The Wind Cave's main features include stalagmites, stalactites and pillars which form when these two join together. Other features include conical cavities separated by blade-like pinnacles of limestone pendants hanging from the roof of the cave passage and current scallops which have a honeycomb appearance and indicate the direction of the water flow.

Squirrels, shrews and a variety of birds can be found along the river and the limestone hill. Black nest swiftlets can be seen and heard inside the cave, as well as 14 species of bat. Twelve distinct species of snail have also evolved in the caves and the covering hill, each unique to its own limestone habitat.

The Wind Cave has been gazetted as a nature reserve not just to protect the cave and it's inhabitants but also to conserve a number or rare species in the surrounding limestone forest. A 1000 metre plankwalk runs throughout the lenght of the cave, so it easy and safe to explore, although the interior of the cave is unlit and therefore a flashlight is essential. A small stream meanders through the cave and joins the Sungai Sarawak kanan at the northern end.
