The Upper Alley is a run under the Paradise Chair with large moguls.
Ascend the Paradise chair and descend the Paradise Bowl or the Fenceline Gully and head directly under the chair.
Once the trees begin you are in Upper Alley.
The bumps are large underneath this chair some formed by natural features.
This area tends to see a lot of traffic so the moguls are usually quite large.
You can descend the entire chair line meeting up with Alley and back down to the Paradise chair.
A good option in the Paradise area if you like bumps.
