Isla Catalina Diving is located 45 minutes from Punta Cana and 1.5hrs from Santo Domingo. It is very easy to get there, taking the Autopista del Coral exit Casa de Campo, direction city center La Romana, passing the entrance of Casa de Campo and in 900 meters - before crossing the bridge - turn right. Follow the route for 200 meters under the bridge and turn right immediately after crossing the train rails. You will see Isla Catalina Diving just in front.
