Mount Sunapee covers 232 acres (94 hectares) with 66 runs near Newbury, New Hampshire, inside a state park. It rises from about 1,230 ft (376 m) to 2,740 ft (836 m), a vertical of 1,510 ft (460 m). The split is 30% beginner, 46% intermediate, 11% advanced and 13% expert, an unusual shape with more expert than advanced terrain. Snowfall averages around 99 inches a year. The mountain is organised into five areas, each with a slightly different personality, from open cruisers to a separate learning zone.

The Main Face has intermediate cruisers, while Sunbowl, reached from the North Peak triple via Upper Cataract, adds lake views. North Peak holds most of the advanced terrain, and Spruce Peak is home to the terrain parks, including the Six O' Three Terrain Park. Lynx, Skyway, Goosebumps and Flying Goose are among the named runs, and South Peak is a separate beginner area. Sunapee suits families, intermediates and park riders, while experts looking for sustained steeps will find North Peak the best of a small supply.

The 2025-26 season at Mount Sunapee ran from 6 December 2025 to 5 April 2026, a roughly seventeen-week season supported by average annual snowfall of around 99 inches. Excellent snowmaking, a point of pride for the resort, supplements natural snowfall to maintain consistent, well-groomed conditions throughout the season.

Midwinter, from December through February, typically brings the most consistent conditions to Mount Sunapee's intermediate-and-beginner-weighted terrain. As an Epic Pass resort within the Vail Resorts network, Mount Sunapee draws substantial visitation from Epic Pass holders, supported by its roughly 90-minute drive from Boston, one of the more accessible major resorts for that metropolitan area.

The resort's reputation for Vermont-quality conditions within New Hampshire continues to draw visitors seeking a shorter drive without sacrificing terrain or grooming quality. School holiday periods bring substantial family visitation given the resort's varied terrain and family-friendly amenities. Weekend crowds draw heavily from the greater Boston region.

Specific event programming beyond standard operations is not confirmed in available resort information. Since Vail Resorts' 2018 acquisition, Mount Sunapee has continued operating under its distinctive state park lease structure, a model dating to the Mueller family's landmark 1998 agreement. The resort's blend of state park setting and private operation remains central to its identity each season.
