Aek Nauli offers a unique trekking experience. The trekkers will reach Lake Toba (east shore) after spending 1 hour of medium trekking (up to 2 hours on a lighter path) from the park gate. Its camping and outbound training areas are quiet except for the sound of birds singing and waterfalls. There is also a passing lane to see the birds, the honey bee cultivation, and the tapping of incense sap and pine resin. Visitors can practice tapping on some trees.
What to Expect
There are many locations to enjoy at the park, but try not to miss the trekking. Four climbs are quite sharp, but the rest should be easy. Even if it rains, the terrain is not quickly muddy. Also, enjoy the waterfall. Not far from the waterfall you will find rivers that look reddish as the water is rusty yet not smelly. The water color is red because its pH level is quite high. Uniquely enough, it does not taste sour.
Once you have reached the shore, there are two ways to go back. First, you may go down from the same road. Second, take a detour, but your exit won’t be from the forest gate.
Entrance fee is Rp 1,500 ($0.13) per person and Rp 150,000 ($13.00) per car.
