Lighthouse is Havelock's signature reef site, named for the beacon above the bay and known for a clean coral slope that starts shallow and stays interesting through the middle of the reef. The dive runs from a mooring over coral gardens, sand channels, and a deeper end zone, so it works for training, relaxed fun dives, and night diving. Most days are calm with clear water, but tidal windows can tighten the current, so timing and briefings matter. It is also a strong turtle and macro site when conditions line up.
