From the intersection of Rachadamri and Rachaprasong Roads, make a right turn and continue walking for about 100 metres (past Amarin Plaza and McDonalds) until you get to an escalator which will take you up to the skywalk. From here you can gawk at the impressive tree in front of the InterContinental Hotel on the other side of the road, before making your way (still on the skywalk) past Gaysorn and down the stairs to CentralWorld Square, where local beer brands have set up beer gardens with nightly live concerts throughout December.
