I have to comment on the transportation services too.
It is not a guided tour you do not need one , it is more walk around at your own pace.
These strenuous activities are rewarded by sights of some really amazing rock formations.
The tunnel of the cave runs from the east to the west covering a distance of about 2km under the limestone hills known as Gunung Tempurung and Gunung Gajah.
We chose the Tour 2,which takes you approximately an hour or so to walk around the cave.
And you should not take young children along on this one! Waterproof phone pouch is also recommended so that you can take pictures.
