger services. Apgar Village (larger services, fuel, groceries) is 10+ miles south. Plan water and restroom stops before arriving at the trailhead.

Yes. The dense forest is good bear habitat. Make constant noise, hike in groups if possible, and carry bear spray. Never approach wildlife.
Very. 651 feet in 0.8 miles is about 814 feet per mile—one of the steepest gradients in the park for day hikes. If you struggle on stairs, this will hurt.
Yes, but not recommended. The trail is popular and well-marked, but solo hikers are riskier in bear country and on steep terrain. Hike in pairs or groups.
It's not technical Class 3 scrambling—just steep, loose rock. Use your hands, move deliberately, and test rocks before weight-bearing. Takes 10-15 minutes from the forest line.
Objectively yes. The waterfall and creek views are dramatic. But if you're looking for an easy stroll, this isn't it. The payoff demands the pain.
Good boots are mandatory—the terrain is loose and steep. Trekking poles help on descent. Carry 2L water, sun protection, and a map. No technical climbing gear needed.
