I have been to Wintergreen Resort countless times (I used to live in the area). Wonderful place for outdoor activities. It has 2 great and vastly different golf course, numerous outdoor tennis courts, a huge indoor tennis complex, miles upon miles of trails (from easy 1 milers to more streneous 10+milers), a lake with canoeing, bicycle rentals, outdoor and indoor pools, etc. (skiing in the winter as well). The whole place is just very serene and has a lot to offer. The dining options are limited, but several are very good. The vineyard is also worth a visit.

PM me if you have any specific questions.
