TOURIST INFO: LRT: KLCC. Open Tuesdays-Sundays 9:00am - 5:00pm (except for Friday from 1:00 - 2:30pm) even on Public Holidays (see exceptions below). Mondays are closed except for Public Holidays and School Holidays (half day 9:00am - noon sessions). Basically if you want to go on a Monday, call ahead to check. The Skybridge is also closed for multiple days around Eid Al-Fitri (end of Ramadhan) and for the day of Eid Al-Adha. These dates change every year so make sure you look up the info before going!

The good news is it's FREE. The bad news is there're only 1,300 timed tickets a day and it's given out on a first-come, first-served basis. Also, after having waited all that time for a free ticket, you only get to ascend to the 41st floor (170m) and you can only stay inside for 10 minutes. If you are visiting the Petronas Twin Tower Skybridge during a weekend, you will probably need to stand in line 30-60 minutes before they start giving out tickets. They start giving out tickets at 8:30am and the first tickets are for a 9am visit. The lines can be very long (up to 2 hours queue) during the weekends (on one visit, it snaked out the doors of the Towers and around the central court area). Weekday mornings are fine. You can walk right up to the counter and get timed tickets for an hour later, no problem. Don't quote me on that though especially if a public holiday falls on a weekday.

TIP: If the lines are just way too long and you don't have many days in KL, go to the KL Tower instead. It has far better views (personal opinion) and it hardly gets overly crowded even on weekends. It's not free though (RM8 per adult) and it's harder to get to (the LRT doesn't go there). In my opinion, the only novelty in visiting the Skybridge is the coolness of being in a bridge suspended 170m above the city. The views are obstructed, and not as grandiose and all-around as the views from the KL Tower. Still it is rather cool and you should do it at least once.
