Samaipata is a charming mountain town located about 2 hours southwest of Santa Cruz. The main attraction here is the Inca ruins known as El Fuerte. The ruins are a huge mysterious complex, much of it unexcavated. From what remains, it's hard to envision the site's former glory. The most impressive structure is the Chinkana, also known as the Labyrinth. It consists mainly of a hole that was originally 30m (9 ft.) deep. From the top of El Fuerte, you have great views of the surrounding mountains and perfect sightlines of other Inca sites. Most scientists believe that the Incas built these villages in a pattern. At this site, you will also see what are believed to be amphitheaters and temples for religious ceremonies.
