The rocks are part of the municipality of Rapa.

The climate is wet temperate. The lower rocks are almost devoid of vegetation - although there is some vegetation on the upper slopes and summits. They are important as a seabird rookery. Fish abound in the adjacent waters. The rocks emerge from a submarine platform 100 meters deep and 5 km in diameter. They lie at a distance between 1.5 and 3 km from one another. The total land area is 43,100 m², which is broken down as follows by the individual rocks:
