Ok, the door, I can not open, BUT, I found out that it is possible to get on TOP of the Temple lol. Just goto the sides by where the two snakes are, you see two pillers (small ones close together) just angle your view up, and start jumping, next thing you know, your walking up onto the roof! hehe. Just dont fall off the back, otherwise your trapped in a pit, which I found an arrow hehe. Anyone want to add anything to this?

Nice view, eh??

If you are trying to enter - look for a back door (you'll have to swim)
