The City received multiple Waterway Assistance Program grants from the Florida Inland Navigation District to design and develop a waterfront park with a boat ramp, fishing platform and picnic facilities which opened to the public in January 2020. The boat ramp, located off North Main Street right before the county line, provides water access to the upper stretches of the Nassau River while the fishing platform has become a popular spot with anglers and the picnic shelters provide impressive views of the expansive tidal marsh. Accessible amenities includes the fishing dock and boat ramp. Additional features: Get Directions Get Directions Amenity Count Boat Ramp Picnic shelters Fishing Restroom Parking Lighting
