A walk northwards along the road eventually reaches Olavatnet. Here lies the contact between the conglomerates in the south and the oceanic crust in the north. As we continue northwards through these beautiful surroundings, we see that the oceanic crust mainly alternates between thick sequences of lava flows and pillow lava. Large, fine pillow-lava formations can be observed along the whole route.
You may also choose to follow the much-used trail from Ytrøyna southwards to Sperrefjellet. Here, the walk begins in the oceanic crust with many fine pillow-lava formations, before continuing southwards into the conglomerate on Sperrefjellet.
