It is a very nice cave. For sidemount cave divers only. Quickly enough the cave goes to 20 meters of depth till the first restriction. If you are strong enough and pass it, the cave goes to 12 meters of depth till the second restriction. It took 2.5 hours of hard work for me to make the second restriction penetrable with nomount. After the cave goes vertically down till 20 m again… The rollercoaster begins here)).
