El Fuerte de Samaipata is a very beautiful and interesting Pre-Columbian archaeological site located in Santa Cruz Department in Bolivia (UNESCO World Heritage Site). The archaeological site is unique as it contains buildings of three different cultures: Chanè, Inca, and Spanish.
Perfect for hiking. I love it. And when you are there you should try out the echo... just scream and listen. ;)
The ceremonial sector covered with carvings of both Inca and pre-Inca origin
It is a paradise of beautiful butterflies
