Day 10 of GR5 Hike: Into Samoens through the Gorges along the Giffre

 These dry gorges in limestone cliffs are remnants of glacial torrents.
Alan can be seen for scale above; the metal ladder in the photo below.

 Samoens has a botanical garden, photo above and a nice hostel "Gite les Moulins" run by Mireille, below.  The flowers above are Eryngium alpinum and Elecampane/Inula.
