Welp,

Looks like my family wants to go to Vail for this year's trip out west. It will be the first week of April. Are they usually still fully open (including the back bowls) during that time? The pros and cons of Vail have been discussed here and elsewhere but if I am going to go I do want to be able to take advantage of its full terrain.

I've been a dozen times, many of which were in April.  Never seen it less than full open.  During late season there's a higher risk of non-groomed terrain being not ski-able due to daytime warming and overnight freezes. My first time there was Thurs-Sun of closing weekend 2008 when it snowed ~30", yeah a couple chairs were on wind/snow holds.  Some crazy vertigo happens in those bowls during whiteouts.

April scares me.  Groomers maybe not as much, but for powder?  Check their avg snowfall for the month.

Also many orgs start shutting down that last month of being open, which for vail is the month of April.  

Heck home depot/lowes start putting out lawn equipment a couple of days before xmas.   My local hardware store is sold out of all their snow throwers for the year.  And the snow has yet to really begin.  

Would I turn down the opportunity to go to Vail in April?  Heck no!
