The trip from Parapat to Muara Nauli takes about 3 hours. The road is narrow. So the big bus can't pass by this road. There is a small airport, Silangit Airport, which located not far from Muara Nauli. It takes about a half hour by flight from Polonia Airport to Silangit Airport. Of course the trip is faster by air than by land.
The fatigue during the long trip by minivan went away when we see the beautiful scenery along the road. In Muara Nauli, the scenery is more amazing. The nature and the air were still natural, fresh and beautiful. In Muara Nauli, there is a hotel. named Sentosa Lake Resort. It is a new hotel, the room is big and clean, the staff is very friendly and behind this hotel is Toba Lake. So, you can swim in here, the Lake was clean and the water is transparent and cool in the morning.
