Balsam Lake Mountain is one of the Catskill Mountains, located in the Town of Hardenburgh, New York, United States. It is the westernmost of the range's 35 High Peaks. Its exact height has not been determined, but the highest contour line on topographic maps, 3,720 feet (1,130 m), is usually given as its elevation. Located within the Balsam Lake Mountain Wild Forest management unit of the Catskill Park Forest Preserve, in the late 19th century its summit became the site of the first fire lookout tower in the state, operated by members of a nearby sportsmen's club. It was later taken over by the state's conservation agencies, which built several improved towers on the site, one of which remains, along with its accessory buildings and has been listed on the National Register of Historic Places, although it has not been used for fire detection since 1988. The summit is also the site of a rare sphagnum bog that has been affected by acid rain since a mid-20th century windstorm blew down many of the trees sheltering it at the time. The tower and the views it commands, as well as its ease of access by the old truck road to the tower, have made it a popular attraction for hikers despite the mountain's remote location.

The Balsam Lake Mountain Fire Observation Station is located at the summit of the mountain of that name in the Town of Hardenburgh, New York, United States. It comprises a steel frame fire lookout tower, the observer's cabin and privy and the jeep road to the complex. Balsam Lake Mountain, the westernmost of the Catskill High Peaks, was the site of the first fire lookout tower in New York in 1887, when a nearby sportsmen's club built it to protect their lands below the mountain. It was later taken over by the state, which built several towers culminating in the current one. The tower was staffed until 1988. After being closed for much of the 1990s, the tower was proposed for demolition as one of five remaining on state-owned Forest Preserve land in the Catskill Park. Hikers and local residents rallied to save it, and after the state's Department of Environmental Conservation changed its mind, it was restored and reopened. It was added to the National Register of Historic Places in 2001, the highest-elevation property in Ulster County to be listed.
