The big attraction of Permai Rainforest Resort in Kuching, Sarawak is that they have a few tree houses for lodging. That's quite cool! Unfortunately, they were fully-booked when I was there. We ended up staying in single level cabin which was also nice. The resort is located at the foot of Mount Santubong. So there is a fair chance you will encountered wildlife. We spotted Silver-leaf Langurs and Colugos during our stay. We arranged for a day trip to Bako National Park.
Here's a photography account of the trip.
