Pillarsteen

Pillarsteen, located in Indonesia's Kabupaten Manggarai Barat, East Nusa Tenggara, is a remarkable dive site known for its breathtaking topography. With dramatic walls, stunning swim throughs, and impressive whip corals, this site offers a memorable underwater experience. However, it's important to note that Pillarsteen lacks shelter from the swell of the Indian Ocean, resulting in surge conditions. Advanced and expert divers will appreciate the thrill this dive offers.

When the swell is calm, divers can enjoy excellent visibility of up to 17m and encounter a diverse range of marine life. From sea apples and whip coral partner-shrimp to devil rays, snapper, stingrays, manta rays, barracuda, and scorpionfish, there is an abundance of fascinating creatures to discover.

Exploring Pillarsteen is like embarking on an exhilarating journey, also earning it the nickname of "surge city." Despite the challenging conditions, the site's captivating macro critters and the possibility of encountering large marine animals make it a worthwhile experience. So, keep a keen eye on the blue depths, as you never know what majestic creatures might pass by.

Remember, Pillarsteen is best suited to advanced and expert divers due to its unique topography and surge conditions. Plan your dive accordingly and revel in the wonders of this Indonesian dive site.
