ho do I get from koh san road to thonburi train station to get a bus to Koh Chang

Walk? Hitch hike? Taxi? Private limousine? Make friends with someone who has a car? The possibilities are endless no doubt.

TIS has it right, but he did miss out a tuk tuk ride with a free tour of bangkoks factories and shops thrown in!

Don't know about buses to Koh Chang (are you sure they go from there?...I'd check it on the Thailand branch) but the train station is easy to reach from Khao San Road.

Walk to the river (through Wat Chana at the end of KS road)...go to the ferry stop(Phra Arthit),get a ferry to the Thonburi railway station ferry stop (its only a couple of minutes)...get off the ferry there and walk up the road to the train station.

Havent been to Koh Chang but took a bus to Si Racha from Southern Bus Station.
