I managed to overcome my fear and crawl through a dark hole, too, to get to the Ko Phi Phi viewpoint - sadly, the weather was very dull, so the colors are not that vivid. It's still visible that the color of the water is different in the two bays. Beautiful view that was well worth passing spiders and crawling through a dark hole on the path.
While trekking in the jungle, we had to pass underneath this beast. Although it's not obvious in the picture, this spider was bigger than my entire hand and it was only thirty centimeters above the path. I must admit, this was the time when i considered going back to the beach.
