Around 20km south of Puntarenas is Mata de Limón, a picturesque little hamlet situated on a mangrove lagoon, locally famous for its birdwatching. If you arrive during low tide, you'll see flocks of feathered creatures descending on the lagoon to scrounge for tasty morsels. Mata de Limón is divided by a river, with the lagoon and most facilities on the south side.
