Backpacking in Lake Klönthal
👌 Worth visitinghike ranked #13
By Johan Kruseman 🇳🇱 | Updated June 1, 2026

Most guides gloss over this, but Lake Klönthal isn’t the tranquil, crowd-free escape you might expect from the filtered photos—on a sunny weekend, the lakeshore feels more like a Swiss beach party than a remote alpine retreat. Tucked in the Glarus Alps, just an hour and a half from Zurich by train and bus, Klöntalersee is almost suspiciously accessible for how wild it looks. The hike itself is a loop that hugs the water, hemmed in by sheer limestone walls and thick forest, with the kind of teal water that makes you double-take. It’s not a thigh-burner—more of a rolling stroll than a summit slog—but the path can get muddy and slick, especially after rain. You’ll dodge picnickers and grill smoke, but if you push past the main beaches, the crowds thin and the silence returns. Compared to the more famous Swiss lakes, Klönthal trades grandeur for intimacy and immediacy. I’ve ended sweaty hikes here with my boots off, feet in the glacial water, and a cheap beer from the kiosk—worth every step, even with the occasional boom box in the background.

Ranked #13 hike in Switzerland
What makes it a must-see hike

Lake Klönthal pulls backpackers in with a rare combo: a trail that demands just enough grit to feel earned but never drags you into exhaustion. The path hugs the lake’s edge, delivering a steady stream of jaw-dropping views—crystal-clear water reflecting jagged peaks, the scent of pine thick in the air, and the occasional splash of a trout breaking the surface. It’s the kind of scenery that rewards every step without making you beg for a break.

Public transport access here is a game-changer. A train or bus drops you close enough to start fresh, no car needed, no fuss. That means you can slot this hike neatly into a longer Swiss itinerary without losing time or money. Speaking of money, the trail is free to roam—no pricey permits or guided tours required. You’re in control.

💡 HighlightsKey sights and experiences for travelers

1. The North Shore Trail: Water, Rock, and Wildflowers
The north shore of Lake Klönthal is a living postcard, but don’t expect a gentle stroll. The trail hugs the water’s edge, sometimes squeezing you between sheer limestone and the lake’s glassy surface. In spring and early summer, wildflowers explode in color—alpine roses, gentians, and the occasional stubborn edelweiss. The path is uneven, roots and stones underfoot, and you’ll earn every meter. But then you round a bend and the Glarus Alps punch into view, their snowy crowns mirrored in the lake. It’s the kind of symmetry that makes you stop, sweat cooling on your back, and just stare. This is the stretch where you’ll see locals swimming, grilling sausages, or just soaking up the sun—proof that the Swiss know how to savor a landscape.

This is the stretch where you’ll see locals swimming, grilling sausages, or just soaking up the sun—proof that the Swiss know how to savor a landscape.





2. Chlüstalp: The Soundtrack of Cowbells
Push past the lake’s far end and climb toward Chlüstalp, a high meadow that feels like a set from a Swiss film—except it’s real, and you’re in it. The ascent is a leg-burner, zigzagging through spruce and larch, but the reward is a rolling pasture dotted with cows and their melodic bells. The air smells of grass and woodsmoke. If you’re lucky, you’ll catch a farmer selling fresh Alpkäse (mountain cheese) from a wooden hut. This is where the human and natural worlds blend: the clang of bells, the distant echo of a waterfall, and the taste of cheese that’s traveled zero kilometers. It’s not just scenic; it’s alive.





3. The Platten: Cliffside Drama
If you crave a shot of adrenaline, detour to the Platten, a rocky outcrop that juts above the lake’s southern rim. The trail narrows, the drop sharpens, and suddenly you’re perched above a turquoise abyss. The wind here is a force, sometimes howling, sometimes whispering secrets from the peaks. You’ll spot paragliders launching themselves into the void, their canopies bright against the sky. The view is pure drama: lake, forest, and the serrated teeth of the Glärnisch massif. This is my personal favorite—nothing else on the circuit makes you feel quite so small and so alive at the same time.





4. The Klöntal Dam: Engineering Meets Alpine Majesty
At the lake’s western end, the Klöntal dam stands as a monument to Swiss precision. It’s not just a slab of concrete; it’s a vantage point. Walk across and you get a panoramic sweep of the entire valley, the water shimmering below, the mountains crowding the horizon. The dam’s scale is humbling, but it’s the contrast—the rawness of nature against the clean lines of human effort—that sticks with you. This is where you realize the Swiss don’t just live with their landscape; they shape it, respect it, and invite you to do the same.

