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

Avalanche Lake Trailhead offers a moderate day hike through forested terrain to a tranquil alpine lake. Parking is limited; plan ahead and consider the Apgar shuttle during peak season.
Moderate Workout
A day hiker comfortable with a steady ascent and a 4.6β5 mile round trip, 741 ft of gain, typically 3β6 hours. Suited for those who enjoy shaded forest paths, lake scenery, and basic bear safety, hydration, and navigation gear.
Alpine lake framed by cascading waterfalls, with Bearhat Mountain and Little Matterhorn looming over turquoise water.
Moderate difficulty: 4.6 miles round trip with 741 ft of elevation gain. Plan 3β6 hours depending on pace and time spent at the lake; most of the trail is shaded, with a few sunnier stretches near the water.
Parking is limited at the Trail of the Cedars and Avalanche Picnic Area and often fills by midβmorning. To improve odds, arrive before 7:00 AM or in the late afternoon. When spaces are full, consider roadside parking nearby and, during peak season, use the Apgar Visitor Center shuttle as an alternative.
Photo opportunities include Avalanche Lakeβs glassy surface with forested shores and the surrounding peaks, plus the Trail of the Cedars boardwalk. For best lake shots, shoot in early morning light; bring a wide-angle lens for panoramas and a polarizing filter to reduce glare on the water.
β’ Hike around the lake to the far end for cleaner water and better views. β’ Start very early (before 7 AM) or late afternoon to avoid crowds and secure parking. β’ Bear spray is mandatory; stay loud and alert around wildlife.

Rating 4.9 from 795 reviews. The climb is a solid workout with a high-reward alpine lake at the end; the trail is well-maintained but crowded, especially in peak season. The lake and surrounding cliffs deliver a powerful payoff.

This is the trail to visit if you love hiking and live for taking nature pictures! The hike was about 2 miles from parking and when I say this trail is worth the views, please trust me. Would hike it over and over if I lived there. Itβs a magical, beautiful and breathtaking experience. I did feel the burn after hiking this trail and my knees were shot..but so worth it. Heads up: Parts of the hike are uphill and then downhill, flat land, roots and rocks, thereβs also stairs.

Beautiful hike. Trail of cedars is an easy loop and has lots of signage telling you about local wildlife and plant life. If you want to continue to avalanche lake itβs quite steep but worth it. Itβs an extension of trail of cedars and an out and back not a loop!We completed the whole trail and it was about 6 miles. Definitely worth it.

The avalanche lake trail is an about 2.3 miles long one way to the lake. You start on the trail of the cedars first and would recommend taking the boardwalk all of the way to avalanche creek gorge. The gorge is definitely a time for photos from the bridge. The avalanche trail then splits off and has a moderate rise for the next 2 miles to the lake. The view at the lake is great.
