Estero de Punta Banda birding walk

The walk begins at the estuary access point reached by driving south from Ensenada toward Punta Banda and parking near the sandspit, with free access and no facilities beyond informal parking. The out-and-back route covers about 5 km along the sandspit that encloses the Punta Banda estuary, entirely flat and following firm to loose sand depending on the tide, with essentially no shelter or shade along the entire length. Landmarks along the way include the estuary mouth near the parking area, mudflats exposed at low tide that draw the largest concentrations of shorebirds, and the outer beach facing the open Pacific on the far side of the spit; most visitors turn around once the open beach is reached, though the spit continues further for those with time. This is one of the most important shorebird wintering sites on the Pacific flyway, and brant geese, herons, egrets and thousands of migratory waders can be seen feeding on the mudflats, particularly at low tide and in the early morning. There are no water sources on the spit, so hikers should carry their own, and there are no huts or shelters of any kind. Wind off the ocean is near-constant and can be strong in the afternoon, so a wind layer is worth carrying even on an otherwise warm day, and birders should check tide tables in advance, since the mudflats are only exposed within a few hours of low tide.
