The 1b is an alternative run for the Red 1.
The slope will start after the first sharp turns of the 1.
The 1 then continues straight for about 600 meters after which it will split into two slopes.
On the right side you will find the 1b.
It's a short, relatively wide, steep slope.
Due to the fact that most tourist head up the Gaislachkogl for the beautiful view and architecture the Black 1b stays mainly untouched.
The slope is awesome to make the run down from Gaislachkogl a little bit more challenging and fun.
The slope then reconnects with the 1, where you can join the crowds and continue your way down the mountain.
