I just got back from a weekend in Kending, and I’d like to recommend a good contact:
George (didn’t get a last name), just outside of Nanwan was a HUGE help to us as we bumped around the area. He helped my wife find a place to stay when everything was sold out. My scuba experience was great in no small part from his efforts. While I was diving he drove my wife and son to a glass bottomed boat tour, then waited for them to be finished so he could take them back to the dive shop to meet me.
His cel number is: 0925 776 375 (speaks great English too)and there’s a website (all in Chinese) with more contact info:
