what about Telemoyo mountain ? In the seventies a telecommunication relay station was built on the top of this 1894 m mountain, and to reach it a 7 km road was carved in its side all to the top. So you can drive there, although the road is narrow and in some places in poor repair.
When the weather is clear, from the top of Telemoyo you have a magnificent view on the surrounding valleys and neighbouring mountains: Mt Merbabu, Mt Ungaran and Mt Andong.
At the start of the road there is a gate, and you have to pay Rp 5,000 for a car. You are warned not to leave your car unattended and to be back not later than 5 pm. If you meet a car from the other direction, you may have to do some backing up, because at several spots the road is too narrow to pass each other. Last time we went there on a Sunday, and the gate of the telecommunication station was closed. That meant also backing down 100 m, to reach a spot where we could turn the car around.
Directions: From Salatiga take the road to Kopeng. At Wates village, where the road turns sharply left, take the road going down on your right, following a sign saying 'Wisata Kali Pancur'. After 3.4 km a road coming from Kopeng joins in at your left. 300 m from this junction, at Pandean village, a sign 'Telemoyo' points right. Here you find the gate of the road up Telemoyo.
