How to go to Gua Tambun, Perak?

My husband and I have decided to go to have a look at the Gua Tambun, Perak. But, we don't know how to go to Gua Tambun. So, we search the internet. But, there was no map or instruction to lead us to Gua Tambun. Lastly, we found a blog saying that the Gua Tambun is just behind the Tambun Caltex Petrol Station. Then, we used our GPS to find this petrol station. There we found the petrol station. But, where is the entrance for the Gua Tambun?

We drove into a junction after the petrol station. We saw this signboard below. It is actually "PANORAMA TAMBUN PERDANA". I didn't managed to capture the signboard properly :P

Then, we were in a housing area where we found lots of Indian people staying there. We decided to ask the one of them. The old Indian guy told us that the Gua Tambun is just 500m from this housing area. But, car can't go through. MUST WALK.  If you see the road sign  "SELASAR TAMAN TAMBUN" as below, it means that you are in the right track.

Turn around, you will find this sign right in the corner of the wall. Not very clear instead.

After that, you have to climb over the wall like me.

You will see a horse stable in front of you. Well, keep on walking along the cave.

Finally, we saw this sign. "Gua Tambun".

 Unfortunately, the gate was closed but not locked. Since there were no others here. We decided not to go any further. It looks creepy to us.

Somemore, the bridge is broken.

I wonder why there was no any maintenance at this historical area. I hope to see the Neolithic drawings so much!

I want to see this.
