[1] It was named by a British sailor in 1829 after Dynevor Castle in Wales, based on the resemblance of its summit to a fortress.

[1] Its access is quite harsh due to the nature that all roads end about 30 km from it, and the rest of the way must be done either on a 4×4 vehicle, motorcycle, horse or on foot, either way the appropriate track is just by the shore, not through the woods, as they are too dense.

[citation needed] The ascent is initially blocked by Ñirres (Nothofagus antarctica), which makes advance extremely slow.

Following the wooden zone, vast masses of peat moss come across and, the final part is a mix between loosen rocks, snow and ice.

[citation needed] This place is nowadays part of María Consuelo Estancia.
