The Trans Swiss Hiking Trails are already on the Forum, but the link might be more easily found here. This one is to the Trans Swiss Trail 1. The other Trails are listed with the appropriate links at the very bottom of the page.
Unfortunately this part of the Wandersite is not in English but some of the info will be clear enough from the place names alone.
The parts we have already hiked along were very well marked and well-walked.
Happy hiking!
