The Kuala Lumpur Butterfly Park is located in the Lake Gardens area which includes the KL Bird Park, National Mosque of Malaysia, Islamic Arts Museum, etc..
I like butterfly parks so I enjoyed it. It was an impressive butterfly park but it is also pretty much what you expect if you have visited several. If you enjoy them then I think it is well worth a visit. If you don’t know, it is a good one to check out and see if you like them.
A big part of what I enjoy is the photography so if you enjoy photography you may well also enjoy a visit.
