Osheaga is one of the best things to do in Montreal during August, full stop. It's a summer staple—part music festival, part muddy rite of passage. With 55,000 people pouring onto Île Sainte-Hélène each day, it’s a three-day marathon of heat, headliners, and hydration anxiety.
Olivia Rodrigo. Tyler, the Creator. The Killers. Jamie xx. DoeCHii. If you're anywhere near Montreal, you already know what's coming: Osheaga weekend. Three days of music, mud, overpriced drinks, and unrelenting vibes on Parc Jean-Drapeau—and you either prep smart or get swallowed whole.
This guide is for the real ones: First-timers, seasoned pros, the ones debating whether to break in those new Docs, and the ones who forgot deodorant last year and paid the price. Here’s everything you need to know to survive (and maybe even enjoy) Osheaga 2025.
