🇨🇴Colombia

There is no one-month answer for both Colombian seas. December-April is a useful starting point for mainland Caribbean trips to Cartagena/Rosario and Santa Marta, but dry-season trade winds and Tayrona upwelling can change boat and water comfort. February-April often suits San Andres and Providencia when the islands are less rainy. Malpelo operators frequently discuss January-April for schooling hammerheads, while July-October is attractive for Gorgona humpback observation. Caribbean tropical-cyclone season runs June-November. Always check the specific operator's departure, park closures and daily sea state rather than treating a seasonal label as a guarantee.

The easiest documented training centers are Taganga near Santa Marta, Cartagena/Rosario and San Andres, with supervised introductions and Open Water courses at selected local shops. Providencia also has beginner instruction, although flights and smaller service capacity make it a more deliberate island trip. A beginner should book an accredited instructor, ask which protected-area reef is actually permitted and use a depth appropriate to the course. Tayrona's annual closures can cancel marine activity even when a Taganga dive shop is operating. Malpelo is not for beginners: the park requires advanced certification and a minimum of 35 logged dives.

Malpelo's national park requires Advanced-level scuba certification and at least 35 logged dives. Its rules also call for specified personal safety equipment, including an AIS/Nautilus-type locator, light, knife and surface marker, with guided daytime diving from an authorized expedition vessel. Individual liveaboard companies may require more, such as 50 total dives and demonstrated ocean-current experience. The long Buenaventura crossing, powerful currents, thermoclines and remote medical access make this a serious expedition rather than a normal holiday reef dive. Ask for written confirmation of boat authorization, Nitrox requirements, insurance and equipment before paying.

Parques Nacionales identifies July-October as the principal seasonal humpback observation period around Gorgona, with wildlife activity varying by year and sea conditions. An authorized day visit can combine coastal interpretation, rainforest trails and a chance of seeing whales, while separate approved dive vessels may offer multi-day programs at sea. Do not expect to swim with, touch or pursue whales: ethical viewing uses regulated distances and a responsible skipper. Park trail or boat access can be suspended in heavy rain or swell. Reserve through an approved operator and check the latest park notice before flying to Guapi.

Not in ordinary visitor accommodation under the park's current arrangements. Parques Nacionales states that tourist lodging and food service on Gorgona island remain suspended, with land visits operating as approved day excursions. That does not prevent separately authorized multi-day diving expeditions from sleeping aboard their vessels, but such trips are not stays in island hotels. Many non-divers would be better served by a Guapi-based tour with one park day, assuming the operator has suitable access and a secure transfer plan. Confirm current park capacity, insurance, guides, boats and services rather than relying on older hotel listings.

San Andres is the more flexible base for a short mixed-group holiday: it has a larger airport and services, reef and wreck outings, shallow snorkeling and documented AIDA freedive instruction. Providencia feels smaller and slower, with locally guided reef or wall boats, guesthouses, Raizal culture and Santa Catalina walks. To reach Providencia, book a separate San Andres-Providencia flight, currently advertised by SATENA, and allow schedule buffers. Both islands generally require the archipelago tourist card. In late 2026, do not include Crab Cay or its surrounding waters until the announced temporary closure is formally lifted.

Tayrona's published recurring park tourism closures are February 1-15, June 1-15 and October 19-November 2; the last scheduled 2026 closure ended November 2, with the park announcing tourism would resume November 3. Other weather, security or management restrictions can still occur. Separately, Crab Cay and its surrounding marine area in Old Providence McBean Lagoon are closed under a September 2026 notice, with a planned December 17 reopening subject to works and official confirmation. Access to other approved Providencia sectors is governed separately. Never infer that an advertised snorkeling tour overrides a park closure.

The tourist card generally applies to nonresident visitors entering San Andres, Providencia or Santa Catalina. Confirm current pricing, exemptions and payment channels with your airline or the archipelago government before departure. It is separate from Colombian immigration permissions, park tickets, boat fares, visitor accident insurance and scuba packages.

