T3 - Perhentian Islands

T3 is one of those Perhentian sites we often swing by when we’re looking for something a bit different, away from the bigger reefs. It’s not about dramatic drop-offs here. Instead, you're meandering over patches of seagrass, which often means you’ll find Green Turtles munching away, completely unbothered. Keep an eye out for the smaller stuff too, like the Blackspotted Sea Cucumbers and the surprisingly vibrant Bicolor nudibranchs tucked in the Branch and Honeycomb corals. It’s a good spot for a relaxed second dive, particularly if you enjoy macro life and taking your time.
