The Wind Cave Nature Reserve is part of the Bau Formation, a narrow belt of limestone covering about 150 square kilometres of Southwest Sarawak. Due to the comparatively soft and soluble nature of limestone, and the intense tropical rainfall of the region, the whole of the Bau Formation is intersected with caves. The Wind Cave Nature Reserve covers 6.16 hectares which includes the cave itself and the surrounding forest.

The Fairy Cave is the largest cave entrance in the Kuching area and is a few minutes away from Wind Cave by coach. Access requires a bit of exertion, and visitors should expect a climb using concrete steps rising about 100 feet with a further set of wooden steps to the main chamber. The roof of the chamber towers above you as you enter through a small side passage. This enormous space was carved out from the rock through water activity with the stalactites, stalagmites and columns which adorn the chamber formed subsequently.

Semenggoh Nature Reserve is by far the biggest Orangutan Rehabilitation Centre in Sarawak. Back in 1975, it was established as a sanctuary for Orangutans who were injured, orphaned, or being held captive as illegal pets. Currently, the centre serves as a habitat for the Orangutans and also a place for visitors to learn about this endangered rare species. This wildlife centre has a thriving population of healthy adolescent and young adult semi-wild Orangutans. Semenggoh Nature Reserve is also a habitat for rare flora and fauna, including the giant squirrel, pigmy squirrel, and a variety of birds, making the nature reserve an ideal place for nature lovers.
