Sitiawan is a small town and most attractions are relatively close together. A rental car is the most practical option for getting around, especially if you plan day trips to the coast or nearby towns. AVIS operates from the airport.
Taxis are available around town and are convenient for shorter trips. Fares vary, so agree on a price before you set off. The Star Shuttle bus connects Sitiawan to Kuala Lumpur but is not practical for getting around within town.
