Download the GO KL app immediately - these completely free buses cover every major tourist spot and run more frequently than most cities' paid transport. Seven color-coded routes connect KLCC (Petronas Towers area), Bukit Bintang (shopping district), Chinatown, and KL Sentral (main station).

Key Routes: Green Line runs direct between KLCC and Bukit Bintang every 5 minutes during peak hours. Blue Line circuits through heritage Chinatown and Central Market. Purple Line connects Pasar Seni LRT station to Bukit Bintang shopping. Red Line hits KL Sentral to city center.

Schedule & Tips: Weekdays 6am-11pm, weekends 7am-11pm. Buses are clean, air-conditioned, and have dedicated space for luggage/strollers. Each route intersects at major hubs so transfers are seamless. Real-time GPS tracking shows exact arrival times.

I've saved RM200+ per week using these instead of RM15-20 rides for short hops within the free zone. The Purple Line even connects to KL Sentral for the KLIA Express airport train. Regular city buses offer good value for longer routes outside the tourist areas, but within the city center, these free routes can't be beat.
