A dolphin and whale conservation outfit that funds itself by running tours, meeting guests at the entrance to the dock in Marina Chahué — they have no office, which they are cheerful about.
Trips combine snorkelling with wildlife watching: dolphins year-round, turtles and mantas, and from December to March humpback whales, which come south to Oaxaca to calve. They work to approach distances rather than chasing, which is the difference between a wildlife trip and a boat ride.
They prefer WhatsApp to email because they are usually at sea, but the number sits behind a short link rather than being published, so only the address is listed here.
