You can also bring your own bike over on the ferry for about 7 dollars. Take your time when biking around the Island. The beauty is breath taking. The air is fresh and crisp. There is a rest stop about half way around. You can use the restroom or purchase ice cream, hotdogs and other snacks. You can also pack a picnic lunch and stop along the way. There are picnic areas for you to enjoy. It is a easy ride. The road is very flat with the exception of just a couple of spots where you will need to pedal with some effort.
