** The above coordinates are for the 'western' entrance, where there is toilet, rain water tank, and an arch. **
This is a 'through cave' with quite a few side tunnels, and many formations.
Lots of evidence of flooding within the cave. [Explaining the absence of the geocache.]
** There are a couple of rickety [bamboo] ladders, so if you are on the 'larger size' please apply CAUTION. **
The coordinates I took for the other side of the through cave are:
N14° 49.572' E100° 45.445'; which I assume is where the geocache is wanting you to go. This is just up the hill from a small monastery.
There is a covered, and fenced-off [sink-]hole in the ground at N14° 49.584' E100° 45.456'. These are near the Wat Pa Suwannahong compound that was being built while I was there. Also where I got an 'Engrish speaking guide'/monk to show that entrance, which I would NOT have found using just the geocache description.
The 'western' side of the cave can be accessed by going to the Peacock Temple from Lopburi, and then head southeast, east, and then south east-east along a rough track which then heads east to an unimproved 'picnic area' with a toilet, and the 'entry arch' shown in the Waymark photo.
** Not far down into the cave (either end) you will come across a bamboo ladder, and you will have to make your own assessment as to whether you can safely use it. (Don't forget that the majority of Thai 'nationals' are a lot smaller than tourists!)
Considering that NONE of these coordinates match up with (
visit link) you 'may ask', "How on earth do you match it up?" Well, I spoke with the monk that guided the other geocacher to this cave, and went through with him!
* I had left my hired motor scooter at the Peacock Temple Freestanding Arch / gate on the Sunday night ~1800, about 800 metres from GZ. With a couple of torches I then tried to find the western entrance of the Treasure Cave. I gave up at 9.15 pm when I was 75 metres away 'from the cache', but found myself on a limestone kaarst cliff under moonlight.
I came back the next morning (from the 'Sunflower Fields'), as I had 'found a track' on my return to the motor scooter, which went through the Peacock Temple compound. I found the origin of the foot track, and rode the scooter to the western end of the cave. (This entrance photo, taken on getting back to the scooter)
However at that time, I didn't recognise that the arch held the entrance to the cave I was looking for, and explored one to the north, that didn't go in far.
Then I scouted around to the south, and then east to find the 'Main Entrance'. This is semi-open, but steep scree slope, until I came across some buildings of the small monastery and the covered sinkhole. It seems that they are used to having visitors wander through, as one of them (that spoke English) asked me to join them for 'breakfast'. With another geocacher being there just two days before I guess I wasn't something too unusual! He pointed in the general direction, but after I mentioned that I had only found the covered sinkhole he agreed to take me to the entrance, and to guide me in. After being shown it by the guiding monk from 'Wat Pa Suwannahong' we found an up-turned 'Golden Turtle', which of course we turned the right way up, and placed it outside the cave entrance.
Together we explored many of the side tunnels, but only found evidence of flooding. Then when we got to the western side, and I exited I was surprised to see the arch of the Waymark photo, and knew the motor scooter was only ~50 metres away. I went back through with the monk as his and my secondary torches were getting dim, and I wanted to make sure he got out!
With another thorough [hour long] search I was content that the cache was 'no more' and re-exited to find the scooter safe and sound. [Grateful for the Thai-basic toilet]
