I can guarantee you a good time and you'll see some sharks if you go out boating in the Florida Keys! All you need to do is use the kayak, but I have to admit the motorboat is very entertaining. We went out last weekend from the West Card Sound Ramp at mile marker 110. This is a one lane single boat ramp on the west side of card sound bridge. It is nice being in so much nature, and this is pretty remote for some people. Perhaps a better choice for families and those with children with a boat, go down to the Caribbean Club Ramp at mile marker 104. Perfect for any boater is a double lane launch access next to the bar at 104075 Overseas Highway, on the bayside of us1. The kayak rental place is right next-door. Very popular is the Pennekamp Boat Ramp. This is a very nice park area at mile marker 102, which has a big marina and four modern lanes. All of the boating facilities are inside the Coral Reef State Park. The Caribbean Drive Boat Ramp in the middle of the Key Largo marina is a sweet boat ramp and dockage area. Guests of the Marina del Mar get access or you need to make arrangements with the dockmaster.
