We (family with 3 older kids of 18, 16, 14 years) are planning to spend 4 nights in Borneo next August. Our main interest is nature and wildlife. I was thinking of going up the Rejang river to Sibu and maybe further. Does that make sense at all given our time limitations? Or would we be better off just going to Bako and the Orang Utan sanctuary? Or should we consider going to Kota Kinabalu rather than Kuching?
I would be grateful for any advice.
