Bear Mountain's south, east, and north sides contain the Topridge, Northwoods, and North Side areas, respectively. The Northwoods Area is the lower mountain and base trail area, wholly containing the Northwoods Gondola. The Northwoods area is also served by the Adirondack Express II, a newly built high-speed quad chairlift (built in 2014). It replaced a high-speed triple chair built in 1984, which was the only high-speed triple in the eastern USA. The AEII While the gondola reaches the summit of Bear Mountain, the quad reaches slightly below this to an area called the Saddle (where the Saddle Lodge is located), providing access to most of the Northwoods and all of the North Side. A double chair also serves the southern part of Northwoods, along with several surface lifts around the base. Twister, an intermediate trail in Northwoods, is the resort's longest run and most-used racing course. The North Side is served by a quad and contains several easier trails. Additionally, it provides direct access from the Saddle to the High Peaks area (via Lower Wood In) and North Creek Ski Bowl (via Pipeline). The Topridge area is served by a triple. Its most prominent trails are Topridge, Uncas, and Pine Knot, the latter two of which are heavily used as connecters from the Bear Mountain summit (the top of the gondola) to the Straight Brook Quad. The Cave Glades, located in the Topridge area, are named for a large cave found along them.
