Hiking in Grizzly Lake: trails, map and practical info

Description

Grizzly Lake is one of those destinations in the Tombstone Mountains that earns its reputation the hard way — through raw, unfiltered Yukon wilderness. Tucked deep within Tombstone Territorial Park, this hike takes you into a landscape that feels genuinely remote, where the mountains are jagged, the valleys are wide open, and the wildlife is very much present. If you're heading out here, come prepared and come with respect for the terrain.

The Setting

Tombstone Territorial Park is one of the Yukon's crown jewels, and Grizzly Lake sits well within its core. The park protects a dramatic stretch of subarctic wilderness along the Dempster Highway corridor, and the Grizzly Lake area reflects everything that makes this region so striking. Think angular peaks, open tundra slopes, braided creek drainages, and a stillness that's hard to find anywhere else. The lake itself sits in a glacially carved basin, surrounded by the kind of scenery that makes you stop walking just to take it in.

This is true backcountry. There are no manicured trails, no handrails, no interpretive signs along the way. Route-finding is part of the experience, and the terrain demands your full attention.

What the Terrain Is Like

The route to Grizzly Lake involves a mix of terrain types that are typical of the Tombstone backcountry. You'll move through open tundra, cross creek drainages, and gain elevation on slopes covered in tussock grass, loose rock, and low-lying shrubs. Tussock walking — those uneven, ankle-twisting clumps of sedge grass — is a real factor here and slows your pace considerably compared to a groomed trail.

The ground can be wet and boggy in lower sections, especially earlier in the season when snowmelt is still draining through the valley. Waterproof boots aren't optional here — they're essential. Higher up, the terrain transitions to more exposed alpine ground with talus fields and open ridgelines that offer sweeping views of the surrounding peaks.

Creek crossings are part of the route. Water levels vary depending on the time of year and recent precipitation, so be prepared to get your feet wet or scout for the best crossing point. There are no bridges.

Wildlife

The name says it all. Grizzly bears are active throughout this area, and sightings are genuinely common. This isn't a place where you carry bear spray as a formality — it's a place where you carry it loaded and accessible at all times. Travel in groups, make noise on the trail, and know what to do if you have an encounter.

Beyond grizzlies, the Tombstone backcountry supports a full suite of northern wildlife. Caribou move through the area seasonally, Dall sheep are often spotted on the higher ridges, and wolves are present in the park. Golden eagles and ptarmigan are common overhead and along the tundra slopes. The biodiversity here is tied directly to the intact, undisturbed nature of the ecosystem — treat it accordingly.

Planning Your Trip

Access to the Grizzly Lake area starts from the Dempster Highway, which is the only road corridor through this part of the Yukon. The Dempster is a gravel highway, and conditions can change quickly — a rental vehicle agreement that prohibits gravel road travel won't get you here. Make sure your vehicle is appropriate for the road, and carry a spare tire.

Tombstone Territorial Park requires backcountry registration for overnight trips. If you're planning to camp near Grizzly Lake, check in with Yukon Parks before you go. The park has a visitor centre near the Dempster Highway that's worth stopping at — staff there can give you current conditions, wildlife activity reports, and any specific advisories for the area you're heading into.

There is no cell service along the Dempster or within the park. A satellite communicator is strongly recommended for any backcountry travel in this area. This is not a place where help is close by.

When to Go

The window for hiking to Grizzly Lake is relatively short. Snow can linger well into June at higher elevations, and early fall snowfall can arrive in August. The prime window is generally mid-July through mid-August, when the tundra is in full colour, the days are long, and the alpine terrain is most accessible. That said, weather in the Tombstone Mountains can shift fast — pack for cold, wind, and rain regardless of the forecast.

Mosquitoes and other biting insects are intense in July, particularly in lower, wetter terrain. A head net and insect repellent will make a real difference to your experience.

What to Bring

• Bear spray — carried accessibly, not buried in your pack
• Waterproof boots — mandatory for creek crossings and boggy tundra
• Trekking poles — helpful on tussock terrain and creek crossings
• Satellite communicator — no cell service in the area
• Navigation tools — map and compass or GPS; no marked trail to follow
• Layers and rain gear — Tombstone weather is unpredictable
• Insect protection — head net and repellent for peak bug season
• Extra food and water treatment — for any unplanned overnight situations

Leave No Trace

The Tombstone backcountry is sensitive. The tundra vegetation grows slowly and takes years to recover from damage. Stick to rocky or already-impacted surfaces when possible, camp on durable ground, and pack out everything you bring in. Campfires are restricted within the park — check current regulations before your trip. The goal is to leave this place exactly as you found it, so the next person — and the wildlife that lives here year-round — experiences the same thing you did.

Grizzly Lake rewards the effort it takes to get there with a kind of wilderness experience that's increasingly rare — vast, quiet, and entirely on its own terms.
