(Every day at 7:00 A.M) The clear showpiece of this Area, Xochicalco (whose name means the Place of the House of the Flowers) is the largest and most impressive complex in Central Mexico after Teotihuacan. Set as it is on a hill-top and with Teotihuacan-style geometric architecture, one is reminded of a more modest Monte Alban. One of Xochicalco's attractions is the Pyramid of the Feathered Serpent with some of the finest decorative panelling outside of the Yucatán; as well as the intriguing so-called Observatory cave. Includes:  lunch, transportation, bilingual tour guide. Price per person : $  130 .00 USD.
