Yes if you are settling here for a season or more — take the trial lessons before paying the $500 initiation, and pin down how many you get, because the club's own page says two in one paragraph and three in the next. Skip it if you only want one ride.
Sagaponack
Topping Riding Club
Full membership required, often with own horse, by invitation or waitlist.
Private members' club on 25 acres about a quarter-mile from the beach, on the corner of Daniels and Gibson Lanes. Year-round riders pay monthly dues plus a one-time $500 initiation fee, with trial lessons available before you commit — the club's own page says a maximum of two in one place and three in another, so confirm when you book. Teaches basic dressage, jumping and hunt-seat equitation from age 3 up, offers full board and dry stall leases, runs a nine-week summer pony camp in morning and afternoon sessions, and hosts the two Sagaponack Horse Shows on the third Wednesday of July and the second of August. Beach rides are for members riding their own horses.
