Afternoon: Meet the transfer at Zaragoza airport or train station and make the 1hr 45 min drive to our hotel. Once settled we'll get everyone together for a full trip briefing; routes, what to expect, and a chance to ask questions before the week kicks off.

Evening: Dinner at a local village restaurant. Good food, good company, early night. The mountains start tomorrow.

Morning: First day on the trail and we're heading across the border to the French side of the range to hike a circular route beneath the iconic rocky face of Pic du Midi d'Ossau. The path crosses a boulderfield with steeper sections of ascent and descent. 

Afternoon: From the high col, there's an optional 40-minute push to the summit - worth it if you're feeling good. The return route passes a coffee hut for a break and caffeine boost. 

Evening: Back to the hotel to sort out your kit for the next few days of hut-to-hut, before dinner at a local restaurant.

Morning: A 20-minute drive to the La Sarra trailhead, then straight onto the trail. The path climbs steeply through pine forest before breaking out into open alpine meadow. You'll pass the lake of Ibonciecho on the way to the Collado de Musales.

Afternoon: From the col, there's an optional scramble to the summit of Musales - a sharp, pointed top with views in every direction. The descent is steep with a short section where you'll need to scramble, before easing down to the Embalse de Respomuso and around to the refugio. 

Evening: Dinner at the refugio, then bed down for the night in your dorm room.

Morning: Today follows a stretch of the famous GR11 - the trail that crosses the entire Pyrenean range from the Atlantic to the Mediterranean. The route follows a climb to one of the highest cols on the whole trail. The final section is steep and loose with a fixed chain to help you up.

Afternoon: From the col, there's a potential 40-minute summit push to Tebbaray (2,866m) for views across the marble peaks of the Picos del Infierno. Back at the col, the route continues down a long descent past vivid blue mountain lakes to our second mountain hut.

Evening: Dinner at the refugio, a last night’s kip in the dorm room.

Morning: The final day on the trail. The route from the refugio takes you past a series of mountain lakes - a strong finish to the hut-to-hut section.

Afternoon: Descend to the finish point for the transfer back to Biescas. Back to the hotel, sauna, swim, relax.

Evening: Celebratory dinner at a village restaurant. It’s your last night, make it count.

Morning: Breakfast, then transfer back to Zaragoza airport or station. Get your last photos and make plans for your next trip!
