Unfortunately the temple itself cannot be visited. You can only approach the steps, however, you need to beware of the tide and the waves.
Pura Batu Balong is another small temple that you can see in the same location.
The area is quite big with beautiful gardens ,statues and other buildings.
It is indeed a very popular sight, like most on the island , so be prepared to be surrounded by tourist ,who just like you want to take the best picture.
