This hamlet is in Magallanes y la Antartica Chilena, Chile, and has a very small river flowing entirely on the beach, slightly to the south of the city center.

The remaining 100 Yagan people today are concentrated around Caleta Wulaia and Bahia de Mejillones, where they first settled on Navarino Island.

At the muddy and sandy beaches and river deltas of its coast, the lowest elevations occur, reaching less than 2 feet (61 cm).

The cove is extremely shallow, with its maximum depth being 1.5 feet (46 cm) and minimum seabed elevation being sea level.

[1] There is a Robert FitzRoy cairn approximately 150 meters to the south-southeast of Caleta Wulaia hamlet center, on top of a 4-meter-high rise at the point where a small peninsula joins the mainland.

Temperatures are very ocean-moderated, and snow is common in winter, spring and fall due to the southerly location combined with the oceanic proximity.
