I love my long layovers and I fully take advantage of them for a day of exploration! Luckily there was a great little capsule hotel within the airport. There was also some great Malaysian food spots there too. I also found out later on that the airport boasts full showers in the terminals which would have come in handy after a day of hot, humid exploration.
I didn’t quite make it to the Butterfly Park and I totally skipped the KL Tower and the Petronas Towers.
So the “open air” bird park was slightly disappointing as most of the birds really weren’t in the open air. I actually felt really bad for alot of the caged birds as many were from other parts of the world such as Central and South America. It must be a little sad to be so far away from home trapped in a little cage.
