Two blocks east of Parque Guerrillero Heroico, you'll see a huge black-and-white ferry set up as a tatty memorial next to the river. This is El Pinero, the original boat used to transport passengers between La Isla and the main island. On May 15, 1955, Fidel and Raúl Castro, along with the other prisoners released from Moncada, returned to the main island on this vessel.
These days it's a meeting point for young reggaetón (Cuban hip-hop) fanatics (read: very loud music).
