Snow Hikes With Dogs in Mammoth Lakes (Winter Trail Guide 2026)

Winter in Mammoth Lakes might be the most overlooked season for dog hiking in California. While the Lakes Basin is packed with visitors during the summer, winter transforms the area into a quiet, snow-covered playground of forests and trails where you and your dog can wander for hours without seeing many people.

Quick Answer: Winter Dog Hike Options

Shady Rest Park — The Winter Dog Hiking Hub

Shady Rest Park is the most reliable winter dog hiking destination in Mammoth. The park's trail network stays walkable in all but the deepest snow years, and the forest setting is magical after a snowfall. The XC ski trails through the park are groomed in winter — dogs are welcome on the outer forest paths. Stay off the groomed ski tracks. Stick to the ungroomed outer loops for the best dog experience.

Forest Roads North of Town

The network of forest roads north of Mammoth Lakes (accessed via scenic loop) are unplowed in winter and completely open to walking and snowshoeing. Miles of quiet pine forest walking without trail fees or crowds. Most roads are wide enough that you don't need snowshoes unless the snow is deep.

Frequently Asked Questions

Do I need snowshoes for winter dog hikes in Mammoth?

On packed or consolidated snow, regular winter boots are fine. On fresh deep snow or off-trail routes, snowshoes make a significant difference for the human — your dog naturally floats better than you do. For the most common winter routes around town, snowshoes are optional.

Is it too cold to hike with a dog in Mammoth winter?

Most healthy adult dogs with medium or long coats thrive in Mammoth winter temperatures during daylight hours. The sweet spot is 20–35°F with low wind. Below 10°F with wind, limit exposure for short-coated or small breeds.

Are the Lakes Basin trails accessible in winter?

No. Lake Mary Road is closed in winter. The Lakes Basin trailheads are under significant snowpack from November through May. Winter dog hiking in Mammoth is focused on town-adjacent areas: Shady Rest Park, the forest road network, and lower. That being said, you can hike on the left side of the road, the right is reserved for nordic skiers and is groomed.
