Sèche Croissant - Prony Bay

The MUC, or Majestic Unicorn Cove, at the Poor Knights Islands, is one of our absolute favourites for a late afternoon dip. We’d suggest you aim for an hour before sunset, when the light shifts to a warm, golden glow across the sandy bottom. The cove itself is fairly shallow, topping out at around 11 metres, but it offers a surprisingly diverse array of life given its humble depth. We love drifting over the sand, keeping an eye out for sandperch darting into their burrows or the delicate fronds of European fan-worms swaying with the gentle surge. It’s a fantastic spot for macro, with smooth hammerheads occasionally cruising by in the deeper water if you’re lucky, and we’ve spotted spitlure frogfish here too, which is always a treat. Don’t rush it. Take your time scanning the bottom and the rocky edges. The visibility averages around 7 metres, so it’s not about seeing huge distances, but rather appreciating the intimate details close at hand. We find it perfect for photographers and anyone who enjoys a relaxed dive without the pressure of strong currents or deep profiles. Just remember those steep steps from the carpark on the way back up!
