Striding-out along high trails on both sides of the bucolic Justistal - you see where you’re going and where you’ve been. After a warm up following the river, forested switchbacks lead to a series of ladders bolted to the limestone cliffs up to Hohseil. It's a steep start, but you're quickly on the ridge with dramatic views of the Eiger, Mönch, and Jungfrau. Follow the ibex towards Gemmenalphorn (2061m), they seem to like this spot too.

At Gemmenalphorn, you’re looking at the long ridge of the Hardergrat-- a run for another day! From the far end of the loop, you see the length of the green valley, leading towards Thunersee. A quick drop down and then climb up again on the other side of the U-shaped valley. Airy single track flows along the exposed rock wall on a shelf just wide enough to speed onward. You'll meet some technical forest trail until reaching Underbärgli’s grassy pasture. Sloping downhill through fields and farms gives you a break from concentrating on your footing, but there’s a few technical switchbacks and a slight climb before joining the forest road and coasting back to Justistal.
