Not a trail but for those interested, road/gravel there is this one….(Northern America kind of…)

Vegan cyclist doing the climb here…..

I rode over Pico del Veleta (3,400m) in the Sierra Nevadas. I thought I was dying at the summit.

Piz Umbrail above Selvio is 3033m:

Barrhorn at 3570m is pretty impressive:

If you want ridable climbs (why?)… then this is a good list:

@nedrapier Haha, that predictable!?! I don’t think the lad in the video rode much of the down there… Papy has a penchant for riding hills that are rubbish to ride, until recently on a old GT DH bike, or the worst possible bike to carry up there in the first place. He’s ticked off the Argy glacier and plenty gravelly peaks in Switzerland, and after a bit of searching, the Bishorn 4153m (13625 foot / 80 Nelsons columns for the imperialphiles) https://www.youtube.com/watch?v=fR7lLcCLRX4

It doesn’t exactly meet the “trail” requirements though!

Not Europe, but I have ridden over this trail, just shy of 5020m, a on a rigid bike with panniers. I think I did have Flexstem though. It was crushingly hard work.

Bolivia!

There will be a number of places on the altiplano where a road goes to 5000 m +

the one I want to do is the route from the bolivian boarder down to Arica in chile 3000+ m of descent mainly in 60km, 60 km downhill!

Piz Umbrai is awesome, rode that 2 years ago
I would say the best High Alpine trail I have ridden is The Banzai trail in Cogne, Aosta
Officially called Passo Invergneux – 1500m of sublime singletrack from 3000m back to Cogne Village

Gornegrat in Zermat is pretty cool at 3000ish, ride up on the train and great trails down

And by highest I mean altitude above sea level

Sea level where?

@the00 It’d be really interesting to see that full list of bikable 3000’ers, especially as one persons bikable is another persons evening infront of the screen watching Danny MacAskill…
I can think of plenty of trails that are above 3000m but not that many that start from a peak.

Me too, but with a brief google I didn’t find it. Seeing as they include the Matterhorn itself then I am sure that some of them are pretty hairy.

Not ridable up, but hike up and ride down the Oberrothorn near Zermatt. 3413m.

It will be something in the Caucasus or Urals i would think

Ive walked a very ridable tral at 3700m in 5hw andes and i know of a landrover track to 5000m again in the andes
