I know, I know. Everyone is excited for bike season. I'm the opposite; I don't want to see ski season end! Luckily for me (and other weirdos like me), there are a couple ski resorts open in May. Here are a few places you can get those last few turns in:
Loveland has easily the best skiing in May. Thanks to their high elevation, they are able to keep most of the mountain open until their closing day. Every year, they close on the second Sunday of May (this year will be on May 7). So if the conditions are so great, why do they close so early in May? According to a ski patroller I met on a chairlift, their closing has nothing to do with the snow conditions. They close on this weekend every season due to the grouse migration in the area.
Winter Park has two distinct sides of the resort: Winter Park and Mary Jane. While the Winter Park side closes every year in late April, Mary Jane is a free-for-all. Although they don't have a closing date yet, they will be open "as late as possible" according to staff. They have closed mid to late May for the past couple of seasons. With all high-speed lifts running, Mary Jane is THE place to go for mogul laps on repeat
If you want the longest single-run vertical possible, Breck's May experience is the place to be. The Imperial Chair is often open until closing day, which allows you to cruise from top to bottom for a sweet ~3k vertical. Breck is expected to close around Memorial Day weekend, though this closing date has been historically iffy.
A-Basin boasts the longest season for Colorado every year. If May skiing isn't enough for you, they are (just about) guaranteed to be open into June. A-Basin keeps their event schedule stacked throughout the end of season, so there is always a party to enjoy. If you want to party hard like Andrew W.K., then A-Basin is a can't miss!
