I visited Koh Samui first time on 14th April 2018. It was one day and night visit. Enjoy the Island. Drive Motorbike to explored it. Ko Samui, Thailand’s second largest island, lies in the Gulf of Thailand off the east coast of the Kra Isthmus. It’s known for its palm-fringed beaches, coconut groves and dense, mountainous rainforest, plus luxury resorts and posh spas. The landmark 12m-tall golden Big Buddha statue at Wat Phra Yai Temple is located on a tiny island connected to Ko Samui by a causeway.
