Bangkok to Koh Si Chang

The fastest way and the easiest way

The van and the speedboat is the fastest, about 2.5 hours. The easiest is your own van to Koh Loi Pier and the ferry, with the van waiting when you get back.

Buses run to Sriracha from Ekkamai or Mo Chit 2, then it's a tuk-tuk to the pier.

How often does the ferry run?

The ferry runs every hour through the day from Sriracha's Koh Loi Pier, 40 to 45 minutes across. Saengprathap (2018) Co., Ltd. runs it.

Cross back by about 5pm to be safe.

Is there a speedboat to Koh Si Chang?

Yes. A public speedboat carries foot passengers from Koh Loi Pier to the island's lower pier in 15 to 20 minutes.

On a day trip it saves half an hour each way.

How far is Koh Loi Pier?

Sriracha is about 105 km from Bangkok, so a van gets you to the pier in about 2 hours, traffic allowing. Bangkok to Pattaya buses stop by the Clock Tower in Sriracha, 2 km from the pier.

Why the group goes by private car

Your own van runs from the hotel to Koh Loi Pier and waits for the return, so nobody hunts for a tuk-tuk with the bags.

• The van: a luxury van for up to 4, a party van for up to 10, or a coach for 20 and more.
• Flying in to Suvarnabhumi? Add our private meet-and-assist service, quoted by Tanner: our host meets you at the gate, using the priority lane where your ticket or status allows.
• The day: leave Bangkok by 8am, on the island by mid-morning, back on the mainland before the last boats.

Ask Tanner to set the day.

The crossing, and the island day

Bangkok to Koh Si Chang is an easy day out. The Koh Si Chang ferry from Koh Loi Pier runs about hourly, about 45 minutes over 12 km of water (checked October 2026).

Take the speedboat to Koh Si Chang on the way out and the ferry back, and you win half an hour on the island. Hire one of the three-wheeled taxis for the loop of the palace and the beaches.

The luxury van for up to 4 is from ฿6,500 for 10 hours, parked at the pier all day. The boats are cheap and paid on the day.

Tanner's pick: out of Bangkok by 8am, lunch on the island, seafood in Sriracha on the way home.

Is Koh Si Chang worth it?

Yes, for a quiet island day close to Bangkok. King Chulalongkorn built a royal summer palace here, Phra Chudadhut Palace, in the late 19th century.

The island is temples, the palace grounds and small beaches, all reached by the local three-wheeled taxis.

Make a day of it: the island, Sriracha's seafood, then Pattaya after dark.

See Sriracha nightlife, Pattaya nightlife and Bangkok to Pattaya, and ask Tanner to run the day into an evening in Pattaya.
