Selangor is the wealthiest, most urbanized and, with 4.1 million people, the most populous of Malaysia's states. It is centred around the urban sprawl of the Klang Valley, surrounding but not including the capital Kuala Lumpur and the federal administrative capital Putrajaya.
Malay is the national language of Malaysia, but the use of English is widespread. Most locals are bilingual in Malay and English, and many understand other languages such as Tamil, Mandarin and Cantonese thanks to Selangor's racial diversity.
The new Terminal Bersepadu Selatan, (TBS-BTS) or Integrated Bus Terminal at Bandar Tasik Selatan serves all southbound buses, taking over from Pudu Raya in Kuala Lumpur. The terminal is located next to the Express Rail Link (ERL) KLIA Transit Station, the Stesen Komuter KTM Bandar Tasik Selatan and the Bandar Tasik Selatan LRT Station (Star LRT). There are also Rapid city buses and a taxi rank. The cheapest way to get into the city is to use the Komuter train.
Selangor is a reasonably safe state. However, several cases of snatch thefts have been reported in urban areas, some including deaths, so be careful with your belongings. Make sure to put handbags away from open car windows and where motorbikes can easily snatch your handbags on roadsides, and try to have at least one companion to accompany you around, even if you are a man, as criminal cases have been on increase of late.
