If you like seafood then the Keys have a number of places you can eat.  But be careful, a lot of places serve mostly fried food so check out the menu before you decide on a spot to dine.

There are 42 bridges connecting the Florida Keys to each other, and to the mainland, in fact 15% of your time driving down to Key West will be over bridges. The longest of the lot is Seven Mile Bridge which connects Marathon with Bahia Honda.

This small State Park can be a popular place, what with a handful of short trails, fishing, kayaking/canoeing, boat tours and even a little beach.  There's a store where you can book activities, buy trinkets and pick up some refreshments too.

We recommend the kayaking if you're up for it.  Cruise around the mangroves casually at your own pace with hourly rentals, but remember to bring a change of clothes and some sunscreen because you're liable to get wet and burnt otherwise.

The Florida Keys are well known for their small limes, and if you're looking to sample the local product, then you'd be hard pressed to go past this place.  Between Key Largo and Tavernier (if you're heading south), this store stocks everything from marinades and dressings, to Key Lime soda and sweets.

If you happen to see a giant lobster on the side of the road, then you might want to stop and check out perhaps the Keys' finest collection of artisans. A variety of styles and materials are employed in this fairly extensive collection of arts and crafts for sale to the public.

The Wild Bird Center is free to visit, though there is a donation box for those who want to leave something.  If you've ever wanted to get up close with pelicans, egrets and herons, then this is the place.  The center attracts several species with their regular feedings, and also has a number of enclosures for rehabilitating hawks, owls and various water and shore birds. 

There's even a couple of parrots up the front who'll be happy to talk to you, or cats who'll be happy to be petted.  Definitely worth a visit if you've got the time.
