Traced from the OnlyCenotes 'Cenote Concha' survey v2.0 (Picard and Newell, December 2024, via cave-ha.com); the map has no scale bar, so it was scaled from its 'distance from entrance' labels in feet (fitted along the traced line, within a few percent). Depths are the underlined feet converted to metres; end labels are penetration from the entrance in metres. The line to Cenote Fenomeno is not on the Concha survey and comes from the OnlyCenotes Fenomeno upstream map (232 m from Fenomeno); the Concha Siphon, Fenomeno South and Las Golondrinas lines beyond the sidemount restriction at 229 m (another 204 m to the siphon) are left out. Gaps between line ends on the source are drawn as jumps. Positions are approximate.

La Concha is entered through a narrow gateway in the rock that drops straight to 10 m — there is no basin to sort yourself out in, the dive starts at depth. Maximum depth is only 10–12 m, and there is roughly 2 500 m of line.

It is decorated throughout: columns, stalagmites, stalactites and helictites, and unlike a lot of the jungle cenotes the water here is dependably clear rather than seasonally tannic. It connects to Fenomeno.

Same track as Fenomeno, Nariz and White River — the 54 km mark on the federal road, then 8 km of dirt. Two dives, 26 February 2025, to 13.4 m.
