While ruins, including the El Castillo and Kukulcan pyramids, are the primary reason for visiting Chichen Itza, there is a wealth of other attractions as well. Otherworldly bird-watching and stargazing experiences can be found within the Maya Jungle Reserve and in Hacienda Chichen's Bird Refuge. Yaxkin Spa makes the most of this sacred space with holistic Mayan healing. Freshwater sinkholes offer unforgettable swimming. Drive or catch a bus from Merida or Cancun. Day trips run from both cities.
