Bukit Kayu Hitam is a town in Kedah, Malaysia.
It is the main road crossing between Malaysia and Thailand and most long distance buses between the two countries use this checkpoint. The Thai checkpoint is officially known as the Sadao Immigration Checkpoint while the town immediately after the border is called Dannok.
There is not much of a town to Bukit Kayu Hitam which locals like to refer to with its loose English translation "Black Forest" - just a few shops located on a side road off the main highway. Most commercial activity is actually centred at the busy duty-free shopping centre located between the Malaysian and Thai checkpoints.
Bukit Kayu Hitam is the northern starting point of the North-South Expressway Expressway code E1 which runs all the way south to Johor Bahru, passing through Kuala Lumpur.
