The month of May starts the run of big spotted sea trout in the St Johns River. These fish are very aggressive and are a blast to catch on artificial lures.
Jacksonville has a incredibly diverse fishery, with the downtown riverfront area being one of many options. Afternoon, evening and night trips are available for persons who may have meetings and business during the day. I live 2 miles from the the Jacksonville Landing and downtown hotels which allows me pick up my anglers by boat right next to their hotel.
