Visiting these ruins and museum is like a trip to the past. I recommend visiting. There is also a cenote where you can swim after the tour. The cenote is 60 mts. deep in the deepest part and has a shallow part for non-swimmers, it is wonderful to bathe in its water which are cold at first but nice after.
Its importance is astronomical, in terms of greatness, but also astronomically speaking. The position of the ruins of the temple called the 7 Dolls is mathematically perfect. Its orientation allows light beams to cross through their doors and windows such as equinoxes and solstices, a real astronomical machine. But best of the ruins is the dip one can take in the cenote of Xlacah.
I’d recommend it if you have a few hours to spare. It is really close to the city. You can actually take a cab and have it wait for you outside if you’re not planning on swimming.
I did find the entrance a bit expensive though.
