onsai Bay is the main arrival and departure hub for Koh Phi Phi. Ferries come and go, yachts anchor, dive and tour boats pick up their customers and longtails whiz back and forth carrying passengers or goods. Tonsai Village, the main village on Phi Phi Don is located here as well. While it initially appears a scenic spot on arriving at Koh Phi Phi, the water at Tonsai Bay tends to be quite polluted and there’s a fair bit of boat traffic continually coming in and out of the bay. Still, it’s a fun place to look around and enjoy the activity.
