First though we had to find the cenote's entrance gate somewhere along highway 307 north of Tulum. Despite Nohoch's relative fame & popularity, none of the locals were able to help us out, but again memory served me well: the access road is the same as for Caracol!
From the parking & gearing up area it's a hot walk down to the 24°C cool water. Equipment checks done we submerged and went looking for a line, which we found at the end of the cavern zone and followed till its end barely 26' later, requiring us to close a gap to another line passing by just a few meters away. On my sign we went left, passing a domed cenote then approaching another brighter one. Both with snorkelers? Too much human activity for me so we swam back, shortly checking out the right section after the gap, thereby finding ourselves immediately in a fabulous area of petrified waterfalls.
This wonderful cave system is amazingly vast and very very shallow, averaging around 5m depth, thus allowing for extended dives of up to two hours on just a set of doubles.
* After talking to Robbie from Xibalba, who alas wasn't there when we got going, I found out that there are actually three upstream and one downstream line, and that by going left at the gap we indeed most probably made a circuit back to where we'd started.
