Old Town Square (Plaza Vieja) in La Habana Vieja, Cuba, is highly accessible on foot, though cobblestone streets can be uneven. It's excellent for both solo exploration, offering ample opportunities for people-watching and photography, and for guided visits which provide rich historical context. Open year-round with no seasonal restrictions, though the cooler, drier months (November-April) are more comfortable for visiting Havana. Entry to the square itself is free, with costs arising from cafes, restaurants, and surrounding attractions; expect to spend $10-$30 USD for a meal or drinks. A typical visit duration can range from 30 minutes for a casual stroll to 2-3 hours if enjoying a meal or visiting a site like the Camera Obscura. This lively square is a hub of architectural beauty and local life, featuring diverse buildings, eateries, and often street performances, making it a quintessential Havana experience.
