Calle Martí, the main street, leads southeast to the city cemetery; from there, turn east onto Avenida Rosario for two blocks, where steps ascend to Colina Lenin (Lenin Hill, Calle Vieja, e/ Enlase y Rosaria). A three-meter-tall bronze face of the Communist leader is carved into the cliff face. A dozen life-size figures (in cement) cheer him from below.
A pitiful museum (tel. 07/797-6899, Tues.–Sat. 9 a.m.–5 p.m., free) atop the hill is dedicated to Lenin and various martyrs of the Cuban revolution.
The Colina is more directly reached from Parque Guaycanamar (Calle Martí, six blocks east of the harborfront) via Calle Albuquerque and 24 de Febrero; you’ll reach a metal staircase that leads to the park. Bus #29 will take you there from the Regla [1] dock.
