Before the new base tunnel was opened in 2007, the main train line slowly descended the site of the Rhone valley until it reached the floor at Brig. While it's still possible to take the train along this scenic route, it's nicer to get out at one of the stations and walk along the trail which follows the train route. While the whole trail is very long, it's possible (and recommended) to only walk a part of it. Between Hohtenn and Brig, there are several train stations (Ausserberg, Eggerberg und Lalden) at which it is possible to catch a train in either direction (hourly). This trail offers nice panoramic views on the Rhone valley through the arid and scarcely vegetated sunny side of the valley. Due to its exposed nature it can get scorching hot in the summer months and while it's still possible to do the hike, autumn usually offers milder temperatures and views in autumn colours. It is also an ideal place to explore some of the impressive watering channels (locally called Suonen).
