Estrecho del Infiernillo

Estrecho del Infiernillo is a strait separating Tiburon Island from mainland Sonora. The waterway stretches considerable distances with varying widths that narrow significantly in certain sections.

Spanish explorer Francisco de Ulloa documented this waterway in 1539 during the early exploration of the Gulf of California. The strait subsequently became significant in the region's colonial and maritime history.

The Seri people, indigenous to this region, developed their own names for the waterway that reflect their deep connection to these waters. For them, this passage has always been central to their way of life and their relationship with the sea.

Navigation through the strait requires attention to tidal patterns and strong water currents that shift throughout the day. Visitors planning water activities should time their visits according to tidal conditions and prepare for variable water behavior.

The waters contain animal and plant species found nowhere else in the world, making them extraordinarily rare. This biological distinctiveness led to its designation as an internationally protected wetland site.
