What it is
Marks the arrival of the world's largest gathering of whale sharks off the island. Conservation talks and children's workshops on shore, with regulated swim trips leaving at dawn from Puerto Juárez and the island pier.
Dates can shift by a day or two when a local council moves the programme to a weekend, so confirm with the town hall before booking non-refundable travel. Accommodation in Isla Mujeres tends to sell out weeks ahead of the festival and prices rise sharply on the main night.
