Yes pls. It’s open. Only thing you may not be able to see the waterfall.

You can access from either Germany or Austria. The Austrian address is Schanz 273a, Leutasch, Austria. There is a parking lot and visitor center. From Germany (Mittenwald), I encourage you to park in one of the many public parking lots and walk to the entrance. Follow Innsbrucker Str. There is a pedestrian only turnoff on the North side of the Isar River crossing. The walk is about 1km from this juncture.

There is a steep climb for the first 1km or so. Otherwise the trail is easy. I recommend 1-2 hours.

It’s available to walk around at anytime, but you will need sunlight and the cafes/facilities are probably 8-6 during the main season.

Der Wasserfallsteig ist nur in den warmen Sommermonaten geöffnet. Im Winter ist die Gefahr durch Eis, Schnee und Gesteinsschlag zu groß. In dieser Zeit kann die Leutaschklamm aber im oberen Teil (Klammgeistweg, Koboldpfad) begangen werden. Die moderne Konstruktion verhindert das Vereisen der Wege. Dennoch kann es bei starken Schneefällen oder Reparaturarbeiten zur Schließung der Leutaschklamm kommen. Informieren Sie sich deshalb am besten bei Ihrem Gastgeber oder bei der Touristeninformation über den aktuellen Stand in der Leutaschklamm.

Мы заезжали с австрийской стороны. Это было в конце апреля. Никакой платы за вход не было. Платили только за парковку. По времени - мы прошли все ущелье и спустились с немецкой стороны, затем посетили кафе (пообедали) и вернулись почти тем же путём в Австрию. На все это примерно ушло часа 3-3,5

We walked from the center of the city, its not that far, there's a couple of signs (in german) its nice and flat until you reach the hike, but then it goes uphill and I wouldn't. Call it a hard walk, but I'm only 28 years old and got a bit sweat on my face hehe. Not much to do in mittenwald really, but that's exactly what's great about it. It's the atmosphere and great landscape around it. A small place of well kept bayrisch culture :-)
