What is the company that runs "Underground River" excursion in Playa Del Carmen?

A couple of years ago, we did an excursion while on the Magic called "Underground River and 5th Avenue Shopping Excursion". We had a blast doing it. This year, we're headed to Playa for a couple of weeks but not on a cruise. Does anyone know if it possible to visit that Cenote or go on that excursion if not on a Carnival cruise? Does anyone know the company that runs that tour so I could contact them? Thanks for your help!

It's called Rio Secreto.

Nope, different excursion.

We did the Underground River with 5th Ave shopping on a Carnival cruise. Another group (seated with us at dinner) did the Rio Secreto. Different cenotes, different type of excursion. Our Underground river was totally in the dark and you have to swim/tread water the whole time as water is over your head. The tour they did was with a hard hat on and had to walk through caves with cenotes. They were never swimming.
