DO NOT MISS THE SIGN!! The sign for purchasing your tickets at the ticketing counter. We didn't see the sign (and actually many other foreigners missed it as well). When we took a hike up to the temple, we had to hike back down to purchase tickets THEN HIKE BACK UP AGAIN!!
Really pretty cave temples, you may choose to buy flowers before entering temples. They had some english speaking guides but we chose to explore the area ourselves.
