You step onto a swift sports boat at Pegasus dock as the city recedes — Cartagena’s colonial walls blink back at you while the Caribbean opens ahead, a shelf of turquoise and deeper blue that dares you to explore. The boat cuts a bright line through the channel; forts at Bocachica lean over the water like old sentries, then islands and mangroves slide into view.

Bring reef-safe sunscreen
Coral reefs in the Rosario and Barú area are sensitive; use reef-safe SPF to protect marine life and your skin.
Wear water shoes
Beaches and reef flats can be sharp or silty; water shoes make beach entries, rocky landings and boat ladders easier.
Protect valuables in a dry bag
Long boat rides and beach time mean phones and wallets can get wet — a medium dry bag keeps essentials safe.
Choose night timing carefully for plankton
Bioluminescence is clearer on moonless nights and away from shore lights; alert your guide if you prefer darker conditions.
Reef-safe sunscreen
Protects skin while minimizing harm to corals and reef organisms.
Water shoes
Protects feet on rocky shores, boat ladders and coral flats.
Dry bag (10–20L)
Keeps electronics, documents and spare clothes dry during boat transfers.
Light long-sleeve rash guard
