The rock, with height of about 8 meters, has an abrasion cave that is 4.5 meters high and about 10 meters long. The cave's upper part is 3-4 meters wide.

It borders sea to the east and a low hill to the west.

There is a low sea cliff in its north side, and round basaltic rocks lie below the cliff.

Pines and maples grow on the west low hill to add beauty to the rainbow-shaped rock.

The rock with an abrasion cave is of significance in coastal topographical study.
