Lost Tree Club was developed in North Palm Beach beginning in 1961 by Edwin Llwyd Ecclestone Sr. as one of the early high-end gated oceanfront communities, carved from former mangrove swamp and beachfront. The golf course was originally designed by Mark Mahannah. Jack Nicklaus, who made Lost Tree his longtime home club after moving there in 1965, directed a roughly $6.5 million course restoration completed in 2002.
