When IMBA Europe, the umbrella organisation for all European bikers, invites people to a summit meeting once a year, it prefers to take place where there are already perfect trails. After all, this conference brings together trail builders, organisations such as the DIMB, tourism representatives and industry professionals who want to promote the sport of mountain biking in their own country. In addition to workshops and presentations, participants will also be able to get out on the trails over the three days. It makes sense to choose a spot that has already created a top infrastructure for mountain bikers and sets a good example.
This year, the IMBA Europe conference will take place on 16-18 September in a small town called Boltaña in the northern Spanish province of Huesca. The municipality lies at an altitude of 643 metres in the pre-Pyrenees and is surrounded by five exciting bike spots that have proclaimed themselves the "5 Bike Kingdoms of Huesca". These are five trail centres at different altitudes, with five different characters. What they have in common, however: They are open all year round and are perfect as autumn and winter destinations for anyone who wants to extend their biking season or not let it end at all. And the long journey is worth it, because there are plenty of places to visit in Huesca:
- 280 designated routes
- 3350 kilometres of trail network
- Altitudes from 400 to 2700 metres
And these are the individual spots in the Spanish Pyrenees with their different characters:
1. Los Mallos Bike Kingdom
You have to marvel at the spectacular Mallos rocks in the north-west of the province of Huesca from up close anyway. They tower like a giant crown over the small town of Agüero into the sky. A 300-metre-high bastion of rock needles, which is located in the small neighbouring villages with the Mallos de Riglos and Peña Rueba.
This sensational backdrop alone makes the enduro routes in this region particularly popular. The best starting points for the 6 designated, technically demanding routes: Mallos de Agüero, Mallos de Riglos, Foz de Salinas, Sierra de Loarre and Santa Eulalia de Gállego. Also exciting: the "Refollau" circuit, which was also signposted in Ayerbe in 2021.
Easier trails can be found along the La Sotonera reservoir, in the hills of Biscarrués and on the banks of the Gállego river near Ayerbe. Or you can pump your legs on the Bolea marathon course. The 40-kilometre route leads through the Sierra Caballera, covering almost 1100 metres in altitude. There are no trails on this route, but the Spanish tracks cannot be compared with the forest roads of the Alps. They are sometimes wider sandy tracks through the pine forests, but then climb narrow and washed out up the mountain flanks.
There are no ascent aids in Spanish trail centres either, making metres in altitude is traditionally part of the flow here. Which is a welcome source of warmth in the winter months anyway.
Info Los Mallos Bike Kingdom
- How to get there: 30 km from Huesca, 100 km from Zaragoza
- Trail Centre: 11 routes (including 6 enduro)
- Total trail network length: 40 kilometres
- Character: partly stepped trails uphill and downhill. North-facing mountain flanks through pine and oak forests, south-facing dusty and rocky terrain.
2. guara kingdom BGuara
National park scenery! The Sierra de Guara is criss-crossed by canyon-like gorges, through which you can venture into the centre of Aragon's largest national park area on seemingly endless trails. A western landscape flanked by gigantic rock faces. Highest peak: Pico de Guara, 2077 m.
This is an area that has to be shared with racing cyclists and gravel bikers, as the gorges of this mountain ridge are criss-crossed by particularly wild tarmac bends. On the other hand, the infrastructure for cyclists is particularly well developed here. There are good places to stop for refreshments and bike shops in the medieval alleyways of the villages.
Info Kingdom BGuara
- Trail Centre: 34 routes (16 of which are enduro)
- Total trail network length: 267 kilometres
- Character: limestone and sandstone cliffs on the southern slopes of the national park, mixed forest on the northern slopes, canyons, trails up to over 2000 metres altitude, very varied landscape, routes of all levels of difficulty
3. Sobrarbe Kingdom Zona Zero
When the trail builders began developing their first trail circuits in 2011, nobody could have imagined that this Enduro Trail Centre would expand to such an extent. This network of trails now stretches over 2500 kilometres through desert-like sand humps, passes abandoned villages, penetrates the most remote valleys and climbs up panoramic ridges. The landscape changes its faces as the trail biker changes gears. A constant up and down with ever-changing enduro challenges such as steps, loose scree, exposure and gradients. From a short trail quickie to a 9-hour epic ride, anything is possible here. In winter, a few snowflakes might actually fly here, but the trails around Biello Sobrarbe remain mostly dry and definitely always rideable.
Info Kingdom Zona Zero Pirineos
- Trail Centre: 133 routes (72 of which are enduro)
- Total trail network length: more than 2500 kilometres
- Character: Perhaps the largest network of trails in Europe, through wilderness, through the Ordesa National Park and up into high alpine terrain. The Enduro World Series also makes a stop on these often challenging trails.
4th Alto Gállego MTB Kingdom
This area stretches from the main ridge of the Pyrenees to the foothills of Biescas, following the Gállego mountain river on its long journey down to the Ebro. In other words, from high alpine super-panoramic scenery on the French border down to the sandy foothills of Biescas. You couldn't ask for more scenic variety and the Panticosa Bike Park awaits in Aramón!
Info Gállego MTB Kingdom
- Trail Centre: 58 routes (including 31 enduro, 6 downhill lines in the Panticosa Bike Park)
- Total trail network length: 300 kilometres
- Character: Natural enduro, all-mountain and marathon routes in the main ridge of the Pyrenees, around mountain lake areas and through forests, but also a desert atmosphere in the lower region, Ordesa-Viñamala Biosphere Reserve
5th Aneto Kingdom Puro Pirineo
This spot drapes its 25 enduro laps exclusively in the main ridge of the Pyrenees. A total of sixty 3000 metre peaks decorate the surrounding area. A good level of fitness is an advantage, as are solid riding technique skills. There are also gravel bike routes along the river valleys, but to get to the true and wild natural beauty of the region, you should have your bike well under control.
Info Aneto Kingdom
- Trail Centre: 52 routes (25 of which are enduro)
- Total trail network length: 250 kilometres
- Character: Due to the altitude, there may be snow in the region from December to April. However, in lower areas, such as the Benasque Valley and the region around Turbón Mágico, the trails are rideable throughout the winter.
