June 29, 2016 Dos Pisos: A long traverse done as a circuit.
Perhaps the best long dive that Zsolt and I have done on this trip was a circuit at Dos Pisos from the south entrance to the north entrance. We did the dive using a single stage.
Drive south of Tulum on 307. Watch for the mile markers on the left side of the road (yes this is awkward since they face away from you). After you pass mile marker 220 slow down and begin watching on the right for a sign that reads: Dos Pisos. There are two signs. The one by the road is worn and hard to read. Another sign, closer to the tree-bush line, is clearly written. Turn right here.
Proceed into Rancho Campensino following the road to the right past houses and buildings. We paid 200 pesos per person at the houses–a guy was there that came out to the car.
Continue on road that trends left past black, rubber water pools and past several intersections. Watch for the signs (signs at every intersection) but I think we always turned left. Eventually you will come to the end of the road. On the left there is junk: mattresses, pole structures, kitchen stuff, etc.
On the right are tables for dive gear. Park here. The trail starts between the tables and goes about 200 feet down to the cenote. The water is clear and the entry is easy. The cave line starts left of center, and back, in sort of an alcove and is above the water line.
The passage starts in a tube-like structure that extends maybe 100-200 feet with a flat bottom passable by back mount or sidemount-stage and then opens into large, diverse passages–this is a great stage dive.
The main line has many jumps and a few T intersections so bring a lot of cookies. We surfaced in clear water on in the north cenote under broken boulders and could see the jungle beyond the rocks. The traverse is upstream and there is a flow that reminds me of the north Florida cave, Peacock.
The passages have white formations and walls in contrast to a brown bottom and constantly change from one section to the next. In the shallow parts, there were massive root sections dropping from the ceiling.
The dive was over two hours and one of the best dives we’ve had in the Yucatan.
