Too Pretty Tulum
While there are many impressive Mayan ruins in the Yucatan Peninsula, Tulum's beachfront location - perched on a cliff overlooking the Caribbean Sea (and its fifty shades of blue) - is hard to beat. During my time there, I could not help but wonder how living in that walled city must have felt with such a million dollar view at your doorstep.
It is one of the best-preserved coastal Maya sites, and its construction date back to the years 1200-1450AD. Don't miss the buildings "The Castle" and "Temple of The Frescoes" and the "God of Winds Temple" (inset).
In addition to exploring the ruins, you can also swim at the beach at the bottom of the cliff.
To get here, drive about one hour south of south from Playa Del Carmen.
