Help! I am traveling to Bolivia for 9 days in April. I have 2 free days left on my agenda. Which is more interesting? 1. Driving in the Cordillera Real and Cordillera Quimsa Cruz areas for 2 days or 2. Driving to Copacabana and spending a night on Sun Island? My interests are cultural and nature. I like interacting with locals to learn about present day Bolivia. Relics and archeology, unless spectacular (like Machu Pichu) do not interest me. Which would be a better use of my time?
