Hidden gems of Yucatan, such as Tulum, Akumal, Chetumal, Chichen Itza and Merida, offer an authentic taste of Mexico. Akumal and more Caribbean-style Chetumal, near the Belize border, deliver delectable white-sand beaches and great snorkelling. Merida, Chichen Itza and Tulum, with their ancient ruins, offer a passage into the Yucatanâs native history. Nature lovers can jungle trek and swim in subterranean sinkholes filled with crystal-clear water. Bike around the ruins and hop between towns in colectivo vans.
