What to pack for your Cocos Dive Liveaboard?

Soft luggage is recommended as it takes up very little space when empty.
Sunscreen, sunglasses, a visor, raincoat, lightweight sweater or jacket, long-sleeved shirt, backpack, tevas/sandals and a hat are recommended.

All linens (including sheets, comforters, bath towels, hand towels, dive towels) are provided on board.

Getting to Costa Rica & Baggage Restrictions

You must arrive at least one night prior to the departure date.


Costa Rica has two international airports. For optimum convenience, we recommend that you fly directly to San José (SJO) rather than the more distant Liberia International Airport. 


Pack lightly since you will be dressing for warm tropical weather. Please check with your airline for weight allowances and baggage policies. Airlines have ever-changing baggage limitations that can affect divers and photographers, so always check for updates on regulations.


Currently, Costa Rican customs places no limitation upon entering the country with personal equipment such as diving gear, cameras and video equipment or even computers meant for personal use. However, we do recommend that if you are carrying excessive amounts of equipment or professional gear, you simply declare that gear to customs.


All passengers must have a valid passport to enter Costa Rica. Most U.S., Canadian, EU and Japanese citizens do not require a visa. If in doubt we recommend checking with the nearest Costa Rican consulate to see if you will need a visa.


Please note, if you are traveling to Costa Rica from some South American countries then you will need to have a yellow-fever vaccination prior to traveling in order to enter Costa Rica.

Arrival in San Jose

Upon arrival in San Jose, you may take a taxi to your hotel. There are always taxis available at the airport and minivans for those of you who have a lot of gear. We can also arrange for your airport pickup as well as for accommodations at several fine hotels in San Jose. The night before departure, an Undersea Hunter/Galapagos Shark Diving representative will inform you at your hotel of your precise pickup time for transport to our dock and your awaiting vessel. Please note that we only pick up from a set list of San Jose hotels to go down to the vessels. The evenings on shore are at your leisure. Hotel nights and meals before and after the cruise are not included in the charter.

Transfer to the vessel

Please note that we only pick up from a set list of San Jose hotels to go down to the vessels. On the day of departure to Cocos, generally between 8 AM and 1 PM, you will be picked up from your hotel and transferred by Fiesta Tours to Puntarenas, the seaport village where you will board the vessel. The drive takes about 3 hours, including a stop on the way for a snack or lunch. The price of this meal is not included in your trip package. The ride will give you an opportunity to view some of the lush tropical forests and rich farmlands of the region.

Transfer from the vessel

At the end of your Cocos adventure, you will usually disembark the boat at 8 AM and be transferred back to your hotel in San Jose. The transfer takes approximately 2 hours, give or take.

Other transfers

If, for some reason, you should need travel to or from Puntarenas, other than the by the transport offered by the Undersea Hunter Group, a taxi service is, of course, available. The cost of independent transportation can run in excess of $100 one-way.

Land arrangements

While you are here in Costa Rica, it is certainly worth the extra time to experience some of the other aspects of our little country that truly make it a natural wonderland. Active volcanoes, white water rafting, zip-line tours, mountain biking, pristine jungles, coffee plantations, horseback riding, visits to craft centers and of course some of the most beautiful beaches in the world are among the activities and destinations available to you here. After all, you've come this far! We would be happy to arrange one-day tours or longer trips to more remote areas, at your request. Only Costa-Rican approved companies recommended by USHG will operate these tours.


Spanish is the official language, but English is widely spoken within regions associated with tourism.

Time Zone

Costa Rica and Cocos Island are 1 hour behind US Eastern Time during the North American winter and 2 hours during the North American summer.

Departure from Costa Rica

We strongly recommend staying one night after the return to land, in case of any unforeseen delays. You disembark the ship in Puntarenas at 8:00AM the morning of departure and you will be transferred to your hotel in San Jose.
