Serpent Rock - Poor Knights Islands

The Slide at Terrigal is one of our favourite shore dives on the Central Coast, especially when the conditions are just right. It's a relatively shallow site, dropping to a maximum of 13 metres, which means you get some decent bottom time if you're good on air. We love the way the reef starts as a gentle slope of boulders and rocks, then around 13 metres, it really drops off into these incredible sponge gardens. That's where you'll find the nudibranchs, and we mean a lot of them. Seriously, keep your eyes peeled; some days you can spot dozens of different species on a single dive. Visibility averages around 7 metres, so it's not always crystal clear, but that just adds to the hunt for macro life. Look for the Australian Spiny Pipehorse tucked into the sponges, and we’ve often seen schools of Australian Salmon or Kingfish cruising by in the blue. For a shore dive, it offers a surprising amount of invertebrate life and larger pelagics too. It’s perfect for keen photographers or anyone who enjoys a slower, more deliberate dive, scanning every crevice.
