What would you like to do Sabah?
1.Climb Mt Kinabalu (minimum 2 D 1 N).
2. See the orang utans in Sandakan at the orang utan sanctuary (2 feedings..1 in the morning, 1 after lunch)
3. River rafting on the raging padas river
4. A day spent in downtown Kota Kinabalu at the local markets and bazaars and maybe half a day at Manukan Island if you are into the beach stuff.
5. The cultural show in Inanam in Kota Kinabalu (2 hours max I think) is def well worth going to
6. Miki's jungle camp (if you like jungle trekking and spending a night in a jungle below mt kinabalu and visiting a real local village)
There's lots to see and do in Sabah. It just depends what takes your fancy.
You need to hire a guide for safety reasons. It isn't a case of is it a technical climb or not. Its a simple case of safety.
And you are also generating incomes for the local villagers in the area.
You need to book well in advance if you want to climb mount kinabalu and ensure you have accomodations at laban rata via sutera sanctuary lodges or via ferratta.
I am serious about booking in advance as the mountain generally sells out 3-4 months ahead.
You can't do day climbs anymore as this was stopped in Aug 2014.
