Seven Lakes Valley Hike
Free
Honest take: this hike kind of sucked, ha. The valley strings together a chain of glacial lakes (from the Black Lake up past the Double, Kidney, Green, and Brown lakes), and it was much harder than I expected. I prebooked a 6:30am taxi from Hotel Bohinj to Planina Blato, and the trail goes uphill immediately to give you a taste of what's coming. I made it to the Double Lake, but I'd thought I'd downloaded the trail map and it didn't actually work, so I got very lost. I tried to descend via Savica Waterfall, had to backtrack, and finally came down via Vogar — where I was too tired to walk the extra three minutes to the viewpoint. With no return taxi booked and almost no cell service, I walked all the way back to the lake: roughly 30 km, and my legs and feet were hating me. If you go, wear proper hiking boots (maybe even bring poles — the downhills get brutal), make sure your offline map actually works, and plan your ride back.
