June 13, 2026,Port du Castet Mtb exploration

Super nice day in the mountains, mostly on Mtb routes 8 and 10. Guard dogs and lots of other farm animals encountered. With @Helo Coastie

June 14, 2024,Vallée d'Ossau - Circuit 10 (rouge) Tour du Séserite

A long climb on the track then time for freedom in the summer pastures. Cow trails with stunning wild scenery. No technical difficulty, a little physical with some pushing. The herds are in place for the summer. A little less than 2 hours to do the tour without counting breaks
