The Thin Strip of Sky is a small rift which sits in the southern canyon and stretches south. Its entrance is located in a relatively wide valley. Streams flow along this rift and form a pond at its entrance.

Along the passage, which is constructed around the pond, tourists can visit the deep point of the Thin Strip of Sky. Since the rift is very narrow, tourists can only see a pillar of light when they look up. The Patio, which is not far from the rift, enjoys a spacious area, so that tourists are available to see a rectangular-shaped sky when they raise their heads.

   While walking along the stream underneath the passage, tourists can see several ponds with the Heilong Pond being the largest.

Based in the center of the canyon, the cylindrical peak named Tianwang Tower is a single peak which is not connected with cliffs around it. The former site of the historical Wanping Anti-Japanese Government is about eight kilometers away from the canyon entrance.
