This 12 km (7.5 mi) walk across central Kuala Lumpur covers some of the main sights in the city centre.
Understand
This is a very diverse hike, during which you can experience the most bustling parts of the city as well as rain forest stretches that you will most likely have all for yourself. By no means should this be your only walk in the city. The Titiwangsa Lake Gardens and the Botanical Garden with all its sights should be on your list as well.
Prepare
About the only equipment you will need is comfy shoes, sun screen and possibly insect repellent. There are countless restaurants, food stalls and mini markets along the way. Some top picks are highlighted. The hike will take you around 3 hours of pure walking. With museum and sightseeing stops - especially at KL Tower - plan at least 5 hours for the whole trip. It is best to take this walk early in the morning or in the late afternoon, in order to avoid the hottest hours of the day.
One option could be to start the walk at around 16:00-17:00 at Maharajalela station to arrive at the observation deck of KL Tower shortly before sunset (19:15-19:30). The attractions in the second part of the hike (namely Changkat Bukit Bintang, Pavillion, KLCC Park, Petronas Towers and Saloma Link Bridge) are all even more impressive in the dark. Chow Kit market will already be closed at this time though.
Get in
The sightseeing walk can be accessed at numerous points. If you are planning to walk the whole distance it is advisable to take the Monorail to either 1 Maharajalela 
(southern end) or 2 Chow Kit (northern end).
Walk
Chinatown
Exit Maharajalela monorail station and walk towards northwest. You will reach Chinatown and the colonial district.
