Though not as large as some of the more famous ruins, Cobá is ‘cool’ because you feel like you’re in an Indiana Jones flick. It’s set deep in the jungle and many of the ruins are yet to be excavated. Walk along ancient sacbes (stone-paved avenues), climb up vine-covered mounds, and ascend to the top of Nohoch Mul for a spectacular view of the surrounding jungle.
From a sustainable-tourism perspective, it’s great to stay the night in small communities such as Cobá, but truthfully it has pretty slim pickings in the way of hotel offerings. Other ways to help are by hiring local guides, buying local crafts and simply stopping here for lunch.
