I have a weekend between two work weeks in Zurich and would like to spend some time walking along river gorges. I have done hiking/cable car+boat rides and thus this would be new to me. I did enjoy walking along some river gorges in Austria and now want to do it in Switzerland too. Besides, I need to escape the muggy air trapped in downtown Zurich.
I don't have a ton of luggage space and want to avoid bringing my hiking boots. Will normal running shoes suffice? I believe those "trails" along river gorges such as Are Gorge are not rugged. Thanks.
