Nadia steps out and almost disappears in the jungle along an imaginary path. When I catch up with her, she proudly presents me the Cenote of the Sun. Whoever named this cenote must have had a peculiar sense of humor - cause the sun can't really be said to illuminate this little crack. But do we love this kind of entrances! Super cool indeed.
The rocks are slippery and it takes some careful maneuvering to slip into the water with 40+kg of gear on our back. Bloodthursty mosquitoes are buzzing around our heads, eager to collect their entrance fee, so we don't loose too much time and quickly let ourselves sink down before running out of blood money.
Soon after descending we meet a T and go right, towards cenote Jailhouse. As expected, the passages are mostly dark here, brownish-black from tannic acid. Speleothems seem to be huddling together in a few places, but otherwise the main attraction here is the halocline located between 15-17m. Especially where the tunnel widens up in spacious rooms, the sight is quite something, like flying just over or below a lake's surface.
46' into the dive we turn around, about 25' away from cenote Jailhouse. It would be possible to do a traverse dive, but that's not our plan, so back we go. The return is against the current, and I can notice it. I only used 50bar on the way in (as planned), but I need 70bar to get out - even though the return trip is actually 5' shorter.
3m away from the surface I pause for a short 7' deco stop. Max depth 20m. Bottom time 92'.
