Tulum Ruins.

Tulum is defined by its dramatic cliffside geography, a rare departure from the inland jungle settings of most Maya archaeological sites. Once a powerful 13th-century maritime hub, the compact, walled city sits on limestone bluffs overlooking the turquoise Caribbean. The most iconic structure, El Castillo, served as both a landmark for trade ships and a ceremonial center. Nearby, the Temple of the Wind God occupies a rocky outcrop; its circular base was designed to honor the deity of the air, and its architecture reportedly whistled to warn residents of incoming hurricanes. Unlike the sprawling ruins of Chichén Itzá, Tulum is easily walkable and centers on the relationship between stone and sea. Visitors often descend the steep wooden stairs to swim at the small beach tucked directly beneath the ruins, where iguanas sun themselves among the weathered gray facades. While the vibrant red and blue paints of the 1500s have faded, the site remains one of the most visually striking remnants of the late Postclassic period.
