Gallaströmmen is quite wide and calm stream located a bit down stream from Vatjinavveströmmen from where you can see the start of the rapid, The riverside is a bit hard to pass through on the west side as you can see on the photos and it's a bit to walk toreach the stream.
Gallaströmmen is one of the less popular fishing spots in the Arjeplog streams what I experienced so if it appears to be too crowded in the other streams, it could be a place to go to. Nice greyling catches have been reported from Gallaströmmen.
You can see the bridge over Vatjinavveströmmen on distance.
