GLR 21 Route info
GLR 21 Region
With the GLR 21 you’ll dive into the transit zone from the green Spanish region down into the semi-arid interior. Explore the Navarre and Huesca provinces down below!
Huesca
Navarre
Adventurising isn’t only about getting as fast from A to B! A Region has so much more to offer! That’s why I give you some suggestions about things to do while Adventurising the GLR 21.
Mallos de Riglos
You’ll see this beautiful red rock formation from quite afar! It’ll lure you closer and closer until you’re standing at the base gazing up. Visit the Mallos de Riglos during sunset and you’re treated with a beautiful array of colors!

Fort Portalet
Fort Portalet was built to guard the French Pyrenees border and to protect the access to the Col du Somport. Construction began in 1842 and finished in 1870. From then on it saw use through the first and second world wars. Nowadays the local government tries to restore this fortification to its old glory.

Pic d’Orhy
Mount Orhy is the westernmost peak above the 2000m mark. This mountain located on the border between France and Spain has an important role in Basque mythology. On a good day, it’s possible to summit the mountain via 6 different routes.

Urkulu
Another mountain pass connecting France and Spain with some ancient History. Right at the top of the Urkulu mountain, you find some romanesque ruins. Take this slight detour when you cross the border over the Pyrenees.

Connections in Jaca
You’ve completed the GLR 21 down south and you want more! The GLR 22 will lead you east. This 327-kilometer long route is the route most people use for their Trans-Pyrenean adventure. With 103 kilometers of off-road sections, this motorcycle adventure route won’t disappoint!
If you want to progress a little further to the south, the GLR 24 will guide you. This 182 km long route guides you through the Huesca province of Spain. With stricter off-roading legislation, this route sports only a little less than 39 kilometers of off-road sections.
Connections in Orbaizeta
You’ve just crossed the interior of the Spanish Pyrenees and you can’t get enough of the Spanish roads. That’s great because the GLR 25 will continue your motorcycle adventure for no less than 659 kilometers. This great GLR will loop around to the west. More than half the distance will be traversed over off-road sections. Personally, this is one of my favorite GLRs!
But don’t worry! If you have enough of Spain and you want to head into France, I have the GLR 20 for you. This motorcycle route will guide you through the Pyrenees to the east. This 371-kilometer long GLR is a great alternative for the Spanish Trans-Pyrenees route. Although France is a little more strict in off-road laws, this route will traverse for 56 kilometers off-road.
