This is a longer tour so you get to see most of the island. You also have the freedom to get on and off the carriage and choose how long you spend at each stop. Get your tickets early as the lines will get long or buy tickets in advance.
Biking is a big hit on the island. You can actually bike all the way around the island in an hour or stop and explore along the way. The bike trail takes you around the perimeter so you are riding along the water on a safe paved path. Are you a mountain biker? They have special trails for that too!
