The two viewpoints that are on the island, one 20 minutes from from the village, and the second 15 minutes going up, are the best way to end the day at Phi Phi, with the sun setting on the horizon and panoramic view over the islands. There is a small bar at the top, but they charge the drinks as if you had just climbed to the Himalayas, so if you want to make a cheers at sunset, it is better to bring your own drinks in a backpack with you.
View Point is an unforgettable sight in Koh Phi Phi. The climb is steep and painful, but worth it. The first time I went, it was free, but now it charges 20 baht. Rush hour is before sunset, when everyone goes in search of the best pictures. Beware of the monkeys, which can cause problems ... or at least caused problems for me, because I'm afraid of monkeys! The view from above is spectacular.
