We are staying in Kota Kinabalu the end of next month. There are 4 adults. Looking at booking a flight from KK to Sandakan to go to Sepilok Orangutan Sanctuary and then Labuk Bay Proboscis Sanctuary. Finding it hard to get info on transport airport/Sepilok/Labuk (or even swapping round Sepilok and Labuk. The best I can find is complete day tours but they are expensive and we are quite happy in organising ourselves rather than have the restrictions of a day trip. Any advice would be greatly appreciated.
