It's a MUST DO!
What was the most inspirational moment of your trip?
I really found it very hard to find a single moment which would fulfil this description. There were just too many great moments.
What did you think of your group leader?
Alvaro is a great guide. Attentive and knowledgeable of this area which he clearly loves dearly.
Do you have any advice for potential travellers?
Fitness is an absolute must. These are steep hills do not enter them lightly. There are big climbs and big descents and if the heat is up they can be punishing. Bring a good camera! Bring field glasses.
Is there anything else you would like to add?
If you love walking, you'll love the Picos.
