Early or mid-April should be fine. The snow runoff doesn't begin in earnest until May, usually, and you'll find warm weather, sunny skies, and great corn snow skiing (some of the deepest snowpack of the year can usually be found in early April). Unless you get lucky, don't expect powder, but you don't need powder conditions to have a blast.

I am planning to go in Easter but I am afraid to find wet snow or little snow, the prices are better and are there a lot of offers, any suggestion, I know it will depend but when is the latest you estimate I should go.
