HomeCavernsThe Pit
Description
The entrance fee for divers is 20 USD. No toilets or changing facilities are available. There is very limited parking and no tables to set up dive equipment. Getting in and out of the water is very challenging and requires a high degree of fitness. It is a long walk of approx 300m/990ft from the parking area to the Cenote over a very rocky trail. It is a 6m/20ft drop from the edge of the Cenote to the water giant stride entry to get in. There are no ladders or steps so your guide will show you where and how to climb down and back out at the end of your dive. The Pit has a maximum depth of 60m/200ft in the cavern zone and but the maximum depth allowed for Cavern Diving is 40m/130ft and we will stay within this limit. Halocline depth 18m/60ft.
The Pit
For a long time “The Pit” was a closely guarded secret and very rarely dived due to its remote and inaccessible location. Recently access, although still not easy, has improved making guided cavern dives a possibility.

It is by far the most challenging and adventurous of all the cavern dives on offer but it is definitely worth the effort as it is also probably the most spectacular.

Access is via the Dos Ojos entrance located 1km south of Xel Ha on Highway 307. From the turnoff a 3km dirt road leads out to Dos Ojos and the turnoff to the Pit is a further 15 minute drive into the jungle over quite a rough trail from there.

The Pit is the deepest part of Sistema Dos Ojos which is the 3rd longest underwater cave in the world and is also the deepest cave so far discovered in Quintana Roo with a maximum depth of 120m/400ft. This is a dive for experienced divers because of the depth and good buoyancy control is essential to avoid uncontrolled descents or ascents.

The adventure starts with a hike of 300m/1000ft over a rugged trail to the edge of the cenote. Once there you have 2 choices to get down to the water; a daring 6m/20ft jump or a more sedate but somewhat tricky climb down the side of the cenote.

As you start the dive and descend down through the freshwater the view of the sunbeams lancing down through the crystal clear water is incredible.

Much like Angelita as you descend further you will see an island appear out of a cloud of hydrogen sulphide.

The hydrogen sulphide layer although not as strong as at Angelita is still very impressive with te added benefit that when you descend below you still have ambient light penetration and can see back up all the way to the mouth of the Pit.

As you circle to the back of the Cavern Zone you can still see the entrance ringed by trees and a sheer wall of light across almost the entire width of the cenote all the way from the surface to the hydrogen sulphide layer at 30m/100ft which it light up with a blue tint. Other divers near the surface appear like flies. This is probably one of the most awe inspiring and spectacular site you are ever likely to see while diving.

As you circle the cavern zone you will begin a slow ascent back up past huge stalactites until you reach fairly shallow depths where the vaulted ceiling is beautifully decorated with formations.

The safety stop at the end of the dive will give you the perfect bird’s eye view to truly appreciate the incredible glory and size of the Pit.
