On the Pl. below Mišelj vrh from the direction of Veliko p. you keep only to the left at the last collapsed shepherd hut.
The path is nicely trodden and easy, no protection needed anywhere.
Otherwise, you have Jezerski Stog in view from Vodnik all the time (if there is no fog, of course).
The other side of Jezerski saddle is Pl. Jezerce (drinking water), 20 min descent from the saddle. From Pl. Jezerce, after half an hour of moderate walking, you reach Pl. Krstenica.
If you wanted to go to Prevalski Stog by chance, you can also hop to Adam and Eva.
In good weather, the views from all mentioned peaks are really magnificent, especially towards Veliko polje with Tosc and Vernar in the background and, of course, Triglav, Rjavina, Mišelj vrh, Škednjevec, Debeli vrh...
Good luck!
