Historic Blue Marlin Fish House is located on the site of the original Blue Marlin Smoke House, circa 1938, owned by the Diefenbach family. Back then it was a smoke house and a trading post where fishing captains could dock their boats and barter their catch.
In January of 2005, the Blue Marlin Fish House was reopened by Florida Parks and awarded to Blue Moon Outdoor Center.
Guests can enjoy views of the Oleta River while tasting smoked blue marlin, salmon, and mahi-mahi that can be served as a sampler, as sandwiches, or on salads. Smoked fish dip is a Fish House favorite as well. Chicken, burgers, hot dogs, and other items are available for landlubbers. Microbrew beer, domestic beer, and wine are also on the menu.
An Intrepretive Center displays the rich history of the area as well as the plant and animal life at Oleta River. The Tequesta Indians inhabited this site 3,000 years ago.
