Bahía Windhond is a large, open bay on the southern coast of Isla Navarino within the remote Provincia de la Antártica Chilena, Chile. The bay is approximately 5 nautical miles wide from east to west and extends 6.5 nautical miles inland from its mouth, creating a significant expanse of sheltered yet exposed saltwater. The region has a rich history, having been inhabited by the Yagán people for millennia and later explored by European expeditions. The climate is maritime with consistent temperatures year-round, though the area is notorious for persistent inclement weather. The bay is characterized by a uniform, clean bottom and is flanked by low-lying coasts, making it highly susceptible to the prevailing westerly winds which can generate heavy, dangerous seas within the bay itself.
