Mexico's Yucatán peninsula is way more than just the Mayan Riviera — and, dang it, this epic six-day adventure is going to prove it. Staying in the world’s best hostels as you go (we’re biased, but whatever), get ready for a tour that’s seriously non-stop fun and sun. Hit up a number of different cenotes and cool off in the crystal-clear waters of these natural jungle sinkholes. Wander the ruins of Chichen Itzá before having the most amazing meal ever: a delicious Yucatecan dinner inside a cenote! Then, wrap up your tour in Tulum with white sand, turquoise waters, and beach bars galore.
