If you are coming from Kuala Lumpur, Merapoh is fairly straight forward to reach. There are three mode of transportations. Car is preferable because you will have the chance to stop and enjoy the road trip. Bus would be nice too because it is cheaper. Train is an alternative because train to Merapoh came in once a day at night.
Here is the direction from Kuala Lumpur to Merapoh:
Merapoh is a very small village. One thing to know if you are getting closer to Merapoh is when you are out from the highway which is still under construction. In the future, there will be an exit straight to Merapoh so the travel time is faster. You will see the train station at the left side of the road and small terrace of shops on the right. The shops are built at the junction to Taman Negara. So, it is quite an easy landmark if you want to head to Taman Negara.
There are many agencies in the shoplot but it is preferable to contact and make a booking with them before travelling to Merapoh. If you arrive at night, it will be quite difficult for you to find a place to stay a night. One possibility is for you to sleep at the station but safety is not guaranteed. If you do need a contact, please contact Ra Adventure Travel and Tours at +60179153034 or contact Rosni directly at +601125516025.
Until then, have a good adventure to Merapoh.
