Trang in southern Thailand. Trang has many attractions that are natural. A culture and a lifestyle that is unique. Attractions in Trang where I was going. Koh Mook and Morakot Cave. I want to go to Koh Mook and Morakot Cave lot. It is a sea cave caused by natural wonders and beauty very much. Light from the outside is reflected off the water inside the cave to see the water is emerald green. Koh Mook with clean sandy beaches, ideal for a vacation.
