San Andrés & Providencia

San Andrés sits closer to Nicaragua than to the Colombian mainland, a geographic quirk that's shaped everything about it — a distinct Creole culture, English-inflected local dialect, and water in a genuinely improbable range of blues most visitors assume is edited before they see it in person.

Getting there and the tourist card

Avianca, LATAM, and Wingo run daily flights from Bogotá (about 2 hours) and less frequent routes from Medellín and Cartagena. Every visitor, regardless of nationality, must buy a mandatory tourist card before boarding — it costs COP 153,000 (roughly $38) in 2026, purchased at the airline counter or online in advance, and funds the archipelago's tourism infrastructure. It's separate from any Colombia visa question and applies even to Colombian citizens from the mainland.

What to do on San Andrés

1. Johnny Cay — a tiny, palm-covered islet a short boat ride from town (boat tours run $12–20), one of the most-photographed spots in the archipelago.
2. Cayo Cangrejo — a quieter snorkeling spot with healthier coral and far fewer crowds than Johnny Cay.
3. Spratt Bight — the main town beach, easy to reach on foot, good for an easy swim or sunset stroll.
4. A full-island tour ('vuelta a la isla') — a half-day loop by golf cart or taxi covering the island's viewpoints and smaller beaches.

Diving in San Andrés

San Andrés has around 40 dive sites and roughly 20 dive shops, making it one of Colombia's most developed diving bases — walls, wrecks (including the Blue Diamond, a wreck about 15 meters deep, accessible from shore or boat), and healthy reef life suited to divers of every level, including complete beginners. Visibility peaks in the drier windows, roughly December–March and July–August.

Providencia — the quieter island

A 25-minute flight from San Andrés, Providencia is smaller, less developed, and — by the near-universal opinion of people who've done both — the more beautiful of the two. Southwest Bay's beach is a genuine highlight, and McBean Lagoon National Natural Park protects some of the archipelago's healthiest reef. It's the pick for travelers who want a slower, more remote Caribbean island experience without San Andrés' bigger crowds and cruise-ship traffic.

San Andrés or Providencia — or both?

With 3–4 days, San Andrés alone covers the essentials well. With 5+ days, adding Providencia is worth the extra flight and cost — it's a genuinely different pace and feel, not just more of the same beach. Many divers specifically build a trip around Providencia's less-crowded sites.

What it costs

Best time to visit

December–March and July–August are the driest, calmest windows with the best diving visibility — also the busiest and priciest months given domestic Colombian holiday travel. May–June and September–October trade a slightly higher chance of rain for noticeably lower prices and thinner crowds.

Mistakes worth avoiding

• Forgetting the tourist card — airlines will not let you board without it, and buying it in a rush at the counter costs the same but eats valuable time before your flight.
• Only budgeting for San Andrés and being surprised by Providencia's extra flight cost if you decide to add it once there.
• Skipping travel or dive insurance — genuinely worth having given the islands' remoteness from mainland medical facilities.
