Towering above Lake Thun in the Bernese Oberland, the Niesen (2,362m) is Switzerland’s most geometrically stunning mountain—a near-flawless natural pyramid that has captivated artists, hikers, and engineers for centuries. Often called the “Swiss Pyramid,” – one of Switzerland’s most scenic spots – its symmetrical triangular silhouette, best seen from Thun or Spiez, is so precise it seems sculpted by hand. This iconic shape, formed by glacial erosion and its isolated position, casts a dramatic pyramidal shadow onto Lake Thun each autumn, a phenomenon celebrated in local lore and modernist art. But the Niesen isn’t just a visual marvel; it’s also home to the world’s longest staircase—a staggering 11,674-step ascent used just once a year for a legendary race—and a 1910 funicular that glides visitors to panoramic heights.
A Mountain of Art and Engineering
The Niesen’s geometric perfection has inspired Swiss masters like Ferdinand Hodler and Paul Klee, who immortalized its form in paintings emphasizing its stark contrast with Lake Thun’s blue waters. Today, the summit remains a cultural hub, hosting summer concerts and open-air theater against alpine vistas. Reaching the top is half the adventure: the Niesenbahn funicular, a vintage red-and-white carriage with wooden benches, climbs 1,669 vertical meters in just 30 minutes, passing meadows and cliffs. At the summit, the Berghaus Niesen Kulm—a historic 1856 lodge—offers fondue with 360° views spanning the Eiger, Jungfrau, and two lakes.
The Staircase Challenge
For thrill-seekers, the Niesen’s hidden gem is its Guinness-record staircase, tracing the funicular’s route. Closed year-round except for the annual Niesen Stairway Run, this grueling race sees athletes climb the equivalent of three Empire State Buildings in under two hours. While most visitors opt for the funicular, hikers can tackle trails from Mülenen or Frutigen, rewarded with wild gentian flowers and fewer crowds. Families love the “Niesendörfli” playground and fox-themed storytelling rides, while photographers chase the pyramid’s shadow on Lake Thun in October.
Niesen Sunsets and Sup & Sip Magic
The Niesen is particularly breathtaking when viewed from Neuhaus, one of Interlaken best summer swimming spots, a tranquil spot on Lake Thun’s shores near Interlaken. During sunset, the pyramid’s silhouette is bathed in golden light, creating a truly magical scene. For an even more enchanting experience, consider a Sunset SUP & SIP adventure. Paddle across the lake on a stand-up paddleboard as the sun dips below the horizon, sipping wine or a refreshing drink while taking in the Niesen’s majestic form. This unique combination of nature, relaxation, and scenic beauty makes for an unforgettable evening. As you glide across the lake, the Niesen rises above you, its pyramid shape reflected perfectly in the calm waters, creating a moment of serene harmony between nature and adventure.
Why Visit from Interlaken?
Just 25 minutes by train, the Niesen is an easy day trip from Interlaken. Whether you ride the funicular at sunset, explore its art history, or dream of conquering the staircase, this “Swiss Pyramid” delivers alpine magic without the altitude extremes of its famous neighbors. As locals say: “Ufe Niese cho gniesse!” (Up to the Niesen to enjoy!).
