Eastern Arch

Eastern Arch at the Poor Knights is one of those places that genuinely feels like stepping into a different world. We usually drop in on the western side, where those kelp-covered boulders start around 18 metres. It’s a good spot to get your bearings, maybe spot a Striped Triplefin peeking out. But the real show starts as you push through the arch itself. The walls here are steep, covered in colourful sponges and those tiny nudibranchs if you slow down and look for them. We often feel a slight surge here, a reminder of the open ocean just beyond. Exiting the arch, the wall just drops away into a deep blue, often hazy with schools of fish like Allison's Tuna or California Yellowtail. It’s a prime spot to look out for something bigger cruising by, even a Bronze Whaler if you’re lucky. We love the contrast between the intimate arch and the vastness of the open water. This site really suits divers who appreciate dramatic topography and enjoy the thrill of a big blue encounter.