Charges differ by protected area, nationality, residency and sometimes the vessel's flag. Tayrona posts foreign nonresident admission rates by season and a separate Bahia Concha tariff. The Gorgona park page lists a foreign nonresident admission charge, while Malpelo charges relevant diver-day and vessel fees on authorized liveaboards. Rosario's publicly displayed San Bernardo tariff is not a verified Rosario-sector rate. The Old Providence park tariff does not authorize entry into temporarily closed Crab Cay. Always request an itemized operator quote and distinguish entry, park-approved accident assistance, regular dive insurance, transport, guide and gear costs.

They are separate Pacific journeys. For Gorgona, the park describes travel through Guapi, often via a Cali connection, then a roughly 1.5-hour licensed speedboat to the protected island; specific packages and return conditions vary. Malpelo visitors normally arrive through Cali, join a vetted operator transfer to Buenaventura and board an authorized expedition liveaboard for an offshore crossing of around 36 hours each way. There is no public Malpelo ferry, island accommodation or casual independent dive landing. Government advisories warn about security in parts of Cauca and Valle del Cauca, so book supported transfers and avoid improvised road travel.

San Andres is a strong first option because La Piscinita, Acuario-area tours and beach time can fit around diver outings. Providencia adds quieter guided coral habitats and local culture, provided you avoid the current Crab Cay closure. A Cartagena stay offers licensed Rosario Islands snorkeling alongside historic-city attractions, while Santa Marta has selected Tayrona sectors when the park and surf allow. Gorgona can offer approved surface nature viewing but requires more complex Pacific access. Malpelo is not an independent snorkel excursion. Check site-specific current, safe entries, lifejacket availability and no-feeding rules before entering.

San Andres has a documented dedicated freedive school advertising AIDA 1-4 programs, coached depth sessions and higher-level instruction. It is the most defensible first choice for someone who wants structured apnea training during a Colombian trip. Separate providers or occasional camps may offer courses around Providencia or Santa Marta, but confirm dates and actual instructor staffing rather than treating the location as a permanent program. Choose safety cover, rescue training and an appropriate open-water line over a depth claim. Avoid solo breath-hold training and never assume general scuba or snorkeling charters provide qualified freedive supervision.

Confirm the vessel has emergency oxygen, working radios or satellite communications, a documented evacuation plan and appropriately trained crew. Check your diving insurance for recompression therapy, rescue, air evacuation, activity depth limits and excluded regions; mandatory park visitor accident cover is not the same product. On Malpelo and Gorgona, severe weather and offshore distance can delay care, and no on-site hyperbaric chamber should be assumed. For an immediate emergency call Colombia's 123, or 146 for maritime emergencies, then contact DAN at +1-919-684-9111 for dive-medicine support. Review current security advisories before inland Pacific transfers.

Cartagena provides museums, a historic walled center, restaurants and locally arranged Rosario community outings. Santa Marta offers city history and, when the park is open, designated Tayrona coastal walks and viewpoints. San Andres has beach days, mangroves and town amenities; Providencia has local food, guesthouses and Santa Catalina heritage paths. Gorgona is possible as a guided rainforest and former-prison day visit, but current visitor accommodation on the island is unavailable. Malpelo is a specialist open-sea dive expedition without visitor landings or a normal non-diver activity program, so it is usually a poor mixed-group choice.

Entry requirements depend on nationality and itinerary. U.S. visitors generally do not need a visa for tourism of up to 90 days, but must satisfy immigration and airline document checks; other passports need their own verification. Migracion Colombia currently describes its free Check-Mig online preregistration as optional, available from 72 hours to 1 hour before arrival or departure, even though older travel instructions may differ. The Colombian Ministry of Health recommends yellow-fever vaccination for travel to designated risk areas and some high-risk park visits may require proof. Check your exact municipalities and any origin-country vaccination conditions before flying.
