About Criminal Rock
Criminal Rock is a north-east Praslin boat dive built around submerged granite and broken passages, with swim-through-style structure and regular fish movement. The run depends on weather, so it suits divers who are happy with operator-led logistics and a site that can feel different as sea state changes rather than a simple flat reef.
