    Calypso Bay, tucked away in the Poor Knights, feels like one of those places you stumble upon and keep to yourself. We love that it’s often overlooked, giving you a chance to really soak it in. You’ll drop onto a steep rocky wall, thick with a surprising tapestry of sponges and anemones, then follow it down as it morphs into a bouldery slope. Below about 15m, the kelp starts to dominate, swaying in the gentle surge, making for some dramatic light shafts on a sunny day. It’s not about big pelagics here, though a bronze whaler or barracuda might cruise past in the blue. Instead, it’s about the smaller, intricate life – the little banded cleaner shrimp tucked into crevices, the iridescent clown toados darting between rocks, and those tiny blue-eyed triplefins guarding their patches. We find the nudibranchs here particularly vibrant against the dark rock. For photographers, especially macro fans, it’s a quiet gift. Max depth here is 18m, so it’s a calm, easy dive for anyone who prefers a more relaxed pace and an eye for the details.
