Sanibel Island is bike-friendly with bike paths that criss-cross the island. Bikes are necessary because parking is limited at places like the beach and even restaurants. We rode bikes for about 2 1/2 hours and it though I loved every minute, I can tell I need to do a little more bike riding to get in better shape - Scott's used to it because of his weekly workouts. In spite of the heat and humidity, we thoroughly enjoyed the scenery - the shops, homes, and neighorhoods around here are fun to look at - especially the close-up views we got on the bikes.
