Dark Cave (Goa Kelam)

This is a real trip, so many trip I has done just only one I love, Dark Cave.
So beautiful and amazing place,I want go to there again because so many patch I didn't catch maybe next time I go to there again.
First time I go to the cave is dark, wet, marvelous, damp, etc. The distance is about 370m.I want to know who build the bridge? But I can't get the answer. The design of it's perfect construction and unique. And I want to know where the places finish of the construction and open for public? I didn't get any information from the guard on it. Maybe Miss Intan can help me to answers my question.
After we go out the cave I saw the river and high ladder to go to the secret place. Why I called secret place? because I can't go to there. Miss Kat told me is too dangerous and we go the other places. On the way to go to the outside, I see a monkey.
Finally, I was to tired but in other site I was happy to see the natural what God (Allah S.W.T) was create it.
