While Mirkwood Basin at Monarch is open for hikers to get their backcountry turns in, the best way to travel is definitely by Snowcat. Monarch Snowcat Tours is sponsored by K2, BCA, and Smith which helps the luxury of the ride. Twelve skiers can fit (very comfortably) in the back of one Cat as Sirius Satellite Radio pumps through the speakers and cushy leather seats absorb the bumpy ride.
