Isla de Janitzio is the main island of Lake Pátzcuaro in the state of Michoacán, Mexico.The town of Janitzio, which means "where it rains", is located atop the hill. Janitzio can only be reached by boats which run regularly back and forth from about 7:30 am to 6 pm, accessible from Pátzcuaro's pier. It is the largest of five islands in Lake Pátczuaro. These boats can be hired to take visitors around other parts of the lake. The boats are pretty regular and takes approximately 25 minutes to reach the island. The town is known for the butterfly fishermen who are skilled at lowering their butterfly-shaped nets to catch the local cuisine "pescado blanco". These fisherman were at one time depicted on the reverse of the 50 peso banknote.
The island is the subject of Silvestre Revueltas's 1933 composition Janitzio.
