The Verdict

Big Sky is significantly larger with 3x the skiable terrain, making it ideal for multi-day trips where you want variety without repeating runs. At 11,166 feet, Big Sky offers a true high-alpine experience with better snow preservation. Your pass matters here: Sun Valley is on Epic while Big Sky is on Ikon. Check which you hold before booking. Consider your priorities: terrain size, snow quality, or convenience. Each factor may point to a different choice.
