Discover the Mayan ruins and the Caribbean Sea before anyone
Pick up at the meeting points in Cancun or Riviera Maya (indicated below in the "Important information" section) between 5:00 a.m. and 6:00 a.m.
At the same meeting points Cancun and Riviera Maya between 6:00 p.m. and 7:00 p.m.
This is such tough question! We must say -both are a must on your visit to Mexico-. Both are world-famous Mayan ruins, but the kind of tourist attraction and the type of activities you can do there are quite different. In Tulum, you can visit the ruins and spend free time on the beach. In addition, you will be at your accommodation by 3 p.m. and can use the rest of the day for another activity. Chichen Itza, is also very famous, is worth a visit and you can combine it with a visit to a cenote.
Our recommendation is: make time to do both activities because they're really worth it.
