About Diga del Narèt II
What Is It?
- Type: Concrete gravity dam 🏗️
- Location: Airolo, Canton Ticino, Switzerland
- Coordinates: 46.478420 N, 8.575335 E
- Height: 45 m (approximately 148 ft)

Built as part of a cascade of water‑management structures in the upper Ticino River basin, Diga del Narèt II serves primarily for hydro‑electric power generation and water regulation. Its sleek concrete façade blends seamlessly with the surrounding granite cliffs, while the reservoir behind it mirrors the dramatic sky and nearby peaks.
A Brief History
The dam’s construction dates back to the late 20th century, a period when Switzerland intensified its investment in renewable energy infrastructure. While exact completion dates are scarce in public records, Diga del Narèt II was erected to complement the older Diga del Narèt I, creating a staged series of water retention points that optimize flow for downstream power stations. The project reflects the Swiss commitment to sustainable energy, harnessing the relentless Alpine runoff without compromising the region’s ecological balance.
Why It Matters
- Renewable Energy: Contributes to Ticino’s hydro‑electric grid, a cornerstone of Swiss clean‑energy policy.
- Engineering Showcase: Demonstrates the precision and durability of Swiss dam construction in challenging mountain terrain.
- Scenic Value: Offers a tranquil spot where the engineered meets the natural, perfect for contemplation and photography.

How to Get There
By Train
Airolo is a major stop on the Gotthard railway line, connecting northern Switzerland (Zurich, Lucerne) with the Italian border (Chiasso, Milan). From Zurich Hauptbahnhof, board an InterCity (IC) or regional train to Airolo (≈ 2 hours). The station sits at the foot of the valley, just a short walk from the dam’s parking area.
By Car
If you prefer driving, the A2 motorway (the Gotthard route) brings you directly to Airolo. Exit at the Airolo toll plaza, follow signs for Strada Statale 2 toward the dam. The journey offers spectacular Alpine panoramas, especially when crossing the Gotthard Tunnel. Parking is limited but free near the dam’s visitor viewpoint.
By Bus / Shuttle
During summer months, local bus line Ticino Bus 1 runs a limited service from Airolo town centre to the dam’s trailhead. Check the Ticino Mobil timetable for exact times.
Walking / Hiking
For the adventurous, the Narèt Trail starts at the Airolo train station and winds up to the dam in roughly 45 minutes (≈ 3 km, moderate elevation gain). The path is well‑marked, suitable for most fitness levels, and rewards you with panoramic views of the reservoir and surrounding peaks.
Best Time to Visit
| Season | Highlights | Visitor Tips |
|---|---|---|
| Spring (April‑June) | Snow melt swells the reservoir, creating dramatic waterfalls and lush alpine flora. | Wear waterproof shoes; early mornings have fewer crowds. |
| Summer (July‑September) | Warm, sunny days perfect for photography, picnics, and longer hikes to nearby waterfalls. | Bring sunscreen and a hat; afternoon thunderstorms are possible. |
| Autumn (October‑November) | Golden foliage adds a warm hue to the dam’s concrete, and the water reflects stunning sunset colors. | Dress in layers; daylight hours shorten. |
| Winter (December‑March) | The dam is often dusted with snow, offering a serene, almost mystical atmosphere. | Check road conditions; some trails may be closed due to snow. |
Overall, late spring to early autumn provides the most accessible conditions and the richest visual palette for visitors.
What to Expect
Arriving at Diga del Narèt II, you’ll first notice the crisp Alpine air and the quiet hush that only high‑altitude locations can deliver. The dam itself is an impressive 45 m wall of concrete, but the real star is the reservoir that stretches upstream, its surface a glassy mirror for the surrounding peaks.
- Scenic Viewpoint: A short, well‑maintained platform offers unobstructed views of the dam’s spillway and the river coursing below. Ideal for sunrise or sunset shots.
- Educational Plaques: Small information boards explain the dam’s purpose, hydro‑electric process, and environmental safeguards.
- Wildlife: Expect to see alpine marmots, chamois, and a variety of bird species (e.g., golden eagles) soaring overhead.
- Peaceful Atmosphere: Unlike crowded tourist hotspots, the area remains relatively tranquil, allowing you to soak in the landscape at your own pace.
While there are no cafés or souvenir shops on site, the nearby village of Airolo (just a 10‑minute walk) offers a modest selection of restaurants serving traditional Ticinese cuisine—think polenta, risotto, and locally sourced cheeses.

Travel Tips
| Tip | Why It Matters |
|---|---|
| Start Early | Morning light enhances the dam’s reflections and reduces the chance of crowds. |
| Dress in Layers | Alpine weather shifts quickly; a breathable base layer, insulating mid‑layer, and wind‑proof outer layer keep you comfortable. |
| Carry a Small First‑Aid Kit | Trails can be rocky; a few band‑aids and antiseptic wipes are handy. |
| Bring a Binocular | Spotting distant wildlife or distant peaks adds to the experience. |
| Respect the Environment | Stay on marked paths, avoid littering, and follow any signage about water safety. |
| Check Transport Schedules | Train and bus services may be reduced in winter; confirm times in advance. |
| Use a Portable Charger | Cell service can be spotty; a charged power bank ensures you can capture photos and navigate with GPS. |
| Currency | While Switzerland uses the Swiss franc (CHF), many Alpine shops accept credit cards. Have a small cash reserve for rural vendors. |
| Language | Italian is the primary language in Ticino; basic greetings (“Buongiorno”, “Grazie”) go a long way. |
| Photography | A polarizing filter reduces glare on the water surface; a wide‑angle lens captures the dam’s scale against the mountains. |
