We will be arriving at Puerto Limon on a cruise ship in mid December. Is there public transportation near the port to Chauita National Park? Are taxi's by the port? At the park back to the port? If so, what might I expect for a price? Is there transportation from the park to the village of Chauita? Are there tour operators in Chautia to the park that may have a snorkling tour? We port early and need to be back on the ship by 3:00. I don't know if this is something we can do on our own or if I really should book a tour through the ship or a tour operator in Limon. Any suggestions, information, or advice is appreciated.
