Menez Hom is the first small Armorican mountain facing the ocean. It is the most westerly peak of the Black Mountains.

Culminating at a modest altitude of 330 metres a.s.l, it is however a real balcony over a largely clear scenery towards the Brest Bay, Crozon Peninsula and Douarnenez Bay.

It reveals an exceptional natural heritage recognized under Natura 2000. It largely reflects the local geology with the Armorican Sandstone that has resulted in the development of Atlantic short moorlands that are home to heather.The site is easily accessible, and it is possible to deepen the visit thanks to the many available footpaths. A pilot study for an interpretive path, based on an ancient sea level, located 210 metres a.s.l, is currently under evaluation thanks to a project leaded by Geological and Mineralogical Society of Brittany
