Surat Thani: Gateway to Koh Samui, Koh Phangan & Koh Tao

The Surat Thani ferry system operates from two distinct departure points that serve different island combinations and are frequently confused by first-time visitors. Don Sak pier, located 70 kilometres east of Surat Thani town, is the main vehicle and passenger ferry terminal serving Koh Samui and Koh Phangan. The Seatran Discovery and Raja Ferry both operate high-capacity roll-on/roll-off ferries from Don Sak throughout the day, with departures typically running every 90 minutes from early morning until late evening. The crossing to Koh Samui (Nathon pier) takes approximately 90 minutes; the crossing to Koh Phangan (Thong Sala) takes around 2 hours. A second option from Don Sak, the high-speed catamaran operated by Songserm, reduces crossing times to Koh Samui to 45 minutes but charges a premium and carries no vehicles. The older Ban Don pier in central Surat Thani town historically served as an alternative departure point for night boats to Koh Samui and Koh Phangan, though schedules here have reduced in recent years — confirm current availability when planning.

For Koh Tao, the routing becomes somewhat more complex. The most common approach is to take the ferry from Don Sak to Koh Phangan and then transfer to the catamaran service that runs onwards to Koh Tao from Thong Sala pier. Alternatively, the Lomprayah high-speed catamaran operates a Surat Thani to Koh Tao service (via Koh Samui and Koh Phangan) that departs from the Lomprayah jetty near Ban Don — check the current schedule as this can vary seasonally. The full journey from Surat Thani to Koh Tao takes a minimum of 3.5 hours by the fastest combination and closer to 5-6 hours by the standard ferry route. Budget travellers should factor in that the price difference between standard ferry and high-speed catamaran is rarely more than 200-300 THB — the time saving is significant enough that the premium is usually worth paying.

Combined bus-and-ferry tickets sold from Bangkok's Khao San Road, Hua Lamphong station, and Southern Bus Terminal represent one of the most convenient options for travellers arriving from Bangkok. These packages bundle an overnight bus journey from Bangkok (approximately 11-12 hours to Surat Thani), a transfer vehicle to the ferry pier, and the ferry crossing in a single ticket ranging from 600-900 THB depending on the operator and destination island. The overnight bus is a reliable choice: modern coaches with reclining seats depart around 6-8 PM and arrive in Surat Thani in the early morning, timing the connection conveniently with morning ferry departures. The alternative — the overnight train from Hua Lamphong or Bang Sue to Phun Phin (Surat Thani's railway station, 14km from town) — takes longer at 13-14 hours but provides a considerably more comfortable sleeping experience in second-class air-conditioned berths for a similar total cost.

For travellers with a half-day or full day layover in Surat Thani between transport connections, the city provides more genuine interest than its reputation suggests. The Talat Kaset night market, the Ban Don waterfront oyster stalls, and the nearby Khao Tha Phet monkey temple can all be reached within 20-30 minutes of the town centre by songthaew. Left luggage is available at the main bus terminal at Talat Kaset for 30-50 THB per bag, and at the Surat Thani train station at Phun Phin for a similar rate. The main songthaew routes from Surat Thani town to Don Sak run every 30-45 minutes and cost approximately 50-60 THB per person.
