Mammoth 77 Treehouse at Taylor Create Your Own Snowmobile Tour Zip through the snow on a " mountain sled " near Bear Valley's snowmobile-only winter village on Highway 4. Bear Valley Snowmobile will stage your machine at the trailhead, so all you have to do is bundle up and don your helmet. There's no need to join a guided tour-with a few brief instructions, even fi rst-time snowmobilers can hop on a sled, rev the engine, and safely cruise through snow-cloaked meadows and pine forests. If you'd be more comfortable with a guide showing the way, check out Snowmobile Adventures in Mammoth to enjoy mountain views while you cruise along tree-lined trails. 78 Ski to an Off-the-Grid Treehouse Immerse yourself in West Siskiyou County's backcountry with a remote overnight adventure.
