It depends on the season but were in Whistler end of March/start of April last year and 2011 and the conditions were great. Lots of snow.
Lots of snow in the alpine and glades.
Some days were foggy and we hit the glades, but on bluebird days the alpine was great. Some of the best terrain parks we have seen although we are just learning park. They had a mini-pipe and a super pipe.
It was fun at the end of the day to go down the village from the alpine because as the temperature increased we would go from riding powder to slush to icy/packed powder back to slush at the village. It made for a fun last run before hitting the bars.
Great spring riding for sure. And the mountain was 100% open except on those days when it was windy or there was a big storm and they close the alpine.
The picture was taken in Whistler in April.
