Chappaquiddick Island is located adjacent to Martha's Vineyard island, but only a short (1 minute) ferry trip away. The ferry can be accessed either by foot, bicycle or car. However, if you wish to explore past the beach at the ferry port, a car or bicycle is definitely needed.
One of the highlights of exploring this secluded island is seeing Mytoi Garden. This garden has a Japanese style and is very peaceful to walk through. In the lake in the middle are snapping turtles and there are various forms of botany in the garden. This is a place that doesn't get as many visitors as it deserves due to its seclusion, but because of that, it makes it a better place to visit and is highly recommended.
