Rinnensee

The Rinnensee (approx. 2,648 m) is one of the most secluded alpine lakes in the Oberbergtal. The tour begins at the Oberissalm parking lot, first leads to the Franz-Senn-Hütte, and from there continues on into the high mountains. No shortcut, no crowds.

Why the Rinnensee?

Precisely because it isn’t easy to reach. The Rinnensee lies in a cirque far above the tree line, surrounded by rock and névé. Those who make it here find quiet, clear water, and a high-mountain landscape about as untouched as it gets.

Route Description

Oberissalm parking lot (1,742 m): Starting point in the Oberbergtal, marked path towards the Franz-Senn-Hütte.

Franz-Senn-Hütte (2,147 m, approx. 1.5 hrs): Staffed hut, last chance for refreshments before the long ascent.

High mountain zone (2,200–2,600 m): Long climb above the hut. The path becomes increasingly rocky and steep. Follow the markings carefully.

Rinnensee (approx. 2,648 m): After the final steep section, the high plateau with the lake opens up. Solitude, expanse, quiet.

Requirements

• Very good fitness required (long ascent beyond the Franz-Senn-Hütte)
• Sure-footedness essential in the upper terrain
• Head for heights needed on exposed sections
• No dogs – wildlife protection area and terrain too demanding
• Weather awareness: no shelter above the hut

Tips

• Early start: The route is long – start early at the Oberissalm parking lot
• Provisions: Nothing available beyond the Franz-Senn-Hütte – bring enough water and food
• Best time: July to September
• Alternative destination: Those with less time turn back at the Franz-Senn-Hütte – already worthwhile

The Rinnensee is a tour for experienced mountain hikers seeking solitude and genuine high-mountain atmosphere. You have to earn it – but you’ll be rewarded.
