Ko Samea San is an island in Amphur Sattahip, Chon Buri. Getting there doesn't take a very long time because the island is not too far from Bangkok. Ko Samae San is under the control of the Royal Thai Navy. Visitors can only have a one-day trip but cannot stay overnight. However, they can stay at the resorts near the pier. Ko Samae San is one of nine islands in the Plant Genetic Conservation Project under the Royal Initiative of Her Royal Highness Princess Maha Chakri Sirindhorn with the objectives of promoting the island as a place for learning and conservative traveling. Visitors can go snorkeling, riding on a glass-bottom boat, kayaking and biking around the island. There are facilities provided such as snorkel sets, life jackets, bathrooms, showers, and restaurants.
