Cas En Bas always has a stiff breeze, which makes it an excellent kitesurfing spot. There are a couple of kite places located here but they're not always open so reserve in advance.
There are a number of stables in the area offering trail rides as well as beach canters along Cas En Bas beach. Expect to pay US$65 for two hours. Free pickup services can be arranged from most hotels in the Rodney Bay area. Children are welcome.
