It is located in the lower part of the Fratarica waterfall area above the Ihta waterfall.

After descending to the Cathedral basin we find ourselves in a magnificent arched hall with a gothic window with a view opening onto the rock walls of Loške stene.
Below roars the 20-metre Cathedral waterfall, ending in a magical lake.

At the mouth of the waterfall there is a large rock wedged in, past which life flows.

Above the Ihta waterfall, the path leads to the left bank and the pastures of Ubiceva frata clearing (name of the homestead), where the name Fratarica comes from.

The path continues upwards above a magnificient basin, where it levels a little and descends to the Cathedral.

To descend to the Cathedral a static rope is recommended.

One can experience the mystique of the window and the waterfall with a guide for canyoning.
