|Taman Negara could be expensive if you go to the resort. Most people book this excursion in advance at their travel agency.
It takes 3 or 4 days to visit Taman Negara.
It can be cheaper, if you're a backpacker or so. There's also a youth hostal between the chalets in the resort.
Right opposite the resort, just across the river, is a little place called "Kuala Tahan". In this little town, which is just outside the National Park "Taman Negara", are some hostels. You can stay there and in the daytime you can visit the Park.
In the evening you can have dinner at one of those lovely floating restaurants in the river. Even some people of the resort come for their dinner to those floating restaurants.
If you like to visit Taman Negara, you need a permit, which will be checked by the police if you cross the river to enter the Park.
But when you book by a tour operator these permits are included.
I put on this page some advertisements, which I found in the local newspaper: the New Strait Times. These advertisement are very profitable. Please contact the Travel Agents and let you inform and ask them about the price of the package deal. These packages seem fair to me.
