Dwoista Siklawa is one of the highest waterfalls in Poland with a total height of 80 meter. Dwoista Siklawa is located south of Lysa Polana, near lake Morskie Oko.
There is a trail starting at the hostel Morskie Oko, along the lake to Czarnostawianska Siklawa. Near the end of the lake you can see Dwoista Siklawa at the other side of the lake. It is possible to walk around the lake to the base of the waterfall. Dwoista Siklawa can be reached in 50 minutes.
Dwoista Siklawa are actually two waterfall in the same river, close to each other. But only the lower part is known as Dwoista Siklawa. The river Mnichowy plunges down over 80 meter into lake Morskie Oko.
There are several other waterfalls in the area. I think Wielka Siklawa is one of the more known waterfalls in Poland.
