Cenote Jailhouse
Also known as Muknal Remote Siphon, Las Palmas
Location: 20.18850, -87.49010 (Yucatán, Mexico)
The cave really has two parts: one section is fresh water, and very, very dark. The other portion is below the halocline, and very white and cobalt blue. Salt water passage exists on both sides of the T, but the biggest passage is to the downstream side.
Entering the cave, at a depth of 40 ft, you will find a permanent T intersection with two white arrows pointing back to the surface. To the right is the upstream section of the area. To the left is the downstream area. Swim about 250 ft, and you find two offshoot lines on the right side. The offshoot line that heads to the right is a shortcut to the incredible deep saltwater line. The offshoot line to the left is another shortcut line and will take you to the beginning of the saltwater area. Jump across and swim right about 100 ft and then jump left, 50 ft, and you enter the beautiful Swiss siphon passage.
