Half Day Trips We offer two half day trips that are five hours. The morning half departs at 7:00am and returns at 12 noon. Afternoon trips leave at 12:30pm and return again at 5:30pm. With the blue waters of the gulf stream only a few miles off the coast of Key Biscayne the possibilities are endless. There have been many bountiful half day trips on the L&H including one December day when a father and son team combined to catch several large kingfish and 24 sailfish fishing in front of the Key Biscayne hotel where they were staying!
