From the top of the Niederrickenbach Cable Car walk to the right through the town, past the convent and keep going on the road that traverses the hill into the back of the valley towards the bridge just below Alpboden. Cross the bridge and walk uphill a short distance before turning left and following the road (snow covered if it's a good day!) to the bottom of the lift.
On a busy day there will be a long que and expect to wait a long time for the lift. If it's quiet you may beed to use the telephone at the bottom of the lift to inform them that you want to get up. You pay once you get to the top. (The last time I was there it was 12CHF for the first run, 8CHF for the second and 5CHF for each run after that).
You can drop in on both sides of the Restaurant at the top of the lift. Skiers right leads to a big open powderfield that narrows up as you drop down to the tree line. Skiers left is a bit flatter to start with and then it gets slightly steeper but has more rocks and other small obstacles in the way. Both ways lead back together through the trees as you come to the bottom of the lift.
There is a wildlife protection zone about 500m to the west of the top of the lift. Do not drop into the little valley from Giri to Bockihüttli on the map. Rangers have been known to hide in the trees to fine freeriders using this line.
If you want to ski to the valley keep going west along the ridge past Giri and climb to point 1923. From here traverse Northwest between Gigi and Gigichrüz. From here you can ski Northwestwards past Oberist, Mittlist and Unterist Hüttis. At Bortlers Landfluh take the road the whole way down to the valley station if there is enough snow.
