Asian Mountains, Bali
Gunung Abang/ Mount Abang, 2155m
Gunung Abang is the 3rd highest mountain on Bali and is located on the southeast side of Batur Lake and 10.6km northwest of Gunung Agung - the highest point on the island. Hikers who come to Bali do not normally consider this mountain unless they're after top 3's or mountains with a high primary factor.
There are two routes to the summit but the route up the southwest ridge is the normal one. If you don't know the area, hire a guide. Once on the forest path the onward route is obvious, but it is locating the trailhead that is the challenge. There are two temples for praying on the southwest route and one more temple on top. The mountain is mostly visited by locals.
The hike is fairly easy - 760 vertical meters and 3,1km to the top on a forest path.
Abang (2155m, UTM 50 L 327042 9084376) has a primary factor of 905m towards the higher parent mountain Gunung Batukaru (2276m). The defining saddle (approx. 50 L 307270 9091394) is found northwest of Belatih. Ref. Google Maps, the saddle is within the range 1240-1260m, interpolated to 1250m.

Route 1: Kedisan - Mt. Abang
The route starts at Kedisan, on the south side of Batur Lake. If you come from the south side of Bali - somewhere near Denpasar, it will take you a couple of hours to get there by car.
Follow road Jalan Kayu Ambua to the east/west junction (S8.28423 E115.36505) at Kedisan and turn right (east) (if you drive Raya Penlocan 0,35km to the west, you reach the Batur Lake junction).
Follow the road to the east for 2,4km to the Abang trailhead (S8.28604 E115.40749 - not marked). Parts of this road is seriously bad. Hopefully, you have a driver. You should not consider driving this road with a rental car.
The 3km forest path runs straight up the forest without any notable forks. You pass two temples (S8.28567 E115.41969 and S8.28396 E115.42361) on your way up the forest and there is also a temple on the summit (S8.28027 E115.42960)
