Overview
The Ao Po Grand Marina–Koh Yao Yai route is a maritime transport connection in southern Thailand linking Phuket’s northeastern marina facilities with Koh Yao Yai, one of the largest islands located within Phang Nga Bay in the Andaman Sea. The route functions as a key sea access corridor supporting inter-island connectivity between Phuket and communities on Koh Yao Yai.
Route / Location Description
Ao Po Grand Marina is located on the northeastern coast of Phuket, facing the sheltered waters of Phang Nga Bay. Koh Yao Yai lies to the east of Phuket between Phuket and Krabi Province. The route generally travels eastward or southeastward across coastal bay waters from Ao Po Grand Marina toward various landing points on Koh Yao Yai. The crossing distance is moderate compared with short offshore-island routes near Phuket but remains significantly shorter than long offshore Andaman Sea crossings.
Operations and Seasonality
Marine transport services between Ao Po Grand Marina and Koh Yao Yai operate throughout most of the year. Operations generally take place in the relatively protected waters of Phang Nga Bay, which are less directly exposed to open-ocean conditions than routes heading into the outer Andaman Sea. Services may still be influenced by seasonal weather changes, particularly during the southwest monsoon period, when schedules and operations may be adjusted according to safety and sea conditions. Transport is typically carried out by speedboats and passenger vessels operating scheduled or organized services.
Typical Travel Time
Typical travel time between Ao Po Grand Marina and Koh Yao Yai commonly ranges from approximately 20 to 40 minutes, depending on vessel type, exact departure and arrival points, and prevailing sea conditions.

Historical or Development Context
Regular marine connectivity between Phuket and Koh Yao Yai developed as maritime infrastructure in Phang Nga Bay expanded and as northeastern Phuket evolved into a significant marine transport hub. Ao Po Grand Marina became one of the important departure points for structured passenger movement toward islands within the bay, including Koh Yao Yai.
