North Caicos is located in the Caribbean.
You will have to rent from a private vehicle provider. Usually there are rental car representatives at the dock where the ferry lands.
There are several beautiful beaches including the easily accessible Horse Stable Beach and Three Mary Cay which is down a minimally maintained road but well worth the visit. Bring your snorkel gear- there is a submerged wreck that is covered with coral and pretty fish.
North Caicos has a great fishing industry and due to their position have an assortment of fishing available (deep sea, bottom fishing, fly fishing, etc)
Drive over to Middle Caicos.
