Running approximately half the length of Half Moon Cay, Bonefish Lagoon measures just over 280 hectares (700 acres). This protected saltwater bay is where Holland America Line offers many of its water sports activities on the island, including kayaking and the Aqua Trax Adventure. Since it’s encircled by the island on all sides except for an entrance to the sea at its northeastern corner, the water here is calm, making it an ideal place for novices to try out a new activity. As for its name, there’s a population of bonefish here, and fishermen can cast a line to land one.
