Actually we didn't have a look on these islands so much because at Koh Pa-Ngan we just went to full moon party all night then slept at an awsome hotel up on the mountain so we could see the sun goes up then we took the ferry to Koh Tao and didn't walk to all area there either because we did snorkeling and in the night we went to The sunset bar...omg this is amazing bar, it was so much fun there, nice foreigners to be friends and fire show was so great. PS. this trip we met an australian stranger by accident on the ferry to Koh Samui but finally he is our friend and joined us on this trip. For this trip 3 nights 4 days we slept less than 15 hours because we went to bars and parties so that;s why we stayed up late and slept less but we were worth it too much. And the last day we went to Khao sarn road to met up with one of our frind(Ratree) because it's been a long time that we no see her.
