Here are some interesting archeological sites in the Yucatán Peninsula. They are less-visited sites and for some of them, the highlight is the road to get there, and the feeling of being in a remote area far away from any big centres.
From 250 to 695 AD, Calakmul was the leading city of the region. It was the great rival of Tikal in Guatemala.
This site was only rediscovered in 1990. Its main attractions are the frescoes and stucco friezes.
