"Havana’s cemetery is the 6th largest in the world. It’s an impressive place to walk or bike around. Most of Cuba (or at least Havana’s) most famous people are buried here and either a guide or cemetery worker can orient you to places of interet. The charge is $5 to get in, and you can walk for hours if you want. Not a lot of shade, so if it's summer, go early." - Noah Friedman-Rudovsky
