This was the longest trip I've ever done. It went really well. A tremendous part of the world, wild, remote, spectacular. Gear performed well and I had a great time. The route I started at Riglos, a small town north of Zaragoza in northern Aragon. The photo above shows the scene that greeted me as I stepped off the train. I finished at Alquezar, a small tourist town in the heart of the Parque Natural de Sierra de Guara where I took a bus back to Barcelona via Barbastro. The first part was largely on the GR1 and the Camino Natural de Hoya de Huesca which run largely on the same route. The second part was on paths around the Mascun and Balced canyons using the town of Rodellar as a base. Route and rough distances Day 1: Barcelona to Riglos by train then walked to just short of Loarre, 15km Day 2: Loarre to just after Bolea, 17km Day 3: Bolea to Meson Nuevo just after Arguis, 19km Day 4: Meson Nuevo to Nocito (campsite), 17km Day 5: Rest day pottering around Barranco de Pillera canyon near Nocito, 9km Day 6: Nocito to Nasarre via Abellada, 26km Day 7: Nasarre to Rodellar campsite and half day rest, 10km Day 8: Circular walk around Mascun canyon, 20km Day 9: Short walk on Mascun canyon floor, 9km Day 10: Rodellar to just before Radiquero, 21km Day 11: Radiquero to Alquezar, walk around canyons near town and travel back to Barcelona, 15km walking The good Going on the train worked very well. Overnight Paris to Perpignan and then a change to Barcelona on the way out and a day train from Barcelona to London via Paris on the way back. Train from Barcelona to Riglos and buses back all were easy and comfortable. First time I used a Strat2. Took a bit of getting used to but performed well. Speedster stove was brilliant for one person meals as was my DIY wood burner. DIY dehydrated food was great, I didn't get the hunger cravings I've had in the past. The route was well signed for the first days and the 1:40K Editorial Alpina map was excellent for the latter part. There are lots of short local paths looping off the GR1 which I really enjoyed as they generally led somewhere wonderful. It was easy to find wild camping spots and water. Most villages had a fountain. I stayed at campsites in Nocito and Rodellar which were fine, very quiet with good facilities. Daytime temperatures were perfect, around 15-20 with hardly a drop of rain. Nights were occasionally below freezing but mostly around 5 I'd guess. Doing some work on my Spanish hiking vocabulary. Don't expect English to be widely spoken by older people. There are loads of French tourists round here in the bigger towns so French is helpful too. Do better next time I panicked and took way too much food and warm clothing. So bag was too heavy which was a literal pain for the first part until I ate most of the food. I noticed my energy levels really dipped in the second part, maybe due to the weight of the bag? Maybe my food wasn't as good as I thought? Viewranger was hopeless. I downloaded maps and routes which I could see but the function to actually locate where you are did not work at all. I checked when I got back to the UK and it seems fine here. Had it worked I had GPX routes and maps downloaded from several sources. Some photos Looking back at Riglos. Typical scenery for the first few days. The path mainly keeps low but most days had around 500-1000m of climbing usually in fairly short stretches. First night's camp in the Strat2. Difficult to cram it into a tight spot in the forest. Fortunately nobody hared up the track in a 4x4 chasing wild boar. Canyon just north of Bolea. A small hermitage is crammed into the folds of the rock. Hermitages and abandoned villages were good bets for a flat spot of ground. Ermita de la Trinidad even provided a table and running water. The route was well signposted. I gather the GR1 is a bit hit and miss in this regard but Aragon seems to be on the ball. There was snow higher up and on northern slopes. But also the flowers that emerge when it melts. I had to abandon a planned section of my walk due to a heavy snow fall in early April. Spring doesn't come early here. I was mostly walking at 900-1200m altitude, dropping down to around 600m in Rodellar. Camp spot at Meson Nuevo near Arguis, an abandoned terraced field. Views were OK. There is a lot of limestone and sandstone here. Often, erosion has created rivers with polished sandstone beds. Lots of dry stuff for woodburners. Note careful placement of stove on rock. The whole thing fell over just after I took this photo, incredibly balanced against a stone. Burner kept going and pan didn't spill a drop. Countless abandoned villages in northern Aragon that fell into disrepair in the 60s and 70s as Spain's economic boom kicked in giving people more job opportunities elsewhere. Campsite at Nocito. Great views but freezing nights as the air falls down the flank of the Tozal de Guara mountain. The tenth beautiful waterfall in half a mile of walking near Abellada. I burst out laughing turning a corner to find yet another one. Another former terraced field in an abandoned village provides a great camp spot with views of the fading evening light over the high Pyrenees to the north. Canyon country. The Mascun near Rodellar where 3 major canyons run parallel to each other. Heaving with climbers and canyoners in summer apparently. Somehow the path didn't look like this on the map... There were numerous bike tracks. Spain. Health and safety. Eroded needles, vultures flying above. Canyon between Rodellar and Alquezar which reminded me of Jabba the Hutt from Star Wars. Final campsite of the trip. Disconcerting to find loads of shotgun shells 50 yards away. More info I found these websites really helpful (some are only in Spanish or maybe Spanish and French) https://turismo.hoyadehuesca.es/la-hoya-de-huesca/natural/camino-natural-de-la-hoya-de-huesca (practical route info and GPX files) http://www.johnhayeswalks.com/2013/04/gr1-sendero-historico-review.html (commentary and route info) http://www.prepyr365.com/es/rutas/senderismo/prepirenaica-trail.html (route alternatives and GPX files) www.rednaturaldearagon.com/senderos/ (look for "Sierra y canones de guara" in the menu, details of many fabulous small local paths off the GR1) http://www.juanholgado.com/ (Spanish blog with lots of route alternatives around Rodellar and Alquezar, Search under "senderismo" for sendero historico or click pirineos, pirineos centrales and scroll down for Sierra de Guara) The Cicerone GR1 book is also good but aimed squarely at people staying at B&Bs. Editorial Alpina produce an excellent 1:40 K map of the Sierra de Guara park with a guidebook in Spanish and French.
