Visitor Reviews of Moonlight Basin
- CASA Tours from United States writes:
Moonlight Basin has some of the best in-bounds terrain in the United States. The Headwaters Traverse - aka the Lord of the Rings Traverse - accesses a plethora of steep, interesting terrain. The traverse alone gets the adrenalin juices flowing. The Spring Run-Off Challenge is one of the few big mountain free ride competitions in SW Montana. With a Lone Peak Pass skiers and snowboarders can ride both Big Sky and Moonlight, which means access to the North Summit Snowfield, one of the longest runs in North America, over 4000 vertical feet. Moonlight's patrol does an amazing job in getting their terrain open and really encourages folks to get after it. Moonlight is also an ideal place for families and beginners. With little to no crowds ever, Moonlight has lots of space to cruise. The only downside are some flat sections on the lower mountain. If you are looking to bang out laps the Headwaters chair and the Lone Tree Lift allow one to rack up vertical quickly. Moonlight has a cool local scene and offers a cheaper alternative to neighboring Big Sky. For apres the Moonlight Lodge is a classy place where you can still get a PBR and plate of Nachos on a dirtbag budget.
