Do I need a 4x4 vehicle?

No. Most roads to ruins and popular cenotes are paved. A standard sedan is sufficient.

Is it safe to drive in the Yucatan?

Yes, but avoid driving at night due to unlit roads, stray animals, and topes (speed bumps) that are often unmarked.

Planning a 7-Day Yucatan Cenotes and Ruins Trip

Base yourself in Valladolid for three nights to cover the central ruins and cenotes, then move to Tulum for four nights to hit the coastal sites and beach clubs. Rent a car at Cancun Airport to maintain the flexibility needed to reach remote cenotes before tour buses arrive.

Rent a car upon arrival. Do not rely on ADO buses or collectivos if you want to see three cenotes in one day. Rent a car at CUN. Ensure your rental includes full 'CDW' (Collision Damage Waiver) insurance, which is mandatory in Mexico.
Prioritize early starts. Ruins like Chichén Itzá and Coba get unbearably hot and crowded by 11:00 AM. Arrive at the gates by 8:00 AM. For cenotes, arriving at 9:00 AM ensures you get an hour of swimming without a crowd.
Use cash for entry fees. Most cenotes are family-run and do not accept cards. Carry 3,000 MXN in small denominations (100 and 200 peso bills) for daily entry fees, which usually range from 150 to 300 MXN per person.
Book one guided tour only. Hire an official licensed guide at the entrance of Chichén Itzá for 800 MXN. You don't need a guide for cenotes, but you do need one for the context of the Maya history at the major ruins.
