Val Gronda

Tour Val Gronda

The tour from Lumbrein through the Val Gronda to Trun is one of the most beautiful alpine routes in the Surselva district of Graubünden. From the pleasant main ascent with a hike-a-bike at the end, wonderful views and wildly beautiful landscapes to great but also challenging single trails from the highest to the lowest point, this tour offers everything.


Description

The route starts in Lumbrein, where you roll a little further into the valley on the main route. The warm-up ends at Sogn Gion and the ascent begins. The first 500 of around 900 vertical meters are covered on the pleasantly ascending alpine road before it turns into a 4x4 alpine trail at the lower Alp Cavel (Tegia Sut). From the upper alp (Tegia Sura), you then have to shoulder your bike. Mostly without a path, you follow the hiking trail markings to the culmination point, the Il Bass mountain crossing. Here you are not only rewarded with a magnificent view of mountain peaks such as Piz Aul and Val Gronda. The first descent also leads through the striking rock band that closes off the valley. The trail is mostly easy to ride, but has a few tricky sections, including a practically unrideable step. A head for heights plus very good and safe riding technique are a must here. After this section, the route leads over pathless terrain for a few hundred meters, after which you return to the trail that rides parallel to the valley floor from Val Gronda. From Vorderalp, the trail widens and the descent becomes faster, before you are challenged again with the "Bim bösen Tritt". Once again, there are easier sections on wider trails and forest paths. The final section to Hanschahüs is a trail highlight par excellence, and it leads directly to the bus stop on the main road at Lumneins Dado. If you don't want to get on here, roll out for a few more minutes and finish the tour at Trun or Tavanasa train stations.

Did the tour three days ago. And I would agree with the description except for the pass. Really great views on the pass and when you look along the trail it makes you want more! It looks adventurous.

In reality, however, the trail is rather rough. So I think technique 4 is a bit of an understatement, it's a bit more blocked and even with transfers and hops you can't get down without dismounting and carrying passages. After a few up-down-up-down passages have been conquered, the trail opens up and becomes a double track for the most part. This was very disappointing.
Apart from the view, I can't recommend this tour, it wasn't worth the long journey for me. The trails near Thusis are just so beautiful and much more fun to thunder down.

400m of pushing on a very steep gravel road and over mostly pathless meadow terrain.
The descent to Oberhitta 2154m would be nice in principle, but is overgrown over long stretches.
After that, work was done on the high trail and a nice S1-2 trail up to 1980m was created.
After that solala meadow & forest trails on rather wider paths. Final trail again very nice.
Conclusion: You can save yourself the pass and ride directly from Obersaxen on a gravel road to "Oberhitta".

Did the tour on October 31, 2022 and Donat's description is perfect. The scenery is an unparalleled highlight, while the trails down to Tavanasa take a bit of getting used to. As Donat writes: sometimes smooth to ride, sometimes rather tough. - In this respect, my comment would be superfluous if it weren't for the Grener Bach and another torrent (nameless). At this time of year, the bridges on both streams had already been dismantled. So there you are, at a loss. Back or what? Not at all. You look for a place that you can somehow pass by using your bike as walking poles. As long as the stones aren't icy, the crossing works somehow when they are icy: no chance. Apart from putting your shoes and socks in your rucksack, grit your teeth and look for a firm foothold in the raging water.

Very pleasant forest road from Lumbrein to Alp Cavel. Then it's time to push and find the hiking trail. At the top, an incredibly beautiful landscape with views of Lumnezia and Val Gronda. The descent into the Val Gronda is a bit tricky, but very beautiful. Then it's a bit of an arduous climb up the left side of Val Gronda. From there it becomes smoother, the landscape remains beautiful. Then some forest road and then really great trails down to Lumneins. I was virtually alone on the whole route. The tour is definitely worth it!
