Grotta del Bivio ad H

Slipping through the narrow opening of Grotta del Bivio ad H, you feel a chill. The air is damp and heavy. This isn’t just any cave. Grotta del Bivio ad H is a vertical plunge into the heart of the Trieste Karst. The cave’s name, “Bivio ad H,” refers to its location near a crossroads shaped like the letter “H”. It’s tucked away just off the SS 202 towards Padriciano, hidden in the woods behind a small parking area. Don’t let the unassuming entrance fool you. Grotta del Bivio ad H descends deep into the earth. It boasts a surprising depth of 45.5 meters and a total length of 71 meters. Imagine the thrill of the original explorers. They had to painstakingly widen the small entrance to even begin their descent. Picture them carefully navigating the initial 14-meter pozzo. Then squeezing through a tight passage before reaching the next 13-meter drop. At the bottom, a series of small climbs lead to a descending tunnel. This tunnel opens into the final 14.5-meter pozzo. This final descent leads to the cave’s deepest point. The cave isn’t just about the thrill of the descent. It’s also a testament to the power of water. During rainy periods, water percolates and drips through the cave’s ceiling, creating a constantly changing environment. Interestingly, despite the depth and confined spaces, a noticeable airflow circulates throughout Grotta del Bivio ad H. This unique feature adds another layer of mystery to this subterranean world. One can only imagine the secrets hidden within its depths.
