Here is a fun idea for a day on Lemon Bay. Gasparilla Boat Tours has daily eco tours. Every Tuesday they host a cruise through Lemon Bay, so you can learn all about the ecology of the area, and then stop for a delicious lunch at The Lighthouse Grill at Stump Pass. This is definitely worth checking out.
If you are looking for a great place to spend Happy Hour, come on down to the Lighthouse Grill. We have the best view of Lemon Bay and the Sunsets are spectacular!
