Koh Similan Lighthouse

8° 38.0′ N · 97° 38.9′ E

The major light on Koh Similan that guides overnight passages from Phuket and Thap Lamu into the group.

Practical

Charted as Fl 20s, nominal range 17 M (OSM seamark data). The Southeast Asia Pilot says it is reliable and visible from about 15 nm on an overnight passage. Use it to time a dawn arrival at the Donald Duck Bay anchorage; do not enter the anchorage in the dark, because it is full of moored dive boats and unlit coral heads.

Best for

Landfall for night passages from Phuket
