Work, view, work. This is the not quite detailed summary of the tour!

After rolling in from Wimmis, the ascent begins on the sunny slope near Reichenbach. The ramp up to the summit is steep. At the latest when the gradient is "only" 10% and you have the feeling that you are going straight up, you are in quite steep terrain. As described, the approach to the Niesengrad is mostly on paved roads. The last 200 meters are covered by pushing and carrying. If you've had enough here, take the trail to Wimmis. If you still have enough energy left, the ascent to Niesen Kulm is worthwhile. The view is like a painting, the amazement of the train passengers that bikers are struggling up here is priceless.

The descent to the Niesengrat is mostly S4. If it weren't for the tedious rain gutters made of tree trunks, you might even feel like you're going with the flow. But no - work, concentration, a keen eye.
From the Niesengrat ridge, the route continues at S4 level. Not because the terrain is generally steep and challenging. Some of the paths are less than the width of a towel, overgrown and there are plate-sized stones underneath that will knock you off your handlebars. Loose rocks in masses don't make it any easier.
From the middle, something like a built bike trail begins in steep terrain, which alternates with hiking trails.

Conclusion: The view is outstanding. If you like S4 trails where you have to work and can't just slide down, then this is the place for you. You have to do it once in your life!!!

Rode yesterday: Ascent steep and long. Carrying passage easily doable up to the ridge. From there to the Niesenspitz is 1 hour of pushing and/or carrying. The view is worth it. The descent to the ridge is 4/6, but everything is rideable, but the gullies are a challenge.
The descent from the ridge is very steep and very rocky. At times you feel like you're in a rock garden. The steepness and the terrain continue until about 300m above Wimmis, then it becomes a bit more flowy.
Conclusion: Very challenging, beautiful view, does not need to be repeated

Super tour as described in the April issue.
At the moment the whole descent is good to ride.

A long time ago you could book the Niesen by shuttle.

It's a fantastic descent and if you can rock it twice in one day, the fun factor is even higher. But unfortunately, those days are over and if you want to ski down the Niesen, you have to conquer the mountain under your own steam.

The ascent is beautiful and strenuous but worthwhile. I was very disappointed with the descent. The first half is barely rideable and was one of the hardest I've ever ridden. After about half of it there is a short fun section and the last 6 km are unfortunately on tar again. The best singletrail is from the Niesen summit back to the original trail. The almost 400 additional meters in altitude to the summit are well worth it, even if you have to carry your bike the whole time. It's not easy, but it's definitely the highlight of the whole route.

Rode on June 19, 22. great tour with a pleasant ascent and a fun (if not easy) descent.

I think the path to Alp Oberniesen is new; at least it is not described here and not marked on most maps. In other words: you can ride up to there without any problems. The pushing/carrying part is thus reduced to a short and pleasant 200m.

The descent is - probably also thanks to the cows - quite tricky at the top. I can well imagine that it's not quite as much fun when wet.

We rode the tour on 22.5.22. From the alpine huts at 1814m.a.s.l. you have to push or carry. It is definitely worth it. The descent to Wimmis is all rideable (s2), with a few rough sections and is very varied. Absolutely worthwhile - the brazilien in the Oberland...

Ridden on 03.10.2021 without any problems! The woodwork does not affect the bike route. They are on the side of the Niesenbahn. Only towards the end of the trail, on the last 300 downhill meters (you ride behind a hut at the beginning), the entrance to the trail is closed off with a tarpaulin. But it's not a problem, you can re-enter the trail about 50m further down and then ride down without any problems. There were only 2 felled trees on the trail, but you can easily ride around or climb over them!

According to Schweiz Mobil, the exit to Wimmis is closed until the end of Oct 2021 due to timber work.

Climbed at the weekend. The ascent was actually pleasant until the last part, which is definitely not rideable. The descent was already very icy and in the snow, but still brilliant!

I rode the tour for the first time today, a long ascent but rewarded with a brilliant descent.

I've ridden the tour a few times now (every year). It's always an experience. The slog to the summit is really nourishing. Carrying, pushing and carrying again. It's actually quite enough to reach the Niesensattel, but the view and the subsequent descent are magnificent! With an enduro bike with 180 mm of suspension travel, everything can be flattened, even the technically demanding sections.

I did the tour yesterday. The muddy parts are now reduced to a few places in the forest, and you can go around them, so it's practically rideable throughout. Definitely up to the summit, it's worth it!

HOWEVER, right at the beginning, the tour leads through a company site where unauthorized access is prohibited and also very dangerous (gravel and concrete trucks everywhere). Just drive straight ahead and turn left a few hundred meters further on.

I can confirm the statement by "mirjam.luethy_36918 on June 22, 2020." confirm: The path between the alpine huts at approx. 1700 m above sea level and the Bärgli, approx. 1300 m above sea level, is in very poor condition (muddy and full of holes from the cows)
The bikers are ruining the paths....

Unfortunately, the descent in the upper part is a huge muddy mess at the moment, due to cow trampling and very wet pastures. Have pushed down about 400 m to 'Bärgli'. Good riding from there. I can imagine that the hiking trail will not be very fun to ride for much longer, as it has suffered a lot from the cows...

Checked 2019

We rode the tour in beautiful fall weather. For the last 300m the bike always has to be pushed (not "again and again"). This effort is worth it, because the descent to Wimmis is awesome!
I will certainly do this tour again.
