Getting there & away
The only way to get to Isla Mona is by boat. It is highly recommended you go with a professional and experienced guide as part of an organized trip. A number of people have actually died on the island after getting lost or becoming stranded (usually through dehydration).
All of the tour operators listed earlier run regular trips, although there are rarely set schedules. Prices vary depending on the length of trip and number of people. Phone ahead for a quote. Visiting Mona requires advanced planning. Don’t expect to turn up on the west coast and leave the next day. If you are prone to seasickness, beware, the Pasaje de la Mona makes for a rough crossing.
