Koh Samet FAQ

Is it worth visiting Koh Samet?
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.
How do I get from Bangkok to Koh Samet?
To get to Koh Samet from Bangkok, take a bus or minivan from Ekkamai Bus Terminal to Ban Phe pier, which takes about three to four hours, followed by a ferry or speedboat to the island. Another option is to take a combined transport ticket that includes both the bus and boat journey. You must pay a National Park entrance fee upon arrival at the island. The bus or minivan ride to Ban Phe takes approximately 3-4 hours. You can buy tickets at the bus terminal or book combined bus-and-boat packages online in advance.
Can you walk around Koh Samet?
Koh Samet is a small island, and if you live in the main town of Na Dan or on the main beach Sai Kaew Beach, you can easily walk around. On the main street there is even a sidewalk. If you're staying at one of Koh Samet's other beaches, it's best to either rent a scooter or use the songthaews, which function as local buses, to get around.
Is Koh Samet a quiet island?
Koh Samet can be quiet and relaxing on the weekdays, offering a peaceful escape. However, it becomes more lively and fun on the weekends due to its popularity as a getaway destination for people from Bangkok. Despite its proximity to the city, it remains a beautiful island with powdery white sand, generally great year-round weather, and a variety of lodging options.
What are the main attractions on Koh Samet?
Koh Samet is renowned for its stunning beaches, with Sai Kaew Beach being the most popular and lively. Other notable beaches include Ao Prao, Ao Wai, and Ao Kio Na Nok, offering different vibes from bustling to secluded. Visitors can enjoy swimming, sunbathing, snorkeling, and various water sports.
