FATMAP difficulty grade
This one is a classic for the local mountain guides.
With a guide, they take you up with skis/board with Valluga II.
If you are without a guide, you have to earn it.
Time for heroes, put your gf into the gondola and hike carrying your and her skis/board.
First climbing up west, then along the ridge.
The ascent takes 30-40 minutes depending on how deep the snow is (the classic West face has a FatMap entry already, just drop over once you reach the ridge - and only if you haven't put your gf into the gondola to the peak :)).
From the ridge there is a variety of options if the snow is good.
A beautiful one starts almost at the peak under the bridge, steep, but nothing crazy - needs good snow.
The classic north face starts actually right behind the peak.

The first patch of the Valluga North is exposed with a cliff below.
The rumour has it that they closed the second part for non-guide accompanied skiers due to accidents.
Prior to the opening of the Flexen Gondola this (and Valluga West) used to be the way to get over to Lech/Zuers. Now, with Warth/Schroecken connected, you can actually ski the entire north face of the Valluga as well down towards Kaisers and the Steeg and back to Warth.
But - the exit is long.
Only recommended if you don't mind long flat sections and get a kick out of purely nice scenery.
