The Daqikong (Big Seven Holes) Scenic Area covers a different set of karst features from the Xiaoqikong zone: Tianzhong Cave, a large cavern through which the river flows, with boat tours operating through the interior; Bilu Lake, a natural reservoir of turquoise water; and a set of Buyi minority village sites at the edge of the scenic zone.
The cave tour is the main draw — flat-bottomed boats navigate through several hundred metres of underground river passage, with the rock formations lit from the boat. The scale of the cave is evident from the boat: the river channel narrows and widens through chambers of different heights, and the passage where the water disappears beneath a low rock ceiling requires passengers to lie flat in the boat. The exit emerges at the base of a cliff into open river.
Bilu Lake has the same impossibly clear turquoise quality as the Xiaoqikong pools, concentrated into a larger surface area that allows the colour to read from a distance as a vivid panel of blue-green in the surrounding forest. A floating boardwalk crosses a section of the lake near its outlet.
A shuttle bus connects Daqikong to the Xiaoqikong entrance, about 20 minutes. Most visitors do both zones in a long day, starting early at Xiaoqikong and reaching Daqikong by early afternoon.
