I don't think you'll get much freshwater fishing in that area, but there is a lot of fishing done from the Sabastian Inlet just north of the resort. I'm not sure if you have to pay to get into the Sabastian conservation/park area but I've seen a lot of folks with kids fishing from that area with rods as you get a lot of fish in the chanel between the ocean and the intracoastal waterway.
