Sepang  is a district in the Malaysian state of Selangor. It is located 50 km south of Kuala Lumpur. Most visitors head to Sepang to get to the Kuala Lumpur International Airport (KLIA) and Sepang Formula One circuit are located within the district.
The district centre is Bandar Baru Salak Tinggi.
Sepang is also the name of a small town on Federal Route 5 or the main West Coast road where there are local bus connections to Port Dickson in Negeri Sembilan, KLIA, and Banting further north on the Selangor coast.
Until 2000, Sepang district was just a flat stretch of palm oil plantations. Now it has tens of millions of visitors a year because of two reasons: The Sepang Formula One racing circuit, and KLIA.
However, outside these two attractions and the areas bordering Petaling Jaya, you will still be greeted with tranquil villages and miles of palm oil plantations.
As Kuala Lumpur International Airport is in Sepang, visitors can certainly fly from many oversea destinations directly into the district. For information on how to get to or away from the airport, see the "Get in - KLIA" section of the KL article.
The KTM Komuter can also be used to reach Sepang. Catch a train to Nilai station in Negeri Sembilan. From there, Sepang Omnibus goes to locations within Sepang district, including KLIA, Salak Tinggi, Sepang (for connections to Port Dickson in Negeri Sembilan) and Sungai Pelek.
You can also use the various bus connections between Kuala Lumpur and KLIA to reach Sepang - see the "Get in - KLIA" section of the KL article for details.
Transnasional  has a bus service from Kuala Lumpur's Puduraya bus terminal to Salak Tinggi, Sepang and Sungai Pelek. Transnasional also operates local buses from Sepang and Sungai Pelek to Tanjung Sepat and Banting in neighbouring Kuala Langat district. This journey passes through miles of palm oil plantations and several pretty Malay coastal villages.
Sepang Omnibus has direct local buses from Seremban in Negeri Sembilan to Sungai Pelek via Nilai, KLIA, Salak Tinggi and Sepang; and Seremban to Banting via Nilai, KLIA, Salak Tinggi and Bukit Changgang. It also runs a bus from Sungai Pelek to Port Dickson in Negeri Sembilan via Sepang. Towards the north, Sepang Omnibus operates buses from Sungai Pelek to Tanjung Sepat in neighbouring Kuala Langat district.
Except from KLIA, local taxis operate from the main towns of the district. From KLIA, a coupon airport taxi system operates. See the "Get in - KLIA" section of the KL article for details.
To Sepang International Circuit
During race season, the simplest way is to catch the train from KL Sentral to KLIA and then transfer onto shuttle buses which will bring you to the circuit. The operator of KLA Ekspres and KLIA Transit has transport packages which cover the train ride and shuttle bus. See the KLIA Ekspres website  or Sepang International Circuit website .
On non-race days, it may be difficult to get to the circuit by public transport. Your best bet is by taxi.
Public transport within Sepang is limited to the Sepang Omnibus, which connects KTM Komuter's Nilai station to the airport via the Sepang International Circuit race-track (RM 2, every 30 minutes).
Hotels and, when races are on, the F1 circuit run shuttle buses to ferry visitors to and from the airport.
