It is worth seeing, specially if you are into architecture. The construction is magnificent. Also if you are catholic you fill find it a very comforting place to pray.
Beautiful, must see place. Wat Arun stands out from other temples and it's worth to visit with a guide who will give you much information about history of the place.
Pretty temple, free entrance, women have to cover shoulders and knees. When I was there it wasn't too busy, the atmosphere was very pleasant to walk around.
There are three levels with temples and the statue on the top. Beautiful views and quiet atmosphere, unless you're unlucky enough to experience the flood of coaches with tourists...
