Wildlife
History
Barú was historically a fishing and salt-harvesting area that fed Cartagena; the island’s reefs formed from coral growth atop limestone shelves.
Conservation
Tourism concentrates pressure on fragile coral and plankton; use reef-safe products, avoid littering, and follow guides’ low-light rules to minimize impact.

Protect reef life
Use reef-safe sunscreen and avoid soaps or lotions before entering the water to protect coral and plankton.
Night viewing etiquette
Turn off flashes and bright lights during the plankton cruise — low light improves visibility and minimizes disturbance.

Take motion-sickness medicine before departure if you’re prone to nausea; the trip includes boat transfers that can be choppy.
Bring small cash
Carry small Colombian pesos for extras like snacks, tips, or Balinese bed upgrades at the beach club.
