Blackcomb is opened till April 25th, Whistler is open till June 6th. then the glacier (at the top of Blackcomb) is open until August 1st. opens up again on November 22nd. i'm really looking forward to glacier snowboarding in 20 C weather this summer...
there is some crazy terrain up here, and i'm just learning my way around. the place is HUGE.
conditions are pretty much always great. and if you want easily accessible extreme, this is the place to be
edit: 'couloir extreme' is usually accessible until August 1st.
