Lake Mary Road is closed just above the turnoff to Tamarack Lodge after the first major snowstorm of each season. For the rest of the winter, access to the Lakes Basin is only by snowshoes and skis. The groomed trails network includes fee-based cross-country ski trails as well as the Winter Access Corridor - Lakes Basin public-access right-of-way. On April 17 of each year, after the cross-country ski season ends and before roads are plowed, snowmobiles are allowed in the Lakes Basin on existing roadways only, conditions permitting.

Avalanche Forecast for 03/20/2023
- AVALANCHE FORECAST: Very dangerous avalanche conditions exist this morning where the most new snow has fallen, especially around Mammoth. Traveling on and below wind-loaded terrain is not recommended. New snow could be sensitive to human triggers and could shed as wet snow avalanches as the storm clears. Avalanches breaking in new and drifted snow could step down to deeply buried weak layers resulting in a much larger slide. Conservative decision-making will be essential for safe travel, even outside of the Mammoth area today. Find out More
