Jemeluk Secret Wall - Lombok & Gili Islands
Mathesons Bay is a spot we usually hit when the wind picks up a bit, or when we just want a relaxed dive that still feels like Poor Knights. It's properly sheltered, a calm contrast to some of the more dramatic outer walls. We always enter from the beach; it’s just easier, though you can scramble over the rocks at high tide if you’re feeling adventurous. The whole bay sits pretty shallow, topping out at around 7 metres. We often find ourselves just floating above the kelp and rocky reef, watching the triplefins dart around. The visibility averages about six metres, which, for a sheltered bay, is decent enough to really focus on the smaller stuff. We’ve had great luck spotting blackfoot pāua clinging to the rocks and green rock lobsters tucked into crevices. Keep an eye out for stingrays gliding over the sandy patches; they're pretty common here. It’s perfect for a long, slow dive, especially if you’re into macro life or just getting comfortable again after a break.
