Heilhornet is one of the most iconic mountains at Helgeland- reaching 1058 m.a.s.l. The summit is accessible in a popular, but demanding hike from the parking lot along the road south of Heilhornet. From the top there is an extraordinary view over the coast, and clear day one can see all the way to Træna.

The Heilhornet granite stands high above the surrounding meta-sedimentary rocks, forming three prominent peaks (Heilhornet, Kula and Lesshornet) that are shaped like three sharkfins. This is a fairly common feature in glacially eroded granite terrains. The glaciers eroded on both sides of the peak, leaving a steeper and narrower “nunatak” for each glacial period.

The Heilhornet Pluton is a biotite hornblende graniteintrusion, of about 50 km2 within the Helgeland Nappe Complex. It has been dated to 444 million years and was emplaced prior to the final collision between the Laurentia and Baltica continents, resulting in the Caledonian mountain chain.
