Fly primarily into Daniel Oduber Quiros International Airport (LIR) in Liberia for the northern Guanacaste coast. LIR to Coco, Ocotal or Hermosa is a road transfer, typically described by local operators as around 30-60 minutes depending on the exact hotel and road conditions. San Jose airport (SJO) is an alternative national gateway with a substantially longer ground journey. Book a known shuttle, taxi or rental vehicle. Dive boats leave from coastal bases, not from the airport. LIR official gateway; local road-transfer description.

The principal international arrival airport for Guanacaste and this coastal base. Reserve the final ground transfer in advance, particularly with dive bags. Official airports.

Costa Rica's larger central-valley international gateway; significantly less convenient for a short Papagayo diving stay than LIR. Tourism Board.

Playas del Coco has the clearest operator and service concentration. Use a prearranged airport shuttle, taxi or rental car to reach a specific base. Ocotal and Hermosa are separate beach areas, so check whether dive shop pickup, resort boat pickup, parking and after-dive return are included. Local buses are possible for some routes but not a dependable substitute for a dawn dive departure without independent timetable verification. Inland Rincon de la Vieja or Palo Verde outings need dedicated road transport and should not be represented as short beach transfers. Coco transport; hotel pickup examples.

Visa and permitted stay depend on passport nationality and the immigration officer, not the dive center. Costa Rica requires a valid passport/travel document, applicable visa where necessary, economic-means evidence if requested and proof of onward or return travel. The official government tourism guidance lists nationality groups with different maximum stays and notes yellow-fever certificate rules for travelers arriving from certain risk destinations. Verify current requirements before departure. A paid hotel or dive package is not immigration permission. Entry Requirements.

Coco operators advertise cylinders, weights, wetsuits, regulators, masks, fins and dive computers on published price or PADI listing pages, but exact rentals and sizes require confirmation. Rocket Frog prices its local two-tank outings separately from rental gear, and its three-tank packages require nitrox certification. Carry certification details, health/medical forms where requested, a suitable SMB, and enough thermal protection for severe cold-water pulses or thermoclines. Ask about the distance between your hotel and boat pickup and whether luggage is kept secure while diving. Bring apnea-specific gear only after confirming a dedicated instructor and site. Price and equipment terms; rental categories.

The colon is the legal local currency. U.S. dollars are widely accepted in tourism, including operator price lists, but a quoted USD fare does not justify an invented currency conversion. Cards commonly work for hotels, restaurants and established dive operators. Official travel-trade resources.

The Tourism Board says ATMs are common in cities and tourist areas. Carry a little local cash for small businesses, tips and uncertain transport arrangements; check cash/card and foreign transaction fees. Tourism Board.

U.S.-style Type A and B outlets are typical. Check device input rating and bring a suitable adapter if plugs differ. Electrical standard.

Communications

Spanish is the official language; dive and tourism operators often advertise English-speaking services. Ask your lodging and boat company about reliable mobile signal offshore, emergency radios and guest Wi-Fi rather than relying on a phone for an exposed Bat Islands trip. Purchase a Costa Rica-compatible SIM/eSIM if needed, but no carrier coverage guarantee was verified for offshore sites. Operator languages.

Language

Use basic Spanish for taxis, park offices and local businesses, with English common on established dive trips. PADI listings for local operators explicitly advertise English and Spanish; additional languages depend on staff and date. Operator language listing.

Insurance

Look for policy coverage explicitly including scuba depth, dive accident medical treatment, search and rescue and emergency evacuation where appropriate. Rich Coast states that insurance is mandatory for its remote Bat Islands dives and lists a separate day-policy price, but verify actual policy terms before relying on it. Freediving and snorkeling may need separate activity definitions. A travel-policy label alone is not proof of decompression coverage. Operator insurance requirement; DAN response.

Packing list

Pack sun protection, reusable water bottle, swimwear, dry bag, charged dive computer, certification documents and conservative thermal protection; local operators suggest 3mm to 5mm as a starting wetsuit range, while some upwelling-driven thermoclines may warrant warmer equipment. Add a light rain layer for the green season, closed-toe shoes for inland trails and motion-sickness supplies if appropriate. Carry locally accepted payment and confirm whether fins, SMB, flotation or apnea gear are rentals. Dive season guidance; .
