Ybykty Sai is a wild natural gorge that serves as the channel for a seasonal watercourse. Descending here is not a simple walk in the park but an immersion into a closed ecosystem with its own inherent risks. The primary mistake tourists make is underestimating the terrain. Despite the canyon’s shallow appearance, sprains and injuries occur annually due to improper footwear and a lack of attention. To ensure a trauma-free expedition, it is vital to understand the nature of the threats hidden within these picturesque walls.
Why is it so slippery, and which shoes should you choose? The walls and floor of the canyon consist of soft limestone and shell rock. Over millions of years, rainwater and wind have polished these surfaces to the consistency of smooth marble. Even in dry conditions, a fine layer of chalky dust rests on the rocks, acting as a "dry lubricant". If even a light rain occurred the day before, the descent transforms into a literal ice rink. Therefore, flip-flops, city sneakers, or shoes with "bald" soles will lead to injuries. You require trekking boots with a deep, aggressive tread (preferably Vibram) and ankle support. Only such a sole is capable of "biting" into the terrain and holding you on inclined surfaces.
The gorge provides life-saving shade in the hot steppe, attracting not only tourists but also local fauna. Crevices, overhanging ledges, and those beautiful "lacy" apertures often hide pit vipers, Dione's snakes, scorpions, and solifuges.
- The "Watch Your Step" Rule: Snakes are cold-blooded creatures that may lie on the trail to bask or rest. They never attack first unless provoked. In 90% of cases, a bite occurs when a person steps on a snake or approaches too closely. Your primary defense is constant vigilance.
- The "Hands to Yourself" Rule: Never thrust your hands into burrows, cracks, or blind apertures in the walls for the sake of an interesting photograph or out of curiosity. While you see a "pretty hole," a scorpion or snake sees a home they will defend.
- The "Tapping" Rule: If you are leading a group through narrow passages with tall grass or rock piles, use a trekking pole to create vibrations in front of you. This warns local inhabitants of your approach and gives them time to retreat.
The risk of flash flooding is the most serious danger, and one rarely considered by novices. During a thunderstorm, rainwater from the vast surrounding steppe rushes into this narrow gutter. The water level can rise by 1–2 meters in mere minutes, transforming into a violent mudflow. If there are storm clouds on the horizon, descent is strictly prohibited. The water does not simply rise; it approaches as a "wall," knocking you off your feet. In such a narrow canyon, there are no paths for retreat.
