The main things to see in the park are south of the lake, including the Galería de Arte Amelia Peláez . Up the hill there's a dramatic white marble monument to Lenin (1984) by the Soviet sculptor LE Kerbel, and west along the lake is an overgrown amphitheater and a lackluster aquarium with freshwater fish and crocodiles. The 1985 bronze monument to Celia Sánchez , who was instrumental in having Parque Lenin built, is rather hidden beyond the aquarium.
Most of these attractions are open 9am to 5pm Tuesday to Sunday, and admission to the park itself is free. You can sometimes rent a rowboat on the Embalse Paso Sequito from a dock behind the Rodeo Nacional , an arena where some of Cuba's best rodeos take place (the annual Cattlemen's fair is also held here). A 9km narrow-gauge railway with four stops operates inside the park from 10am to 3pm Wednesday to Sunday.
