The Gulf of San Miguel is the wide, mangrove-fringed bay outside La Palma, fed by the Tuira and Sabanas rivers. From the town waterfront you look out over a stretch of open water flanked by dense forest — on a clear morning the gulf has a cinematic stillness. Fishing boats work the shallows, and dolphins are regularly spotted.
The mangroves lining the river mouths are worth exploring by small boat if you have time before heading further upriver. Crocodiles, caimans, and a remarkable variety of wading birds inhabit the wetlands. Ask your guide or boatman to take you into the channels — it is a short detour from the main river routes and a good introduction to the ecosystem you will be travelling through.
