Nice park with a beautiful beach
Bight Park is a wonderful community park with a small botanical garden describing many of the local plants you can find on the island. There is no entrance fee and usually plenty of parking, bathrooms and some picnic tables. If you're in to large crowds and loud music you can attend the Thursday night Fish Fry (which has a lot more than just fish available to purchase). This event is also free admission.
Make sure to put it back so that it is hidden from view.
