Cueva de los Portales
Lonely Planet review
During the October 1962 Cuban Missile Crisis, Ernesto 'Che' Guevara transferred the headquarters of the Western Army to this rather spectacular cave, 11km west of Parque la Güira and 16km north of Entronque de Herradura on the Carretera Central. The cave is set in a beautiful remote area among steep-sided vine-covered mogotes and was declared a national monument in the 1980s.
A small outdoor museum contains a few of Che's roughshod artifacts including his bed and the table where he played chess (while the rest of the world stood at the brink of nuclear Armageddon). Three other caves called El Espejo, El Salvador and Cueva Oscura are up on the hillside. Again, this area is brilliant bird-watching turf: trips can be arranged at the Hotel Mirador, or you can ask the staff at the cave entrance. There's a campismo and small restaurant outside the cave. Both have been closed since Hurricanes Gustav and Ike.
