There’s something deeply grounding about train travel—the soft hum of the tracks, the shifting scenery through wide windows, and the calm that comes from watching the world pass by without rushing through it. For slow travelers, eco-conscious explorers, and nature lovers, train journeys across Europe offer a peaceful, low-impact way to see the continent’s most beautiful corners—without the stress of airports or the environmental impact of flying.

In this guide, we’ve handpicked some of the most spectacular, sustainable train journeys in Europe that let you immerse yourself in nature, pass through hidden villages and remote valleys, and arrive at destinations that still feel untouched. These are the kinds of journeys that let you settle in and actually see the land you're moving through—without the blur of highway signs or the stress of terminals.

1. The Glacier Express, Switzerland

Route: Zermatt to St. Moritz
Duration: ~8 hours

Often called "the world’s slowest express train," the Glacier Express is a legend—and for good reason. This route takes you deep into the heart of the Swiss Alps, winding through 91 tunnels and crossing 291 bridges, including the famous Landwasser Viaduct. It’s one of the best ways to experience Switzerland’s dramatic alpine scenery, with views of snow-dusted peaks, green valleys, and sleepy mountain villages.

The Glacier Express runs primarily on hydropower, part of Switzerland’s renewable energy rail network. Choosing this train over flying between regions drastically reduces your carbon footprint.

Trippers Terminal Tip: Sit on the right side of the train when heading east for panoramic views of the Rhine Gorge (also known as Switzerland’s Grand Canyon).

Where to Stay: The Kulm Hotel in St. Moritz blends luxury with sustainability—it runs on renewable energy and supports local conservation projects.

2. The Bernina Express, Switzerland to Italy

Route: Chur, Switzerland to Tirano, Italy
Duration: ~4 hours

One of Europe’s most stunning transnational routes, the Bernina Express is a UNESCO-listed journey that links glaciers to palm trees. You’ll pass by alpine lakes, impressive viaducts like the Brusio spiral, and quiet meadows dotted with wooden chalets. The route feels like a moving postcard—especially in spring or early autumn when the colors really come alive. (including the dramatic Brusio spiral viaduct), and lush meadows, all from the comfort of panoramic windows. Spring and early autumn are especially magical, with wildflowers or golden foliage lining the way.

Like the Glacier Express, this route is powered by hydropower and maintained with sustainability in mind.

Trippers Terminal Tip: Break your journey in Poschiavo for a lakeside stroll and local gelato before continuing on to Tirano.

Where to Stay: We recommend Hotel Bernina in Tirano - a cozy, eco-conscious stay with easy access to wine country and local trails.

3. The West Highland Line, Scotland

Route: Glasgow to Mallaig
Duration: ~5.5 hours

This is Scotland at its most cinematic. The West Highland Line whisks you from the city into raw, rugged wilderness—think misty lochs, Highland cattle, and peaks that roll into the clouds. It’s also home to the famous Glenfinnan Viaduct, featured in the Harry Potter films. But beyond the movie magic, it’s a deeply tranquil route that feels worlds away from the modern rush.

Scotland’s rail network is committed to carbon neutrality, and this line encourages car-free exploration of protected wildlands.

Trippers Terminal Tip: Hop off at Arisaig—the UK’s westernmost station—for a quiet beach walk and sea views.

Where to Stay: Book a night at the eco-friendly Mallaig Backpackers Lodge or stay in a rustic B&B that uses local produce and energy-efficient systems.

4. The Cinque Terre Express, Italy

Route: La Spezia to Levanto (stopping at all 5 Cinque Terre villages)
Duration: ~30 minutes (entire line)

Short, sweet, and incredibly scenic—the Cinque Terre Express is the most sustainable way to explore this famous stretch of Italian coastline. Instead of driving (which is discouraged), you can hop between the five fishing villages by train. You’ll glide past cliffs, terraced vineyards, and the sparkling Mediterranean, all while skipping the traffic.

The train supports the Cinque Terre National Park’s green tourism efforts. Rail travel reduces traffic congestion and erosion damage in this fragile region.

Trippers Terminal Tip: Travel early in the morning or late afternoon for fewer crowds and golden light perfect for photography.

Where to Stay: La Casa di Maro in Riomaggiore is a boutique stay with solar power, sea views, and a strong focus on sustainability.

5. Porto to Pinhão, Portugal

Route: Porto to Pinhão via Douro Valley
Duration: ~2.5 hours

This route winds through one of Europe’s oldest and most beautiful wine regions, the Douro Valley. Sit on the right side of the train for views of terraced vineyards rolling into the Douro River. In spring and autumn, the landscape glows with either fresh greens or harvest golds. You’ll pass through small river towns where life revolves around wine and the land. Worth noting that Portugal’s rail system has committed to lowering emissions, and the Douro Valley region champions sustainable viticulture.

Trippers Terminal Tip: Bring a picnic from Mercado do Bolhão in Porto and enjoy it on the riverbank in Pinhão.

Where to Stay: The Vintage House Hotel in Pinhão blends timeless charm with green practices and overlooks the river from its garden terrace.
