Sac Aktun downstream to the Twister restriction
The Grand Cenote is well known for the upstream decorated cave passages like the Paso de Lagarto and the Cuznha Loop, but the downstream section has a completely different vibe. It is dark, silty very decorated but with stalactites that look like cement, very weird and ominous atmosphere as if it was a totally different cave system. There are numerous restrictions the further in you get some requiring sidemount.
