The MOHONK MOUNTAIN HOUSE is a historic American resort hotel located on the SHAWANGUNK RIDGE in Ulster County, New York.

The historic resort is located on the shore of LAKE MOHONK, which is half of a mile long and 60 feet deep. The main structure, which is designated a NATIIONAL HISTORIC LANDMARK, was built by Quaker twin brothers ALBERT and ALFRED SMILEY between 1879 and 1910. It has 266 guest rooms, including 28 tower rooms, an indoor pool and spa, and an outdoor ice-skating rink for winter use.
The property has been owned and operated by descendants of the Smiley brothers since 1869. It consists of 2,200 acres and much of it is landscaped with meadows and gardens.
