Rocky Pacific islands, seasonal manta encounters and relaxed Guanacaste beach bases.
Use this travel brief to set arrival flow, local transit, and gear movement before you lock your itinerary.
The nearest practical international gateway for the Flamingo/Potrero circuit is Guanacaste Airport (LIR) near Liberia; travelers can reserve road transport from there to the beach base. San Jose's Juan Santamaria (SJO) is another gateway, but entails a longer overland transfer or an independently booked domestic connection. The Catalina Islands themselves are reached on local guided boats, not a scheduled public ferry. Tamarindo can be a pickup or accommodation location if your specific operator serves it. Airport; Operator pickup.

Playa Flamingo and Potrero are the simplest land bases for Catalina day boats. Tamarindo is a possible hotel or pickup point if the selected operator lists your location; Pacific Coast Dive Center publishes selected pickup zones and a quoted roundtrip supplement. An airport shuttle or rental car is practical for travelers with non-dive plans. Validate pickup hours and roads before committing to a tightly timed morning boat. Operator transfers; National travel guidance.
Costa Rica requires an eligible valid passport or travel document, a visa where the traveler's nationality requires one, proof of sufficient funds when requested, and evidence of return or onward travel. The maximum permission to stay is determined at entry; the Tourism Board currently notes up to 180 days for some groups, not an automatic entitlement for everyone. Check any yellow-fever documentation requirements based on recent travel origins before departure. Official entry guidance.
Pacific Coast Dive Center markets its main certified tour with standard dive gear and guides included; Rocket Frog Divers lists rental kit and computers separately. Freediving schools may supply specialized equipment for a course, while Catalina snorkel tours publish rental mask, fins and snorkel inclusion. Verify exact gear sizing, thermal protection, dive-computer requirements, nitrox certification, tank fills, safety buoy availability and wet-gear storage directly with the supplier. Scuba inclusions; Rental options; Freedive equipment.
Costa Rican colon (CRC)
CRC is the local currency; USD is widely accepted, and dive providers often quote USD. Cards are generally accepted for tourism services, but carry local cash for small transactions and double-check the conversion shown before paying. Official payment guidance.
The Tourism Board says ATMs are available in cities and tourist areas. Confirm your card works and access cash before an early boat departure; do not assume an ATM is beside a remote meeting point. ATM guidance.
120 V nominal (Tourism Board also describes 110 V outlets) • 60 Hz • A, B
North American-style plugs. Check appliance input labels and bring the correct adapter or voltage converter for your device. Power and plugs.
Communications
Mobile coverage and tourist-oriented Wi-Fi are common in developed coastal bases, but signal offshore is not dependable. Confirm the boat has marine communications independent of a passenger phone, and download booking receipts, offline maps and emergency contacts before boarding. Land-based connectivity should not be treated as an offshore safety system. General visitor infrastructure.
Language
Spanish is the national language. Some Guanacaste tourism and dive staff offer English-language briefings; verify language availability with the booked instructor or crew, especially for safety instruction, rather than assuming every course is bilingual.
Insurance
Carry medical travel coverage appropriate to Costa Rica and separate scuba or freedive accident and evacuation coverage if needed. Confirm that the policy covers your specific course, depth, repetitive dive, boat activity and recompression evacuation. Dive accident response and general health or trip cancellation benefits are not automatically the same. DAN services; Healthcare guidance.
Packing list
Pack certified dive documentation, any medical clearance needed, masks or corrective lenses, sun shirt, broad-brim hat, high-SPF protection, refillable water, wet/dry bags, a 3mm wetsuit with optional 5mm thermal backup if easily chilled, swim footwear as needed and an anti-seasickness plan. A light rain layer helps in green season. Bring a dive computer or arrange a rental rather than assuming it comes with every excursion. Thermal conditions; Equipment pricing.
