A long-time retreat located on the Caribbean coastline of Mexico’s Yucatán Peninsula, Tulum has emerged as a playground for spirituality and community – for good reason. An eight-mile strip of sand situated between a tropical jungle, Mayan ruins, and the Sian Ka’an biosphere, Tulum presents a heady hideaway that has magnetized the free-spirited crowd, no doubt in part to its celebration of eco-friendly practices and organic cuisine, and a realm of sophisticated hotels. Open to those seeking spirituality, sun, and nature alike, the beach settlement heralds a new template, as chronicled in Assouline's latest book, which explores the locale's unique translation of the modern lifestyle of travelers.
