Perched on the southern edge of the Riviera Maya, Tulum is one of the Yucatan’s most iconic sites, a glorious Mayan citadel overlooking the white-powder beaches and turquoise waters of Mexico’s Caribbean. Constructed around the 13th century, Tulum was one of the last inhabited Maya cities and served as a seaport to the larger complex of Coba some 50km away. Today, tourism has firmly taken root making Tulum a good alternative to the larger resort strewn beaches of Playa del Carmen further north. Shaded by swaying palms, the gorgeous coastline is dotted with small, family-owned resorts that pride themselves on their relaxed, barefoot atmosphere. As ever, the crystal clear Caribbean waters lend themselves to excellent diving and snorkelling while for a change of scenery, you can explore the nearby Maya sites or head to the wonderful Sian Ka'an Biosphere Reserve and UNESCO World Heritage Site. Here you can take a nature safari through tropical forests, mangroves and marshes; tour the archaeological site of Muyil or enjoy a float trip along ancient Mayan channels.
