Excellent ski area. Lots to do on mountain and Bethel is the quintessential New England ski town. Not a lot of amusements but so much local culture that you really know where you are. There is fantastic dining choices but you may need a car to reach the furthest. There is a local bus service loops every 15 minutes and takes visitors from all over the mountain and downtown. For a really relaxing weekend or vacation it’s a great place to visit. Conditions at Sunday River exceed all else in the area as their award winning snowmaking and grooming is the best in the USA.
