Best Things To Do In Suffolk County

  • Oheka Castle

On the top of the list of best things to do in Suffolk, NY, is a tour of Oheka Castle. Also referred to as Long Island’s castle, this sprawling estate was built in the middle of a 443-acre plot of land situated on the highest point on Long Island in Cold Spring Harbor. 

The estimated cost to build at the time was $11 million or $158 million in today’s currency. When this French-style Chateau was constructed, it was the second-largest private residence built in the USA and still is to this day. During the roaring twenties, the owner Otto Kahn used the 109,000-square-foot, 127- room estate as a summer house for lavish parties that hosted royal guests, heads of state, and Hollywood movie stars. 

Unfortunately, after Mr. Kahn’s death, ownership of the estate changed hands several times, each time taking its toll on the estate’s condition. Lucky, in 1984 a developer, Gary Melius, purchased the castle and the remaining 23-acres and began restoring the beautiful estate with help from architects, historians, and researchers. Years later, after completing the $40 million renovation project, the Oheka Castle is listed on the National Register of historic places and is a member of several historical groups. 

The Oheka Castle is now a hotel and estate and features guided mansion tours and a restaurant. The guided tour takes you through public areas of the estate and gardens, followed by refreshments of coffee or tea and a variety of Castle-made cookies from the pastry kitchen. Or if you prefer to get lunch after your tour, you can always visit the OHK bar and restaurant.
