La Ventana is a coastal village on the Sea of Cortez in Baja California Sur, Mexico, within a region known for high marine biodiversity. It is recognized for freediving opportunities linked to seasonal aggregations of Mobula rays that migrate through the Sea of Cortez, forming dense surface groups during feeding and reproductive periods in late spring and early summer. The surrounding waters are also inhabited by marine mammals such as sea lions and dolphins, along with several cetacean species including blue, Bryde’s, sperm, humpback, pilot, and false killer whales. Underwater encounters typically occur in open water rather than along reef systems. Other nearby activities include wind- and water-based sports along the bay. Local operators and guides can be contacted to organize freediving and wildlife observation excursions.

• Visibility: Commonly 15–25 m during late spring and summer, decreasing to around 10–20 m in cooler or windier periods

• Depth Range: Most Mobula ray encounters occur from the surface to approximately 10–20 m, with deeper open-water areas offshore

• Water Temperature: Approximately 20–30 °C depending on season

• Water Conditions: Variable; calmer seas are more common in summer, while winter and transitional seasons can bring stronger winds and surface chop

• Seasonality: Mobula ray aggregations typically occur from April to July; general freediving conditions are best from spring through early autumn

• Transportation: by road from La Paz or after flying into regional airports such as La Paz International Airport (LAP) or San José del Cabo International Airport (SJD), followed by a car transfer of approximately 1.5 to 3 hours depending on the route and starting location

• Local rules: Marine wildlife interaction guidelines apply, including maintaining appropriate distances and following local operator and protected-area regulations
