Most of Kuala Lumpur's historic sights are located in and around the Merdeka Square/Jalan Hishamuddin area, while many of the gardens, parks, and museums are out at Lake Gardens. Taxi fare between the two locations should run you about RM5 ($1.40/70p).
City tours can be booked through Tour Fifty-one, located at the MTC (Malaysia Tourism Centre) on Jalan Ampang (tel. 03/2161-8830). They coordinate a half-day coach tour for RM50 ($14/£7) adults and RM30 ($8.40/£4.20) children. It swings by most of the places listed here but is rushed.
