Yaxchilan on the Usumacinta River

Yaxchilan occupies a horseshoe bend of the Usumacinta and is reachable only by a roughly 40-minute lancha ride downstream from the Frontera Corozal pier, so the river crossing itself is part of the photographic experience, with mist often lying on the water on the first boats of the day. The principal subjects are the labyrinth building at the entrance, the carved lintels of Structures 20, 21 and 33, and Structure 33 itself on its terrace above the river, with howler monkeys roaring in the canopy from first light. The labyrinth's dark passages and the undersides of the lintels need a fast lens and a head torch to navigate and compose in the available light; outside, the river-facing terrace of Structure 33 takes open light through the day. Taking one of the first boats, 08:30 to 10:30, catches both the morning mist on the river and workable light in the labyrinth interior before midday heat builds. January to May is the best season, when the river runs lower and the road to Frontera Corozal is reliable; the rainy season can complicate both the drive in and the river crossing. Handheld photography is unrestricted at the site; tripods require prior INAH authorisation and drones are prohibited. The Chol community cooperative at Frontera Corozal charges roughly 1,500-2,000 MXN (approx USD 88-118) for a boat of up to eight people with waiting time, plus a village access fee of about 40 MXN (approx USD 2), and INAH charges about 100 MXN (approx USD 6) at the site, so sharing a boat with other visitors substantially reduces the per-person cost.
