The hotel covers 11,000 acre and features 95 kilometers of cross-country ski trails, an alpine ski area with 16 trails, five glade areas and a terrain park.  There is also a 9-hole golf course and an 18-hole championship course called "Panorama" which was designed by Donald Ross.  As of 2017 The Balsams is closed for renovations after being purchased by new owners for $2.3 million in December 2011.  In 2014, former American Skiing Company head Les Otten joined the Balsams redevelopment effort.  Included in Otten's current plan is a massive expansion of the ski area to around 1,000 acres and the addition of multiple lifts, including a year-round gondola to the summit and a lift connection across Route 26 to the hotel complex.
