Powder house hill is the closest just up in North Berwick, Me. This is a very small ski hill reminiscent of the way skiing used to be all over New England.
If it was me I would be more interested in driving to Cannon, Wildcat, Bretton Woods, Attitash, Cranmore. You can google them and see if any of them strike your interest. These will take you 2 to 21/2 hours allowing for dry roads and obeying the speed limit.
