Did the Garmo - Algas - Algas N - Argualas circuit from Casa de Piedras, not including Pondiellas though. In fine weather, with Alf in 2005.
Impressive route with 5 3000s.
From the Aguja de Pondiellos the scramble to Garmo Negro looks very difficult, but really isnt so difficult at is looks from Aguja de Pondiellos. From Algas we first go up to the summit that isnt in the 3000 list of Algas SE and then to Argualas (without going all the time by the crest) Cloudy weather in the first part of the route, then sunny.
