Launched together with Sentosa's new cable car line earlier this week, the 11-storey (181 meters) Skywalk trail provides visitors a scenic trek among the treetops en route to Fort Siloso. Both the Skywalk and Fort Siloso are free for all, and there are also guided tours at Fort Siloso for a more detailed historical account of the area. Even if you're not a history buff, you'll probably still get a thrill being way above ground.

And while you're there, check out these cool attractions too.
