The Gran Trail Collserola presented by Barcelona Trail Races (originally known as “Ultratrail Collserola”) is Barcelona’s backyard ultra trail race. Covering 76km and climbing over 2,600m, this isn’t the steepest ultra that you’ll ever race… but if you approach it complacently, it will destroy you!

Carretera de Les Aigues is a flat gravel road that twists and turns along the side of the Collserola mountains. This flat gravel bench cut into the mountainside runs for miles at roughly the mid-mountain elevation. From the road, you’ll enjoy stunning views of Barcelona spread out below you, flanked by the bright blue waters of the Mediterranean!

This point-to-point route running from the outskirts of Barcelona all the way to the train station in Sant Cugat des Valles is an inspiring trek through the mountains of Collserola. While you'll catch the train back from Sant Cugat, you'll shirk the free elevation gain from the funicular and, instead, climb the mountains and cross the entire range on foot!

This short loop following the two Muralla China trails is located just on the other side of the ridge from Barcelona. While it isn’t far from the city, being on the backside of the ridge and away from the more touristy area on el Tibidabo does help keep this trail a bit quieter than some others in the region.

This delightful point-to-point run climbs from the Trinitat Nova train station to the crest of the Collserola Mountains, and then traverses the crest all the way to the Vallvidrerar Funicular. With a lot of up-and-down sections along the way, you’ll gain over 2,000 feet of elevation along this 7.5-mile route.

This medium-length loop through the northern reaches of Collserola begins conveniently right on the edge of Barcelona. The route climbs up over the mountain range, drops deep into the forest on the far side, and then loops back up and over the mountain to return to Barcelona.

This recommended loop connects some of the most popular trails in the easily-accessible Tibidabo zone of Collserola. The run begins at the mid-station of the Valvidrera Funicular, which gets you halfway up the mountain. You’ll start running on the flat gravel road known as Carretera de Les Aigues—one of the most popular routes in the region.

The urbanity of downtown Barcelona transitions to the dense undergrowth of Collserola shockingly quick! In a matter of minutes, you can ride from soaring buildings to deep forest solitude. Most of the Collserola mountain range has been designated as a national park, known as Parc de Collserola. Despite being surrounded by cities on all sides, this massive park covers over 8,295 hectares of protected land. You can reach the park by foot, bike, car, funicular, or the metro lines.
