This trip is the easiest canyoning that can be done. No need for swimming necessary but you need to be capable to jump into water. The security vest will make you float without any problems (YOU HAVE TO TELL THE CANYONEERING GUY THAT YOU CANNOT SWIM AND INSIST THAT YOU NEED A SECURITY VEST!)
Here is the description of the event:
_Take a train to Peissenberg (about 1 hour, not included in cost, will be a simple shared Bayern ticket)
_Equipment handing out and first introduction by certified mountaineer (included in price, wet suit + wet socks will be provided, all you need is bathing suit/swim wear and a pair of shoes that can get wet).
_ Shuttle to canyon (about 1 hour of trip. included in price)

_Shuttle back to Peissenberg (again about 1 hour, included in price)
