Many thanks to Lynne Flaherty for her overview of this system

Access to the system is through a gate just a few hundred yards past the Grand Cenote entrance, but on the other side of the road. The key can be obtained at Xibalba; entrance was 150 pesos per person. There is a caretaker at the site who was present much of the day.

There is one table, but no restrooms. Entry is via a set of stone steps leading to a clay slope, which gets a little slippery when wet, but not bad. The open water area is small. The main line comes out to open water, and is tied off on a stalactite somewhat on the right of the cave opening.

The cave is small and winding and has a lot of minor restrictions, and a LOT of straight up and straight down. It's very decorated and very pretty. Although we didn't swim them, it is my understanding that most of the offshoot lines are sidemount only. It is a very doable dive on one stage, to reach the Box Chen cenote and return.
