Onteora Club is in an idyllic spot, where residents and members enjoy the rugged beauty of the natural surroundings. There are more than 80 cottages; a field house for dining, bar, overnight accommodations, special events and art exhibitions; a library with active programming and readings throughout the summer; as well as a multi-use theatre, where children and adults perform two plays each season, and for seasonal live art and musical performances. Onteora has a beautiful sports house with pro-shops, five clay tennis courts, a private historic 9-hole links-style golf course, and trail center. The Club also boasts a heated pool, lake and beach, miles of hiking trails, and a trap-style gun club.

Onteora enjoys a close affiliation with the All Souls Church and Mountain-top Arboretum, just outside its gates.
