★★★★★★★★★★5.0 · 4,242 reviews · 8 to 10 hours (approx.) · from $129Our pick

This full-day Ocean Tours Mexico trip combines Tulum’s seaside Maya ruins, a short boat ride to a Caribbean reef, and a freshwater cenote cave. Guides such as Suly, Raul, Ulrich, and Mimi lead the day in English. Expect early pickup, a taco lunch, shared transport, and a $35 marine conservation fee paid in cash.

“I received a good understanding of the Mayan culture and history. The ruins could have been a day trip by itself. The cenotes where a good glimpse into the geology of the area. I was impressed with Aaron' s geologic knowledge. The snorkling was a test of endurance with the high waves but is one thing off my bucket list. The small group was great!”
