Seldom does anyone come here, you can tell by the overgrown path, the last few meters to Inn Spitz have to be covered on foot, but it is worth it.

In one of the photos you can see the sign "Fish Limit". Hope the fish can read this. The sign is probably not intended for anglers, because who would want to eat a fish from the poisonous Alz?

@Reparl: Definitely not suitable for e-bikes or pedelecs. The electronics in it are afraid of water :-) And in the cold season, you should take off your shoes and socks and hopefully have a towel in your luggage.
