Full Throttle - View this location on map 'Even if you have never piloted a snow machine, you can rev it up with Telluride Snowmobile Adventures (970-728-4475). The hardest part is keeping your eyes on the groomed track and off the jaw-dropping views of the Ophir Needles and Palmyra Peak. A two-hour tour includes laps in Magic Meadows and a visit to the well-preserved ghost town of Alta. Guides point out the miners' bunkhouse and the steam shack and offer historical nuggets about the town's mining days. The cost is $130 for a single rider, $180 for two.''
