Klöntalersee to Gumensattel: Glarus
I’m not going to sugarcoat it: this one will make you suffer.
Klöntalersee is easily, easily, one of the most beautiful lakes in Switzerland. Seeing it from above, a fjord-like turquoise lake surrounded by sheer mountains, is an absolute treat. Unfortunately, it is not easy to get there. When I read about this trail, it was referred to as an “insider tip,” because you’ll likely see few other hikers. Now I know the real reason: it’s a sufferfest. But a beautiful one!
The trail from Rhodannenberg is straight up the mountainside, covering over 1300 vertical meters in about 5 kilometers (that’s about 4200 feet in 3 miles for my US friends) - making it one of the steepest hikes I’ve done so far. The path itself is narrow, unmarked, and overgrown. I wore shorts, and regretted every step through the tall and itchy grass. The uphill is relentless. There are a few, very short flat areas, but for the most part, you’ll be gaining elevation until the highest point of Gumensattel. The descent isn’t any easier. It starts gradually, but then very steeply descends about 1000 meters back down to the lake shore.
For all this, though, you are rewarded with near-constant views of the Vorderer Glärnisch mountain chain and the bright turquoise Klöntalersee. The only way you’ll be able to see the lake from above is by foot. It’s not enough to completely forget about all the pain and suffering, but it is enough to make it worth your time.

A few tips:
Don’t underestimate the elevation gain. I love steep hikes more than most, and I struggled on this one.
Consider wearing hiking pants (even if it is hot!), especially if you have sensitive skin. The trail isn’t heavily used, so it’s very narrow, and in most sections on the ascent, overgrown with grass and plants. My legs are still itching two days later.
Gumensattel is the highest point, but I’d recommend descending a little bit down the other side, where you’ll find some nicer areas for a lunch break.
Remember to bring a swimsuit! A swim in the lake post-hike is a must.
