Tangkoko-Duasudara Nature Reserve (8890 ha) sits like a thumbnail on the northern east tip of the peninsula. This Reserve is one of the most beautiful rain forests in Indonesia .
The Reserve contains 3 volcanoes:
-Mt Tangkoko (1109 m).
-The ash cone of Batuangus (450 m) which resulted from an eruption in 1893.
-And the twin peaks of Duasudara (1351 m).
The Tangkoko-Duasudara has been famous the time of Wallace, a British naturalist who visited Sulawesi in the 1850 s,for its abundant and unusual wildlife (e.g.,Maleo bird).In 1919 the Dutch colonial government declared Tangkoko a Nature monument. In 1942, the Nature protection ordinance established Tangkoko as a Nature Reserve. After independence the Reserve was retained as a Nature Reserve and responsibility fell under the Ministry of Forestry.
Tangkoko Wildlife 
The photos in your gallery are amazing! I had never heard of Sulawesi, so I had to google it. Now I want to visit so bad! It won’t be happening any time soon, unfortunately, but I’m putting this on my bucket list.
Hi Sir,
thanks to visit my blog. anytime, if you need some more info about Sulawesi and surrounding, just send me email to ask.
best regards

Hello Iwan,
I am looking at logistics for a wildlife tour with a small group (10-12) from the US to Tangkoko Nature Reserve in May or June of 2025. We will be interested in observing and photographing the wildlife. I have read some nice reviews of your work there and would be interested in adding you on as our guide. If you are unavailable but have other recommendations, please let me know.
Best regards,
Jeb
Fantastic trip in Tangkoko last week with Irawan!
Very nice guide. I enjoyed every minute. Really it’s a lifetime experience. Highly recommended to take tour with Irawan in Tangkoko.
Thanks for a memorable day! 😊
Thank you for a great experience for the past 6 days. Saw 95 per cent of the birds. Next year coming back again to Sulawesi for birding and photographing. Hope you can arrange the trip again.
