This volcano is supposedly the most active in Indonesia. It is the highest point of Siau island in the Sangihe Islands off the north coast of mainland Sulawesi. It has five summit craters and a north peak and a slightly higher south peak. Trying to climb to the top is probably asking for a lot of trouble! However, a wander round the island is well worth it in order to have a look at the devastation caused by previous eruptions. Siau is also a particularly beautiful place with some excellent beaches.
There are apparently three routes – Kampung Dompase (at 558m) where you can also visit the Vulcanology Post to see the monitors, look through books and ask for information, Lintatua (‘old worm!’?) which is not far from the main town of Ulu, and the more northerly approach from Dame. Dame is recommended for good photos at sunrise but climbing from Dompase which takes 25 minutes to reach by motorbike from Ulu is very straightfoward. In less than half an hour of hiking from the end of the cement track at Dompase you will have reached the start of the lava flows and bare rock leading to the summit. At night you can often see the orange glow of lava and hear volcanic explosions.
- Getting there: There are boats from Manado (or Tahuna) several times a week. The fastest is the Prima Oasis which takes about 4 hours from Manado and 2 hours from Tahuna (which has a small airport).
- Accommodation: A few hotels in Ulu – notably the Hotel Jakarta which is pleasant, clean but prices don’t include breakfast.
- Permits: Not required, but it is probably a good idea to check with staff at the Vulcanology Post in Dompase with regard to the status of the volcano.
- Water sources: Unknown – take plenty with you.
- Travel insurance: We recommend World Nomads insurance, which is designed for adventurous travellers with cover for overseas medical, evacuation, baggage and a range of adventure sports and activities including mountain hiking.
