Day 1: Cenote Snorkel Circuit near Tulum
Gran Cenote & Cenote Calavera
Start at Gran Cenote (MX$500 entry), 4km from Tulum centre — the most famous cenote on the Riviera Maya and the most beautiful for good reason. Crystal-clear turquoise water fills a limestone cavern with underwater stalactites, tree roots reaching down from above, and small freshwater turtles gliding through shafts of sunlight. Snorkel gear is available to rent (MX$80) or bring your own. Then drive 5 minutes to Cenote Calavera (MX$300) — an open-air sinkhole with three holes in the limestone roof, one of which is used for jumping 5 metres into the water below.
Cenote Zacil-Ha & Jungle Swimming
Head to Cenote Zacil-Ha (MX$200), a locals' favourite 10 minutes from Tulum with a huge open swimming area, a zipline over the water (included in entry), and platforms for jumping. The vibe here is more swimming hole than sacred grotto — families, music, and hammocks scattered between the trees. The water is deep, clean, and refreshing after the morning's exploration. Food stalls at the entrance sell tacos and agua fresca. Spend the afternoon floating, jumping from the platforms, and cooling off.
Tulum Town Tacos
Return to Tulum town (pueblo, not the hotel zone) for dinner. The taco stands on the main avenue serve al pastor, cochinita pibil, and poc chuc tacos for MX$20–30 each — some of the best street food in Mexico. Wash it down with a michelada (MX$50) or a fresh horchata (MX$25). The town is walkable and lively in the evening with mezcal bars, craft shops, and a backpacker-friendly atmosphere that feels less corporate than the beach zone.
