This hiking site and viewpoint displays the mantle section of the Leka Ophiolite, metaharzburgite. The harzburgite is the most common rock from the mantle section, and its typically weathered chocolate-colored knobbed surface is easily observed at Lauvhatten due to little vegetation. Parallel structure and planar foliation is seen in the bedrock at several places, structures formed during ductile flow in the mantle beneath the moving, crustal plates. Pockets of yellow dunite are found sporadically, reflecting patches of partial melting in the mantle rocks.

Bunkers and remains from WW II are found at the top of Nordlauvhatten, protected as a cultural heritage site. The top is a viewpoint, with a particularly good view towards Lekafjorden, Skeisnesset, the mainland and the northern coast.
