Boat-access Gili Air macro reef with sandy slope and coral pinnacles.
Hans Reef is a boat-access macro reef on Gili Airs north-eastern tip, built around a gentle sandy slope, coral pinnacles, and small bommies. It is best as a slow, detail-rich scuba site where the reward is patient searching over sand patches, coral heads, seagrass edges, and night-dive life rather than long swim distance. Keep the plan tight, watch the flow, and let the reef reveal itself one section at a time.
