Quick answer: Koh Pak Bia (Pakbia) is a tiny sandbar between Koh Yao islands in Phang Nga Bay. It appears on many Phuket jet ski island tours and some speedboat routes — shallow turquoise water, photo stops, and short beach time.
- Best visited on calm mornings (Nov–Apr peak season)
- Usually combined with Khai, Chicken Island, or James Bond on multi-island days
- No facilities on the sandbar — bring sunscreen and water
