My family visited four great UNESCO World Heritage Sites in 1999 - 1. Machu Picchu, 2. Inca Trail, 3. Cuzco, during the Festival of Inti-Raymi, and 4. Manu National Park which is the world’s largest and most biodiverse rainforest reserve in the world, with over 1,000 bird species. This is my favorite site in over 60 UNESCO sites I have been to.
