The tour was very interesting with a knowledgeable guide. Tulum was the only Mayan city on the sea. Our guide explained that this was 1 of the last cities to be constructed by the Maya, only city on the coast. The walled city was the home of the elites, the nobles and priests. The common people lived outside the walls. When discovered the city was overgrown with jungle. When removed, the buildings collapsed as the soil and roots were holding the structures upright. A few residences, important palaces and temples were reconstructed, the remainder of the site is trees and lawn. Nothing has been excavated outside the walls. There is beach access, which seemed popular as many were in the water. There are no changing facilities, bathrooms, or lifeguards, swim at your own risk. The guide well informative talked to much for me. Viator contracts with Passions Tours who hire drivers to pick up tour members at their resorts. We boarded the minivan on the side of the highway. Passions tours subcontracts with drivers and tour guides. When we arrived at the site we were dropped off at the parking lot entrance in order to avoid parking fees. A tram was included in the price to transport us to the park entrance and then back to the parking area. A cold bottle of water was provided 4/5, as I love the archeology!
