Terrifying moments in a cave in Thailand flooded with water! Khao Siwa Water cave

Today I wanted ADRENALINE and I chose a 4 hours drive to the province of Sa Keao, to explore a cave called Khao Siwa Water ( a cave flooded with water and full of bats ).
We had a wonderful guide who guided us where to go / swim through the cave.
I expected a more "accentuated"nadrenaline because we are in the rainy season!
It is a cave with water flowing all year round.
The cave is 450 meters deep, with a water level between 10 - 220 centimeters.
Inside there are many stalactites and stalagmites!
Some areas look like curtains and there is also a small waterfall inside th ecave ( namtok noi ).
It is suitable for those who like adventure and know how to swim.
Required equipment: waterproof clothings, rubber raft and swimmining tubes or life jacket.
Be careful thae the cave is just a few kilometers from the cambodgian border and there are many army filters on the way.
Entrance fee: thai 50 thb, foreigners 100 thb ( + tips for the guide )
