The actual border is located at Dannok town 10km south of Sadao town and about 60km from Hat Yai. Thai immigration formalities (which is officially called the Sadao Immigration Checkpoint) used to be conducted at Sadao town but has since moved to Dannok just before the border gate into Malaysia. The town on the Malaysian side is Bukit Kayu Hitam.
This road crossing is the busiest between Thailand and Malaysia as both Thailand's National Highway 4 which runs all the way to Bangkok via Hat Yai and Malaysia's North-South Expressway which spans the length of the peninsular to Johor Bahru via Kuala Lumpur start from this crossing. Most long distance buses between Singapore , Malaysia and Thailand use this crossing.
Sadao town is the capital of Sadao district. It is basically a junction town where people heading to Padang Besar turn off National Highway 4.
Dannok, which used to be just a few shops clinging on to both sides of the highway just before the border gate, has grown tremendously over the last few years, mostly fed by people crossing the border in search of sleaze and shopping. On both sides of the highway many little lanes lined with karaoke bars and nightclubs, with scantily-dressed bargirls sitting outside.

In Dannok, vans leave from in front of 7-Eleven to Hat Yai via Sadao town when full. Takes one hour and you can ask to be dropped off anywhere in Hat Yai. The fare is 55 baht, after 11pm you probably won't get a ride for less than 100 baht. In Hat Yai, the van leaves from The Plaza, just across from the TOT offices.
Actually they leave from several places in Hay Yai not only from one, the best is when you come into Hat Yai ask your bus driver to drop you at one. When you come in at the bus terminal just ask one of the motorbike taxi they bring you there for Baht 60,-. The thing is until about 6pm there is a minibus at the bus station going south to the border, after the bus leaves from a totally different place in down town price around Baht 70,-. If you come from lets' say Phuket or Krabi you should arrive at Hat Yai around 3 pm since the last minibuses for Penang leave between 4 - 5 pm. The Buses for KL leave between 7 - 10pm again from a different place. Take the last bus otherwise you arrive around 4 am in KL and that's to early.

You can drive, walk or catch a regular taxi or motorcycle taxi travel between the Bukit Kayu Hitam checkpoint and Dannok.
