Maybe a bit optimistic!!
Bansko has a good snow record (end April still OK) but with the biggest snowfalls seen for years is there any chance you could ski in May.
I know I could check the snow record but this year is unprecedented.
Has anyone got any first hand experience of the this amount of snow, and how long it could last!
Just returned from there, local oppinion is should still be up and running till then. If you want a local snow report, give the brits who run the Devonshire Lodge a call. They'll give you an honest answer, and they offer a very good service, if your looking for somewhere to stay.
