The rock temples are not exactly located by the parking lot: you'll still have to walk uphill 20/30 minutes - over a path or some stairs. it's neither long nor difficult but... you'll be sweating a lot. So be warned: wear appropriate shoes and bring plenty of water or you'll visit will turn into a miserable time.
There are a lot of monkeys near the Dambulla Cave Temples.
Be cautious. Wild animals are always unpredicable no matter how friendly, cute or "just like people" they might seem. We didn't actually see anyone feeding these monkeys but it probably happens because one monkey thought my husband's bag belonged to him and tried to take it.
No matter how unlikely getting bitten by a monkey might be, getting treated for a one is probably not how you want to spend your vacation.
By afternoon, the stone in front of the Dambulla Cave Temples is very hot.
As at most Sri Lanka cultural and religious sites, shoes, hats and uncovered legs or shoulders are inappropiate and not allowed.
It is possible to walk along the sheltered path right next to the cave entrance but if you want to wander out onto the "plaza" to see the view, you will want socks. My tootsies were very un-comfortable while I took this photo.
