Yes, Koh Samet is generally worth visiting, especially for those seeking a tropical getaway close to Bangkok, with beautiful white-sand beaches and calm, clear waters ideal for families and couples. While it offers lively beach areas with bars and restaurants, it also provides tranquil, less-crowded bays for a peaceful escape. It's an accessible and compact island, a popular choice for weekend trips from Bangkok, but a flight to a larger island might be better if you're only visiting one Thai island for a longer vacation. The island features numerous stretches of fine, white sand and clear, turquoise waters, perfect for swimming and relaxing. You can find both lively beaches with bars, restaurants, and water sports, and quieter, more secluded bays for a peaceful experience.
