Directions from Pattaya: 

From Pattaya Klang turn left on Sukhumvit heading north and get onto HWY 7 toward Bangkok.  Keep traveling north on HWY 7 until you pass the 15 km distance marker (marker numbers decrease in this direction) and exit left approximately 500m past the marker (you will also see signs for Khao Kheow Counrty Club directing you to take this exit). Then, make a U-turn and take the overpass bridge (flyover) back across HWY 7 heading east for 1.8 km until you come to a 4-way intersection without a stop sign.  At this this intersection you will see a blue sign pointing straight toward Khao Kheow Country Club (see attached photo 1). Go straight through and follow this road (Pong Din Dam Reservoir Road, attached photo 2) for 2 km.  Do not go into Country Club entrance.  Continue to follow the asphalt road for another 1.6km as it bends to the right.  At this point the asphalt road makes a sharp left.  A few tens of meters past this point is the "dam" for Ping Din Dam Reservoir.  Continue for another 350m straight until the asphalt road dead-ends into a sand/gravel quarry which is the "A" site.  Total distance from Pattaya Klang is approximately 51km.

Directions from Bangkok: 

Take the Bangkok/Chonburi motorway (HWY 7) heading south towards Chonburi.  Zero your tripometer at the Phan Thong toll plaza (this is about 85 km out of BKK).  Continue south on HWY 7 (which includes the RT 36 by-pass) for approximately 21.9km and exit left (you will also see signs for Khao Kheo Counrty Club and Khao Kheo Open Zoo directing you to take this exit).  Then follow the directions above to the "A" site.  This is really quite simple but if assistance is needed, use the mobile numbers below!
