    StandoutExceptional marine biodiversity

    Blue Lagoon, near Lombok's Sekotong Peninsula, might not have the dramatic drop-offs of the Gili Trawangan sites, but it's a stellar spot for those who appreciate the smaller, stranger things. We love dropping onto that bright white sand, a real contrast to the vibrant reef on the edges. Maximum depth here is 18m, making it perfect for a leisurely hour of searching rather than racing. You'll spend most of your time scrutinizing the coral bommies and the rubble patches, which are surprisingly rich. We've seen leafy scorpionfish melt into the background, spotted hawkfish perched on corals, and blue-ribbon wrasse darting between crevices. It's also a reliable place for turtles – green and olive ridleys cruise through, often ignoring us completely. Keep an eye on the sandy slopes away from the reef; that's where the cleaning stations are, and we've found blue-spotted stingrays half-buried, along with the occasional Indo-Pacific tarpon making a pass. Visibility averages 16m, which is usually plenty for macro hunting. It's a calm site, great for photographers or anyone who just wants to slow down and really look.
