Friendly if unexciting little PHANG NGA TOWN, beautifully located under looming limestone cliffs edged with palm groves midway between Phuket and Krabi, serves mainly as a point from which to organize budget longtail trips around the spectacular karst islands of Ao Phang Nga. But there are also several caves and waterfalls nearby, accessible on cheap tours run by Phang Nga tour operators.
