When you turn into the ruins entrance you have to park in a parking lot and walk in. The one on the right all the way down is 100 pesos. They won’t pressure you into buying anything else. Be ready for the guys when you drive down the street that will try to stop you. They look official but they are just trying to sell you tours. Lots of scammers on the walk in. Good luck 😂

Yes! On each ruin there's an information board, the guides are SUPER EXPENSIVE and UNNECESSARY!!

Ci sono vari parcheggi a pagamento nei pressi della zona d'ingresso dove ci sono vari negozi e ristoranti.. La biglietteria poi, dove c'è il vero ingresso al sito, è praticamente a circa 10 minuti a piedi (volendo c'é anche un autobus che fa da shuttle) dalla zona di negozi e ristoranti.

We self guided, there are boards with details of each building etc. A quick google and I had a map downloaded to my phone. A group of us did the site in just over an hour but you MUST be there for 8:00 -> 8:15 at the latest as the crowds soon start to arrive and it was getting very busy when we were leaving at about 09:45

Unfortunately I’m unsure about this.

tene un costo aproximado de 300 pesos si por persona si los contactas ahí directo en la playa, sería ir a playa paraíso es una buena opción para salir de ahi. Ellos te dan el tour en la lancha y te llevan a la zona y al cenote

I visited last September, and the entrance fee was 80 pesos per person. bringing a camera with you will cost you 45 pesos extra, do show it at the entrance or they will send you all the way back from the point where they check your ticket. And do bring water, after you have entered the park there is nothing available. And it can get really hot because you are in the sun the whole time, hardly any shade at the grounds. Easy to get there by ADO bus, they stop at the site, lots to see before you enter the actual park as well. Enjoy your visit!
