Gunung Ambang is an excellent volcanic crater complex and one of the easiest hikes in Sulawesi, requiring just under 2 hours to reach the crater from the trailhead. It is well-known for its bird life – you stand a very good chance of spotting eagles if you stay in the area for a couple of hours. Alas, it would appear that the highest point is in dense jungle with no trail to it, but if you know otherwise please let us know. The best starting point for Gunung Ambang is Desa Bongkudai Baru which is about 30 minutes by car from the small city of Kotamobagu.
Bongkudai Baru is well over 1,000 metres above sea level and on the shores of the picturesque Danau (lake) Mooat. The views over the lake at first light are exceedingly pleasant. The trail leads up a wide farm track between fields in which farm workers will probably be working even at 6am. Before long the trail narrows and enters forest. At this point there are several important and unsignposted turnings you need to make so a local guide is essential. The track is pretty muddy in places but after less than an hour you enter an area of elephant grass. Before long you will see the crater cliff walls and smell the faint whiff of sulphur in the air.
After a junction (left for a camping area and a stream of natural hot water which is reportedly safe to drink) you find yourself on white rocks at the start of the crater itself (1,450m). The view back down to Danau Mooat and a jungle-clad peak behind it is wonderful but the better views are actually to be found further over on a little rocky top on the far side of the crater area. A few fumaroles seem to be permanently active. Up to the right are steep crater cliff walls. An orange flag marks the point where local hikers managed to reach after negotiating the difficult and potentially dangerous terrain.
Unfortunately the highest peak does not appear to be visited due to the density of bush up there but you can climb part of the way up the crater wall for an excellent panorama of the entire crater area. Back down near where the camping spot is you should be able to make out a weird mini-crater with a muddy cone but apparently this too cannot be accessed without the use of a machete.
It is best to leave yourself at least two hours to enjoy exploring the scenery and taking photographs of the fantastic landscape. A descent back to the trailhead takes little over one hour where hopefully you will have transport waiting to take you back into Kotamobagu.
Gunung Ambang is well-known in the local area, but due to its relatively obscure location is not as famous nationally as it ought to be. A recommended hike, even for beginners.

|Getting there||Kotamobagu is 3-4 hours by car from Manado and 5-6 hours from Gorontalo. Daily buses run but they generally seem to leave in the early morning only.|
|Accommodation||There used to be accommodation on the shore of Danau Mooat but it has since closed. Several hotels in Kotamobagu including Plaza Hotel which is good value but the rear rooms are dangerously close to loud all-night karaoke.|
|Water sources||Natural hot water available at the camping area near the crater.|
