Snowmobile tours are one of the most popular winter activities in the Vail Valley. Tours can range from simple "track" trips to powder-hound off-trail adventures. A snowmobile is a land vehicle propelled by tracks at the rear and skis at the front for steering. Snowmobiles (or "sleds") can be ridden single, or with two passengers. Because of the varied terrain in the Vail Valley, many adventures are available. Some tours are ideal for the whole family. Others, due to the physicality of controlling the sled in varied conditions, are reserved for the more seasoned snowmobiler. Tours are offered in full and half day formats. Most vendors offer food and hot beverages, but check with yours to be sure. Many offer snow suits and helmets, but be sure you are prepared for the elements (with similar attire to what you would wear skiing) in case they do not. See "What to Wear - What to Bring"
