According to locals, the carbon trail is still a lot of fun (as of 29.9.25)

We rode the tour yesterday. The inn at the start of the Carbon Trail has since closed & is for sale. The Carbon Trail is no longer maintained. It still has great sections, but can no longer match the trail fireworks of the past.

Ingenious trail. Great trail cinema! We rode the tour on July 2, 2023 and if you read the comments, you might get the impression that almost the entire 22 km of trail is overgrown and will soon disappear. This is by no means the case. The trail has only been relocated for just under 1 (!) kilometer - at the first alp after the Basso di Montoia (i.e. the wide ridge ridge after the descent from Monte Tamaro, where you turn 90° to the west = right) you now cross the slope below the alp and no longer above it. Everything else is still in great shape and quite fun.

Can only confirm the positive comments. We rode the whole tour on 23.09.22.
Absolutely brilliant, even the lower part (carbon trail) was clean.

Best regards

A great tour, even if the ascent is quite demanding.
At the first alp after the Basso di Montoia, the marked path is overgrown and, according to the alpine innkeeper, is no longer maintained. Take the alpine path up to point 1562. I would classify this as S2.

Ridden on 18.6.2022
Absolutely top condition, a firework of a trail, clearly one of the best trails ever in Ticino. Many thanks to the trail builders! With very few exceptions, no major difficulties, occasionally a nasty hairpin bend. Thanks to the e-bike, even the ascent is fun. Thank you!

Can anyone say what the current condition is?

I rode the Carbon Trail again today 29.7.2020 exactly one year later. Although the trail is now officially closed, it was in the same condition as a year ago. Very varied and wonderful to ride due to the dry surface. Well, most of it anyway. I had to walk certain uphill sections. And the upper part doesn't seem to be completely safe because of the steeply sloping terrain (next to the trail). But the sensational view and the adventurous descent are somehow unbeatable. I will gladly ride the route again if possible.

June 19, 2020, unfortunately there is still woodwork in progress on the carbon trail. Had to switch to the road. The trail was rideable until the crossing of the stream, but has definitely seen better times!

Otherwise a great tour.
But the climb from the mountain station to the antenna is a tough one!

A fantastic tour for lovers of technical, varied single trails... I really enjoyed it!
Certainly not for beginners or flow fanatics, but with the necessary riding technique, good line choice and a little self-confidence in some places, practically everything is rideable. From the Alpe di Trecciura onwards at the latest, the new carbon trail is simply endless fun - the trail builders have done a great job! It's certainly one of the best trails I've ridden in Switzerland in recent years!
Alternatively, you could probably ride around Monte Tamaro on the right and then head straight to Alpe di Neggia without any counter-climb... Has anyone already tried this?

Were there yesterday (31.03.2019). The entrance still had very little snow. In the upper part in the forest there is still a lot of foliage - blind riding :-). The trail is closed until the end of the first week of April due to logging during the week!

Attention: The alpe di neggia trail is currently closed due to woodwork. Oct 2018 -Nov 2018. see also on ticino.ch.

The Carbon Trail has been completely rebuilt. The difficult passages have been defused and now it's awesome, one of my favorite trails in the region! ATTENTION Do not miss the descent to Vira Gambarogno (official), the trail towards Quartino is blocked at the end and is not so much fun.
Have fun discovering the new trail!

So I tackled this tour today. After constant bad weather in the north, I needed some sun. Rode from Zurich to Quartino (where the tour ends) in about 2.5 hours. Parked the car there. Then up the old Roman road to Riviera. This is not an official part of the tour, but easier for logistical reasons. The Roman path is relatively steep and ideal for waking up. However, you need to be a bit practiced to be able to ride it all.
In Riviera I took the gondola to Alpe Foppa. Costs CHF 20 incl. bike.
Now the official part of the tour begins! The ascent to the antenna is relatively steep, but can be ridden well (I would describe myself more as an advanced rider, technically as well as conditionally, bike: YT Jeffsy 29er, 140mm).
The following trails up to Monti Idacca are rather technical and not very flowy. Apart from a few isolated sections, I was able to ride everything well (it should be noted that this is basically a very technical tour and definitely not for beginners).
Then it's up the road to Alp Neggia. This is followed by some very fun trails. But it still remains technical.
On the last descent there is a passage that was clearly not rideable for me. This is about 300m long. Really steep and blocked. It is basically rideable, but only with advanced trial skills.
Overall, the tour is very scenic. At the start at Monte Tamaro you meet a few hikers. The rest of the tour I was on my own.
In general, it is more of a technical tour and only a few trails are flowy. It is advisable to ride very cleanly as there are a lot of sharp stones. The 29er was therefore the ideal choice. Total time expenditure 4.5h, pure riding time 3.5h.
I am at your disposal for any questions!

You need exceptionally good technical riding technique to ride even half of it. Up to Alpe di Montoia, the trails are barely rideable. Later, there are really nice, (short) flowing trails, but these are repeatedly interrupted by unrideable sections. After Bruno there is a really nice trail along the slope. However, the descent to Quartino is not rideable - unless your name is Danny Macaskill.
