Overview

About This Trail

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.

Highlights

Difficulty Level

Moderate Workout

Hike If / Skip If

A day hiker comfortable with a steady ascent and a 4.6–5 mile round trip, 550–757 ft of gain, typically 3–6 hours. Suited for those who enjoy shaded forest paths, lake scenery, and basic bear safety, hydration, and navigation gear.

Trail Highlights

Alpine lake framed by cascading waterfalls, with Bearhat Mountain and Little Matterhorn looming over turquoise water.

The Sweat Reality

Moderate difficulty: 4.6–5 miles round trip with 550–757 ft of elevation gain. Plan 3–6 hours depending on pace and time spent at the lake; most of the trail is shaded, with a few sunnier stretches near the water.

The Arrival Protocol

Parking is limited at the Trail of the Cedars and Avalanche Picnic Area and often fills by mid‑morning. 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.

The Payoff

Photo opportunities include Avalanche Lake’s 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.

Insider Tips

• Hike around the lake to the far end for cleaner water and better views. • Start very early (before 7 AM) or late afternoon to avoid crowds and secure parking. • Bear spray is mandatory; stay loud and alert around wildlife.

Best Season to Hike

Summer (July–August); May–September is the hiking window

Hiking Tips

  • Hydration: carry 2L minimum.
  • Bear spray is mandatory; keep it accessible.
  • Start cold; the climb warms quickly.
  • Bring offline maps; cell service is a dead zone.

Family Info

Generally family-friendly, but steeper sections may require a carrier for very young children
