4. Dolina 1 (1.010 mdm) - Ponorului Fortress Cave - Dolina 3 (1.070 mdm)
distance 0,5 km / duration 30-60 minutes / hard / blue dot
Seems strange. Half a kilometer in an hour! It'd be a shame not to make the most of this section of trail. First you stand mute in front of the limestone portal of the main entrance to the Cave of the Ponorului Fortresses. You can walk down the path to the actual entrance through the large 70-meter high portal. The main gallery of the cave measures 2 km in length and is active and very spectacular, with a strong river flowing through it, with a few small jumps. Doline 1 is 300 meters deep and 1 km in diameter.
We follow the marked path, which avoids the cave, climbs some metal stairs, and enters Dolina 3, then crosses a stable gully and reaches the secondary entrance to the Cave of the Ponorului Fortresses. Right next to it this time. Here we read that crossing the cave is forbidden to tourists.
To get out of Dolina 3, especially since the rain has started, we have to climb up a steep and slippery rocky passage, where we can help ourselves with safety chains. The climb ends at the ridge where we meet the yellow point marker again. Break.
