We followed the day trip go and back at the same route from Blato Valley to the Triglav Lakes Mountain Hut.

We passed three mountain huts and had a break and meal at Koča na Planini pri Jezeru and Triglav Lakes Mountain Hut (Koča pri Triglavskih jezerih).

The route detailed in above link, was quite easy and enjoyable, except
one part, on the way back, we decided to try different route through Štapce
pass was quite steep and dangerous, especially since I missed to see
the stairs climbing to the correct route, I took the wrong route
climbing up through almost-straight mountain wall.
