October 11, 2025,Isartal – Isartal bei Vorderriss Runde von Jachenau

Really nice tour, varied, some steep sections, nice trails, beautiful views, easy to ride with the E-MTB, at times there was heavy loose gravel to cross, not so easy to ride with thin tires and without a battery.

The start was at the large parking lot in Vorderriss; the first few kilometers are on a gravel path uphill through the forest. Then it continues through a spectacular landscape along the Isar River. In glorious weather, you can recharge your batteries with food and drinks in Mittenwald's lovely old town.

How the maximum speed came about is a mystery to me. We weren't going that fast...😂
Unfortunately, I can't upload all the photos. I don't know if it's due to the poor internet connection. I'll upload them later.

September 18, 2025,Vorderriß - Mittenwald Gröblalm Windbeutel

In glorious autumn weather, we headed along the Isar River to Mittenwald. We followed wonderful paths to the violin-making town. We stopped off at the Gröblalm inn. Highly recommended; the cream puffs are world-class. The hilly meadows were a visual highlight. All in all, a dream day.

Caution! There is a single trail on the ascent. Only for experienced mountain climbers. The key point is exposed, slippery and only 40cm wide. Personally, as a cyclist, I would only do this route out of season or during the week. I imagine being stressful when hikers come towards me all the time. And vice versa, of course. Am a …

July 29, 2022,Zur Fischbachalm und Soiernweg

As is often the case in the Alps, this tour also started with a never-ending climb, which then got really steep as a reward at the end (strangely enough, Komoot doesn't show the correct 24% incline). But the cows on the Fischbachalm greeted us a little more intrusively than we would have liked 😝
The Soiernweg that came afterwards is …
