Me and my girlfriend went as part of a tour booked with chichen itza so arrived here at a time where it was really busy.
However, it did not bother us as plenty of space to take photos and enjoy ourselves as we experienced our first cenote.
The cenote has a few platforms to jump into the water from in which you can then choose from how high you want to jump from. The place is amazing and they offer lifejacket for something like 1 dollar if you need them.
Really enjoyed my time here but would recommend arriving early as most people arrive around 12am.
