The Yucatan Peninsula is full of Mayan ruins. We aren't huge history buffs, but still wanted to check out a few of the sites. During our time in Tulum we visited the two most convenient locations - Tulum and Coba.
The Tulum site is right on the beach - prime real estate!!! A quick bike ride from the town or hotel/beach zone.
The Coba ruins are 25 miles inland (easy drive) and located in the jungle. This site is barely even excavated.
