One of the planet's most spectacular marine gatherings: up to tens of thousands of Munk's devil rays (Mobula munkiana) swirl in 'fevers' between La Ventana, Cerralvo Island (also called Jacques Cousteau Island) and Cabo San Lucas. Peak action late April to June when nutrient upwellings bring plankton blooms and rays launch 2 m out of the water in synchronized belly flops. Snorkel and freedive only.
