Koh Samet is quite a small island and exploring the island by foot can be very rewarding, if you have the wind for it. Typical island style transportation is used to bring tourists from the pier to their hotels. Scooters are the only means for visitors to get around on their own. Though not recommended in cities or other high-traffic areas, scooters, or mopeds, are a cheap, fast, and easy way of getting around islands like these, small villages and beach towns in Thailand.
At a low cost of approximately 200-500 Baht per day, you can tour around the island, beach towns, highways, and back roads, which can lead to much more interesting adventures than if you simply took a standard tour. Some smaller islands along the Andaman coast have only Scooters. No cars or buses are available, you either have to rent a scooter to get around, or ride a motorcycle taxi for a mere 10-80 Baht depending on your destination.
