Part of the day will be in the mangroves and then you have some options for the rest of the day: 

• Egmont Key:  Explore Fort Dade built in 1898 during the Spanish American war, to prevent the Spanish from entering Tampa Bay. Also tour the Egmont lighthouse, first built in 1848 then rebuilt in 1858 after damaged by a hurricane. Egmont beaches are a beautiful place for a picnic, shell picking and swimming. 

• Passage Key: A small sand bar south of Egmont key. a great place for just lounging in the beautiful water. 

• Dolphin Watch: Finding dolphins in their natural environment. A fun thing to watch. 

• Shell Key: Another great place with beautiful beaches for picnics, swimming and shell picking.