🌤️ When to go?Seasonal considerations and timing


  • Weather: Late spring through early autumn—May to September—offers the most reliable weather. Snow melts by May, clearing trails, while October onward risks early snow and slick paths. Summer months bring stable, dry conditions but occasional afternoon thunderstorms demand vigilance.

  • Temperature: Daytime highs range from 15°C to 25°C (59°F to 77°F) in summer, perfect for hiking without overheating. Nights can dip to 5°C (41°F), so pack layers. Shoulder months like May and September are cooler, hovering around 10°C to 18°C (50°F to 64°F), requiring warmer gear but fewer crowds.

  • Daylight Hours: Peak summer (June and July) stretches daylight to 15-16 hours, giving you long, flexible hiking windows. By September, daylight shrinks to about 12 hours, so start early to avoid hiking in the dark.

  • Crowds: July and August draw the most visitors, especially weekends. Trails can feel busy, which chips away at solitude. May, June, and September offer quieter paths and a more intimate connection with the landscape.

  • Seasonal Activities: Summer opens up swimming and boating on Lake Klönthal, adding a refreshing reward after the hike. Autumn colors start in late September, painting the forest in fiery hues but bring cooler temps and shorter days.

  • Price Fluctuations: Accommodation and transport costs peak in July and August. Booking early is crucial. Shoulder seasons like May and September often offer better deals and more availability, making the timing easier on your wallet.




Pro-tip: Aim for late June or early September—sweet spot for warm days, manageable crowds, and wallet-friendly rates. You’ll hit that perfect balance where the trail tests you just enough before rewarding you with quiet lakeside moments.

Difficulty: Moderate. The trail rolls with gentle ascents and descents, nothing too steep but enough to keep your heart pumping. It’s accessible for most hikers with decent fitness, but watch your footing on some rocky or root-strewn sections.

Starting Point: The hike kicks off in the village of Glarus Süd, specifically at the Klöntal valley entrance near the Klöntalersee parking area. Public transport is straightforward: take the train to Glarus station, then hop on a local bus (PostAuto) heading toward Klöntal. The bus drops you close to the trailhead, making it easy to ditch the car and dive right in.

Major Landmarks:
  • Klöntalersee: The shimmering alpine lake itself is the centerpiece, its turquoise waters framed by steep cliffs and forested slopes.
  • Chäserrugg Viewpoints: Several spots along the trail offer sweeping views of the Chäserrugg mountain peaks, perfect for a breather and a photo op.
  • Wildlife Observation Points: Keep an eye out near the quieter stretches for deer tracks and the occasional marmot scurrying through the underbrush.

Terrain and Scenery: The path hugs the lake’s edge, weaving through mixed forest and open meadows. You’ll cross wooden bridges over crystal-clear streams and skirt rocky outcrops that jut into the water. The trail surface varies from packed dirt to gravel, with some mossy patches under towering firs and spruces. The air carries a fresh pine scent, mingled with the cool mist rising off the lake in the morning.

Vegetation: Expect dense coniferous forests dominated by spruce and fir, interspersed with patches of wildflowers in summer—edelweiss, gentians, and alpine asters. Lower slopes show clusters of beech and maple, their leaves turning fiery in autumn.

Wildlife: The area teems with alpine fauna. You’ll likely spot chamois bounding on the cliffs, hear the sharp calls of alpine choughs overhead, and maybe catch a glimpse of a red fox slipping through the undergrowth. Birdwatchers will appreciate the variety of woodpeckers and warblers that inhabit the forest.

This trail isn’t just a walk; it’s a pulse-quickening dance with nature where every step earns a fresh vista or a quiet wildlife encounter. The payoff hits when you pause on a rocky shore, the lake’s chill breeze on your face, and realize the effort carved out this perfect slice of alpine calm just for you.
⚠️ Hiking info can sometimes be outdated or inaccurate. Before you hit the trail, check the latest conditions with locals. If you do spot anything that's off, I'd love to hear from you, so I can update it for fellow travelers.

Lake Klönthal’s trails are straightforward but demand respect for the Swiss alpine mood swings.
