If you’re planning a road trip through Bern, a hiking adventure in Gstaad, or simply a scenic drive through the Alpine valleys, Arnendam is the kind of “secret spot” that adds depth to your itinerary and makes for unforgettable photos.
About Arnendam
Location & Specs
- Coordinates: 46.395041 N, 7.220463 E

Arnendam is a gravity dam built to regulate the flow of water from the surrounding alpine catchments. While the exact construction year isn’t widely publicised, its design follows the classic Swiss approach of blending functionality with minimal environmental impact. The dam’s concrete façade blends into the rocky terrain, and its relatively low height means it doesn’t dominate the landscape—rather, it complements the natural beauty of the region.
Why It Matters
Switzerland relies heavily on hydro‑electric power, and dams like Arnendam play a crucial role in storing water for seasonal electricity generation, flood control, and irrigation. Though small compared with the massive Alpine reservoirs, Arnendam showcases the country’s commitment to sustainable water management in high‑altitude environments. For travelers interested in engineering, the dam offers a tangible example of how Swiss ingenuity harnesses nature without compromising the pristine Alpine scenery.
How to Get There
By Car
The most flexible way to reach Arnendam is by renting a car in Bern or Gstaad and following these simple directions:
- From Bern: Take the A12 highway toward Thun, then switch to the A6 heading east to Spiez. From Spiez, follow the road signs for Gstaad (approx. 70 km).
- From Gstaad: Follow the Gstaad‑Lenk road (Route 9) northward for about 12 km. Look for the turn‑off sign for Arnendam near the small settlement of Lauenen.
The final stretch is a well‑marked alpine road, with parking available in a small lot just a few metres from the dam’s viewing platform.

| Gstaad | Regional train to Lauenen (SBB) | 15 min | None | Lauenen (closest station) |
From Lauenen, a local bus (PostBus line 165) runs hourly to the Arnendam stop, or you can enjoy a short 2‑km hike along a well‑signed trail.
By Bike or Hike
For the adventurous, the Bernese Oberland offers a network of marked mountain bike routes. The trail from Gstaad to Arnendam is rated moderate (≈ 8 km, 400 m elevation gain) and provides spectacular vistas of the surrounding peaks.
Best Time to Visit
| Season | Highlights | Weather Tips |
|---|---|---|
| Spring (April–June) | Snow melt fills the reservoir, creating dramatic waterfalls and vibrant wildflowers. | Pack waterproof layers; afternoon showers are common. |
| Summer (July–August) | Warm days (15‑25 °C) make the dam’s viewing platform perfect for picnics. | Sun protection and plenty of water are essential. |
| Autumn (September–October) | Golden larch and pine forests; the water takes on a deep turquoise hue. | Cooler evenings; bring a wind‑proof jacket. |
| Winter (November–March) | The dam is often dusted with snow, offering a peaceful, almost mystical atmosphere. | Roads may be icy; check local conditions and consider a 4‑WD vehicle. |
Peak visitation tends to be in July and August, so if you prefer solitude, aim for early June or late September.
What to Expect
When you arrive at Arnendam, you’ll first notice the quiet efficiency of the structure. A short, paved walkway leads to a modest viewing platform that offers panoramic sightlines of the dam, the turquoise reservoir, and the surrounding Alpine peaks.
- Photography: The dam’s clean lines juxtaposed against the rugged terrain make for striking compositions, especially at sunrise when the light paints the water gold.
- Educational Insight: Small informational panels explain the dam’s purpose, the basics of hydro‑electric power, and the local flora and fauna.
- Recreational Activities: While swimming is prohibited for safety, the reservoir’s calm surface is ideal for kayaking and stand‑up paddleboarding during the summer months. Rental services are available in nearby Gstaad.
- Nature Walks: Several marked trails branch out from the parking area, ranging from easy loops (1 km) to more demanding hikes that climb toward the Weisshorn ridge.
Overall, Arnendam offers a low‑key, contemplative experience—perfect for travelers who want to step away from crowded tourist sites and connect with Switzerland’s engineering heritage and natural beauty.
