Lake Mary is the crown jewel of the Mammoth Lakes region, and a busy year-round destination. In the summer, you can ride here via the aptly named Lake Mary Road, or via the paved Lake Basin Bikepath. The road and path are not maintained during winter, but the lake is still accessible via snowshoe and cross-country ski trails

Mammoth Mountain Resort is a premier destination for skiing & snowboarding. However, the resort and its surrounding area also have plenty to do throughout the rest of the year. If you don't have a bike there are plenty of places to rent from so you can take advantage of the many miles of road and trails. If you ever need to meet up with someone just say you'll find them at the iconic Mammoth statue and you won't have any trouble finding each other.
