The caving activities sound interesting, which I have read about it on NG years ago. Such adventure is really expensive, not for the ordinary people like us. The underwater cave diving must be exciting, probing in the pitch black and narrow spaces require special training.
The caving fun at Vang Vieng (Laos) in 2005 refilled my memory instantly, of course this was just a fun trip. The nervous feeling grew while wading through the shoulder height cold milky water with anxiety of touching unknown exotic insects or spiders or snakes. The complete darkness infused mystery and uncertainty throughout the expedition, definitely not catered for the faint of heart.
I’m planning to go diving at Sipadan Island (one of the world’s top underwater odysseys) and trek inside the world’s largest cave – Mulu National Park very soon. It’s time to explore the beauty of my own country.
