There's a great drink station here! Easy to miss but signposted. Beer, soda, spritzer. Humane prices and great view! Don't miss it!

The two red, steep sections are much better with E, but your pulse will still rise slightly.

Pleasure tour of Fleck to Sylvenstein, back via

the Röhlmosbach + Jachen valley (pure nature).

Start near Langeneck on a quiet free

Parking off St2072.

The section in the Schronbachtal is a hiking trail

but highly recommended as a break because of the scenery

and Gumpen/Waterfall at the end, only goes on foot.

It's hard to believe that the round went so early in the year😱 Even though it was very slippery at times, it was super nice in the sun ☀️felt like 20" 🙋🏼‍♂️

Showing Translation

Blue and white Bavarian weather.

Modified tour from 20220815, but
again 3 impassable dead ends,
see pictures.


Otherwise a very popular round trip.

Part to and on the Jachen not suitable for a gravel bike.

Gravel bike recommendation on the Röhlmoosbach directly
straight ahead at RehgrabenAlm, steep descent
into the Jachental, see pictures.

Great, extensive tour that is very, very scenic. Various great views! Suitable for More like something if you want to do kilometers, because little to no technical requirement. But it doesn't have to be in the S1 S2 either ... was fun!

A relaxing bathing trip from Lengries, well it wasn't quite that relaxing, but there were definitely nice places to swim and a lot of fun. The area around the Sylvenstein reservoir is always worth it 😃
