Overview: The West Glacier Trail is a hidden gem on the west side of Mendenhall Lake in Tongass National Forest, offering an immersive journey through temperate rainforest to a dramatic overlook of Mendenhall Glacier. Hikers traverse lush old-growth forest, cross willow–cottonwood wetlands and alder thickets, then climb a series of stone staircases and rocky switchbacks before arriving at a rocky promontory with sweeping ice-field vistas. Along the way, keep an eye out for bald eagles perched in towering spruce, salmon spawning in side streams, and the occasional black bear foraging near berry patches.

Trail Details:
Trail Length: 6.3 miles round-trip (to glacier overlook)
Duration: 4 to 6 hours
Difficulty Level: Moderate 
Elevation Gain: 1,440 feet
Trail Type: Out-and-back

Key Features:
• Temperate Rainforest: Moss-draped old-growth spruce and hemlock with ferns carpeting the forest floor.
• Wetland Crossings: Boardwalks traverse willow–cottonwood wetlands where you may spot waterfowl or juvenile salmon.
• Stone Staircases: A network of rock steps (some with handrails) negotiates steeper sections and offers brief views across the lake.
• Glacier Overlook: A rocky outcrop about 3.1 miles from the trailhead unveils a panoramic view of Mendenhall Glacier’s terminus, ice caves, and surrounding icefields.

Trailhead Information:
Starting Point: West Glacier Trailhead, reached via Glacier Spur Road off Mendenhall Loop Road (follow signs past the Visitor Center to Montana Creek Road, through Mendenhall Campground, to the dead-end parking area).
Parking: Forest Service lot at trailhead; spaces are limited—arrive by 8 AM in summer. No fee envelope is required for this lot.
Access Fees: No park entrance fee for Tongass National Forest; standard Forest Service parking permit not required, but practice Leave No Trace.

Best Season to Visit:
Late Spring to Early Fall (mid-June to early September): trail is snow-free, with long daylight, wildflowers in bloom, and minimal mosquitoes toward late season.
Edge-of-Summer (July–August): lush understory and highest water flows in side streams—spectacular but expect muddy spots and slick rocks.
Shoulder Season (May or October): possible lingering snow at higher tread; dress in layers and be prepared for early-season chill.

Trail Tips:
• Footwear: Waterproof hiking boots are essential—trail sections can be saturated and slippery.
• Trekking Poles: Helpful on rock staircases and steep climbs.
• Water & Snacks: No potable sources above the wetlands; carry at least 2 L of water and high-energy snacks.
• Bear Safety: Bring bear spray; make noise on blind corners; store food securely if camping nearby.
• Navigation: Trail is well-marked to the overlook, but routes beyond to the glacier edge or Mt. McGinnis spur are unmaintained; proceed only if experienced in cross-country navigation.
• Leave No Trace: Pack out all trash, respect fragile wetland and alpine zone vegetation.

Trail Highlights:
Panoramic Glacier Views: The rock outcrop at mile 3.1 showcases Mendenhall Glacier’s blue-white terminus and the cascading meltwater that feeds Mendenhall Lake—a photographer’s dream, especially in golden morning or late-afternoon light.
Forest-to-Ice Contrast: Experience the shift from dense coastal rainforest to open, rocky glacier forefields—an excellent lesson in glacial ecology and succession, marked by a distinct “trimline” between living forest and barren, scoured terrain.
Wildlife Encounters: Bald eagles hover above the lake; river otters may play in the shallows; keep your lens ready for salmon in spawning season or marmots sunning on exposed boulders.
Seasonal Wildflowers: Late July into August brings beargrass, fireweed, and lupine along the wetter sections near the trailhead—brilliant pops of color against the emerald forest.
Ice Cave Vistas: From a safe distance on stable rock, you can glimpse the glacier’s ice caves and seracs—remember to admire from afar, as icefall is unpredictable.

Additional Information:
Weather: Juneau’s coastal climate means frequent showers and mist; pack waterproof layers and check the Juneau forecast before heading out.
Trail Conditions: After heavy rain or early snowmelt, expect standing water and mud; trail crews maintain wooden boardwalks in wetter stretches, but some rocky sections remain naturally rugged.
Extended Routes: Experienced backcountry travelers sometimes continue beyond the overlook toward Mt. McGinnis or to the glacier edge—obtain proper permits for overnight wilderness travel and always file a trip plan with Forest Service rangers.

Whether you seek a spirited day hike or a deeper exploration of glacier-shaped landscapes, the West Glacier Trail delivers both solitude and spectacle in the heart of Tongass National Forest.
