Along the east-west road, this temple is one of the most popular and important sea temples on Bali. Proceed with caution if you chose to go. Sunset is the preferred time to visit and is thus teaming with tourists. You have to wade through a row of commercial shops and cafes before you arrive at the temple itself and aggressive touts try to sell you all manner of things. Non-Balinese are not let inside the actual temple. It is best to visit during the day before lunch. You can catch the spectacular sunsets all over the southern coast.
The temple is in Beraban village on a rock that is only accessible at low tide. All of the sea temples were constructed to be in sight of each other and form a chain along the coast. So from Pura Tanah Lot, look to the cliff top of Uluwatu in the distance to the south, and to the other side to the west towards Perancak near Negara.
Pura Tanah Lot is associated with the Majapahit priest Nirartha, who refashioned Balinese Hinduism in the 16th century. It remains an important prayer site and is where followers of the faith pray for the success of their crops and generally anything else associated with agriculture. Farmers in rural areas make pilgrimages to the temple to seek blessings that will safeguard their livelihood, while urban-dwelling Hindu's often visit Tanah Lot in family groups to meditate and seek spiritual guidance. Hidden among the rocks and crevices surrounding Tanah Lot are a number of black sea snakes. Although these snakes are tame, be cautious and refrain from unnecessarily aggravating them or wandering off unaccompanied. These snakes are believed to be the guardians of the temple and protect the entire area from unseen evil forces -- don't let them think you are one of them.
