Mount St. Louis Moonstone, one of Ontario's most celebrated ski destinations, is expected to kick off its 2025-2026 season with an opening day that combines snowmaking magic, natural flurries, and eager anticipation.

Why Mount St. Louis Moonstone Stands Out

Located just north of Barrie and within easy reach of the GTA, Mount St. Louis Moonstone is more than a ski hill—it's a cornerstone of Ontario winter culture. Whether you're a seasoned skier, first-timer, or weekend cottage-goer looking for winter adventure, this resort offers something for everyone.
