We woke up to the most condensation yet. Yesterday I pushed hard to go as fast as I could over the easier trail. Today I felt sluggish all day. I just never got into the groove. 

We had a hard climb up to Bocca a e Porte, at an altitude of 2225m (7300ft) but were rewarded with great views.

The next section had a few places with chains which really helped. Other places I just had to be creative with how I could lift myself up or down and over some boulders, slots or cracks.

My turn

We traversed this

The second half of the day was just hard work and I felt like it was a bit of a death march. We finally got to the Bergeries de l’Onda which had camping on flat green grass! The grassy area was enclosed with a fence to keep out the donkeys and sheep. I took a cold shower which revived me. We bought jarred bolonaise sauce and cooked another great dinner. With wine it was just what I needed. 

Space for more tents and more tents did arrive.
