Here's my list.
In the state of Kedah I'd like to experience the Tree Top Walk at Sungai Sedim and get to view the unique flora and fauna of the rain forest walking fifty meters above the ground.

Onward to Pulau Redang in the state of Terengganu. It will be a first for me to snorkel in the clear waters and view the coral, sea anemones and fish. Walk on the pristine white beaches, catch up on my reading and probably sample some sea food. What more could one ask for in paradise? Maybe I'll be inspired to pick up my paint brush and make a watercolour or two.
Third on my list is the Sarawak Cultural Village also known as the Living Museum in the state of Sarawak. Of particular interest is the Pua Kumbu which is a resist dyed fabric woven on backstrap looms.It would be a pleasure to interact with the skilled craftspeople in residence at the cultural village.
Melaka is fourth on my list. Jonker Walk and the Melaka River cruise promise to be informative and culturally enriching. I'd like to try the unique cuisine of the Straits Chinese.
Experiencing Malaysia would be incomplete without exploring Kuala Lumpur. I'd like to take in a show at the Istana Budaya which has a distinctive building inspired by sirih junjung a traditional arrangement of betel leaves used in Malay weddings and welcoming ceremonies.
The Royal Selangor Visitor Centre , BBKLCC and the 'pasar malam' at Jalan Tuanku Abdul Rahman for some retail therapy and street food would round off the five experiences perfectly.
