Besides wandering through the uninhabited northwest of the island, a popular hike is to head up to the lighthouse that offers a spectacular view of the entire island. The trail up is located off of the inland north-south path, a little south of the baseball field. It's not a particularly long or strenuous hike and the best time to do it is near the end of the day so you can watch the sunset. Don't forget to take a flashlight.
