- Montana Mel from United States writes:
In the past few years, Big Sky has been discovered. No longer a sleepy giant, there are now lift lines. Maybe because Montana had the best snow in the USA in 2018, and maybe due to the addition of the Ikon pass; either way there are now lots more people; don't count on powder lasting beyond noon, where in the past it might have lasted for days. Lines are much shorter or non-existent in April, when sunshine can be intense. If you enjoy dining out, plan on a few trips to Town Center or Highway 191 on the Skyline shuttle for the best food.
