Option 1: Lomprayah Ferry from Koh Samui to Bangkok

This service leaves from Maenam Lomprayah Pier on the North of the island about 25 minutes drive from Chaweng and 15 minutes from Nathon. The Maenam Lomprayah Pier is about 1.5 km from the main ring road around the Island, which means if you take a shared pick up taxi you will need to walk for about 20 minutes to get to the pier.

  • Arrival Point in Bangkok: The Lomprayah Service terminates at the Sip Sam Hang Road which is near the start of Soi Rambutri and 2 minutes from the Khao San Road. To travel onto locations such as the Sukhumvit Road or Silom you need to take a taxi. The Lomprayah service arrives in the evening and in this part of Bangkok it can be difficult to get a taxi to use their meter and charge regular fares. If you plan to use the Lomprayah service it may be more convenient to book a hotel in the Khao San Road area.
