Isla Bastimentos National Marine Park & the Zapatilla Cays

1.What the park actually protects

More than 80 species of coral grow inside the park boundaries, and four species of sea turtle — hawksbill, green, loggerhead and leatherback — haul out to nest on its beaches. Playa Larga, on the wild east side of Bastimentos, is the main nesting stretch, active roughly April through October.

If you're here in season, go with a guide and follow the rules: no lights, no touching, no flash.

2.How do you get to the Zapatilla Cays?

You can only reach the Zapatilla Cays by boat — there's no ferry and no walk-up entrance to the park. They come as part of the classic full-day boat loop from Bocas Town: Dolphin Bay first, then Crawl Cay for lunch and a snorkel, then a couple of hours on the cays before the run home. The whole trip takes about six hours.

If you just want to poke around Bastimentos island itself, a water taxi from Bocas Town to Old Bank takes 10 minutes and costs $3–5 — but that's outside the park proper.

3.How much does a Zapatilla Cays tour cost?

Expect to pay about $25–45 per person for a shared Zapatilla Cays tour booked on the island — we've seen $40 quoted with mask and snorkel included — plus the park entrance fee of $10–20, which as of 2025 must be paid online in advance through the Panamanian government site. Kids under 12 are free.

On that entrance fee, sources disagree — some say $10 for foreigners, the official 2025 listing shows $20 for non-resident adults — so budget for the higher number and ask your tour operator to confirm before you pay.

The upgrade worth considering: a private water taxi for the day, around $120 for two people plus fees. You skip the circuit and get the maximum stretch of beach time, which on a good day is exactly what you want.

4.What it's actually like

The cays deliver: firm white sand, water you can see your feet in, and an absurd number of seashells. One island has a short nature trail through the interior if you want shade. The snorkelling right off the cays is the best of the standard tour — angelfish, parrotfish, groupers, the occasional lobster or moray tucked into the coral.

The honest caveat is the rest of the loop. The Crawl Cay snorkel stop is mediocre — soft coral, small fish, fine for a first-timer, forgettable if you've snorkelled elsewhere. And the Dolphin Bay stop comes with the boat-crowding problem we've written about separately; ask your captain to keep his distance.

5.When to go and what to bring

The best months to visit the Zapatilla Cays are September to November, when the water is at its calmest and clearest — our pick if snorkelling is the point. January through April is the drier window. The crossing is exposed either way, so on a rough day expect a wet ride, and be mentally prepared for a captain to reroute or cut a stop.

It rains in Bocas in every month — a burst of rain mid-tour is normal, not bad luck. Bring everything: water, snacks, sunscreen, cash in small bills. The islands have no shops, no restaurants, and no shade beyond the treeline. Pay the park fee online before the morning of — island Wi-Fi at 7am is not where you want to be doing government paperwork. Sandflies show up at dusk, so plan to be back on the boat by late afternoon anyway.
