3–4 hours
Light activity: mostly sitting and short, flat walks for boat boarding and estuary piers; suitable for most fitness levels.
Cruise the sheltered bays of Huatulco with local guides who know where winter migrants and resident shorebirds concentrate. This 3–4 hour tour mixes boat-based viewing, scopes and field guides, and an intimate look at mangrove estuaries and coastal birdlife.
The morning arrives humid and sharp, the Gulf of Tehuantepec breathing salt and heat onto the boat's bow. Binoculars fog briefly against the sea air, then clear to reveal a black flash of frigatebird hawking thermals above a row of barges, and farther, a white line of pelicans gliding low and steady. Guides call out brief notes—local names, flight styles, the telltale white wing patch of a migratory sandpiper—and the list on the clipboard grows.

Morning departures give calmer water and better side-lighting for identifying plumage details and photographing birds.
Salt spray and humidity fog optics—keep a cloth handy to clear scopes and camera lenses between stops.
The sun is intense over open water; choose non-chemical sunscreens to protect coral and marine life.
Tours provide local fruit and drinks, but bring extra water if you’re sensitive to heat or prone to seasickness.
The bays of Huatulco have long supported small fishing communities; the national park was later established to protect coastal habitats while guiding sustainable tourism.
Huatulco National Park protects mangroves and coral habitats; visitors are asked to minimize disturbance by staying on designated routes and using reef-safe products.
Personal optics are quicker to hand than shared binoculars and help you follow active flocks.
Protects from sun over open water and reduces glare when scanning for birds.
