Great terrain variety, grooming, glades
Not a big name resort (so you can't brag to friends about it)
Not sure what some other reviewer(s) are talking about in regard to lack of beginner terrain. The lower mountain pod is all beginner terrain (serviced by a high speed quad!) that also has some excellent progression terrain parks thrown in for variety. The trails on this part of the mountain are about 3/4 of a mile long and there is even a beginner glade.
Please be wary of reviews of ANY New England ski resort from December. December can become a feast or famine for snow conditions overnight. That said, Burke has an adequate amount of snow making to get most trails open by mid-December just like any other major ski area. However, given Burke's northerly Latitude it does not have to depend on a huge snow making system to keep the mountain skiable. By late December, the natural terrain is usually open and skiable with excellent natural coverage (glades included). The natural terrain will typically stay open for the remainder of the season. Natural coverage, old New England style cruisers like East Bowl are a lot of fun (except for the run out :) .
Burke also does an excellent job with its groomed terrain. Cruisers like Dippers and Willoughby are outstanding for their snow quality, exciting rolling terrain, and great views of northern Vermont.
Don't let the extra drive time deter you (It is only an extra 40 minutes past the Ski-93 areas in NH). That extra 40 minutes is quickly made up for with very short (usually no) lift lines. Spend your time skiing, not standing in line (unless you really like standing around in line).
For expert skiers, Burke has an outstanding glade system. Long steep rolling glades like Jungle and Dixieland will have your quads screaming by the time you reach the bottom. Resorts like Jay Peak are well known for their glades but I think Burke is in the same class in this department.
Sure Burke is not a big flashy name that you can go home bragging to your friends about since they will probably reply "where's that". But come give it a try. All through January this year I skied on Saturdays and NEVER stood in a line and there was not a patch of ice to be found on the mtn. There is live music in one of the two lodges every night during the weekend and on some weekdays as well. Bring the family, there is something for everyone.
