Borneo – September 2025

I have just returned from a 2 week Naturetrek Trip to Borneo. We had 1 night in Sepilok, 7 nights at Deramakot and 3 nights in Kinabatangan. This was my first time in Borneo so a lot of the mammals seen were new to me.

At our night in Sepilok we saw Philippian Slow Loris, Western Tarsier, Prevost Squirrel and Common Giant Flying Squirrel.

The next 7 nights were spent in Deramakot where we had hoped to get a good view of a clouded leopard. Spoiler, we did not see one!

However we did see an array of other mammals including Pig-tailed macaques, a total of 20 different Bornean Orangutans, Leopard cats, 5 Colugo, Palm Civet, Malay Civet, Banded Civet, Small-toothed Civet, Sambar Deer, Northern Grey Gibbon, Lesser Mousedeer, 2 Marbled Cats, Red Langur, Silver Langur, Flat Headed Cat, Binturong, Thomas’s Flying Squirrel, Plantain Squirrel and Giant Flying Fox.

After the 7 nights at Deramakot we moved to Kinabatangan Wetlands where we saw Pygmy Elephants, 10 group of Proboscis Monkeys and Long Tailed Macaques.

This was an incredible trip where I saw 30 new species of mammals and I guess I will have to return to see that elusive Clouded Leopard.

    2 Marbled Cats!! Nice. They are harder to see than Clouded Leopard. Very envious.

    Cool list of species! Sabah is something special. Did you have Henri Sappingi, a.k.a. Mr. Marbled cat guiding you? He seems to have a magnet with them.
