The "Best of Putrajaya Tour" is a new initiative of the Putrajaya local government.
Pay 1 RM and you can embark in a 2-hour English-guided sightseeing tour around Putrajaya where you'll be shown its landmarks, interest points, and be told its tales, facts, etc. There will be photostops and half an hour rest to taste the local foods.
Schedule: Sat and Sun (weekends only), every 11 am AND 3 pm
Fee: 1 RM (ONE Malaysian ringgit, that's 30 cent in USD!) per person, paid on bus
Booking: Easiest way is to sign up on-the-spot, at Putrajaya Sentral station until 30 minutes before departure. Look for the "Best of Putrajaya Tour" booth and sign yourself up. There is a quota of 40 people per session (it is the max seating capacity of the tour bus).
How to get there: Easiest way is by KLIA transit train from the KL Sentral station. You'll reach Putrajaya in around 20 minutes.
I experienced it today and it was awesome, I mean, what can you get nowadays with 1 RM? FYI, in Putrajaya hourly taxi rental will cost you 30 RM/hr.
