Easy hike to the highest peak in Vorkarwendel. The ridge from Schöttelkar to Soiernspitze is recommended alone for the views.
A nice bonus is the scree field descent from Soiernscharte to Soiernsee. It is in parts more a talus field than a scree field with up to 40° steepness or more. Without snow keep an eye on your fellow hikers above you to avoid falling rocks.
Snow can make it easier: "No timid steps allowed"(as freedom of the hills knows).
This path may be better prepared later in the season.
After the beautiful Lakaiensteig a rather dull descent from Fischbachalm follows - Herrsching to Kloster Andechs multiplied.
This can be avoided by parking your bike there beforehand.
