Switzerland by rail: a 7-day route from Lucerne without a hire car

Five named trains, six regions, zero rental cars. That’s the pitch, and on paper it looks like a brochure fantasy — but every leg below runs on the regular Swiss timetable, and you can book most of it the week before you travel. The two things that make or break the trip aren’t the trains themselves; they’re the seat reservations (paid separately, even with a pass) and accepting that some connections eat half a day and that’s fine, because the connection is the point.

This route starts and effectively ends in the Lucerne region, loops through the Interlaken lakes, over the Alps to Montreux, up to Zermatt, across the passes to St. Moritz, and down into Lugano on the Italian side of the Alps. If you want the full loop closed, the last section explains how to add an eighth day and ride back to Lucerne on the Gotthard Panorama Express.

Why base the whole trip on the Swiss Travel Pass

An 8-day Swiss Travel Pass, second class, runs somewhere in the CHF 400–450 range for an adult — steep on its own, but it bundles unlimited travel on SBB regional and InterCity trains, city buses and trams in every town on this route, and the standard Lake Lucerne boats. What it does not cover is the seat reservation surcharge on the Glacier Express and Bernina Express, which you pay on top regardless. Read the full breakdown in the Swiss Travel Pass guide before buying — for a trip this dense it usually pays for itself, but do the maths on your actual dates rather than assuming it.

Leg	Train	Approx. duration	Reservation required
Lucerne → Interlaken Ost	Luzern–Interlaken Express	1h 50	No
Interlaken → Montreux	GoldenPass Line/Express	3h–3h 15	Peak-season carriages only
Montreux → Zermatt	Regional via Visp	2h 30–3h	No
Zermatt → St. Moritz	Glacier Express	7h 50	Yes, always
St. Moritz → Lugano	Bernina Express + connecting bus	4h 30–5h	Yes, train portion

Day 1: settling into Lucerne

Land, put your bags down, and don’t try to do anything ambitious on the first day — jet lag and a week of packed transfers ahead make that a mistake. Walk the Old Town, cross the Chapel Bridge, and take an hour at the Lion Monument, which is smaller and quieter than photos suggest but worth the ten-minute walk from the centre. Activate your Swiss Travel Pass at any SBB counter or through the app the evening before your first travel day, not on the day itself — activation is instant but queues at Lucerne station in the morning are not.

If you have energy left, a half-day up the Rigi is a gentle way to test the cogwheel-railway rhythm you’ll be living with all week — book a round trip up the Rigi by cogwheel railway and boat and you’ll be back in town for dinner. Skip it if you’d rather save your legs for Mount Pilatus on a future trip — this itinerary doesn’t have room for both, and that’s deliberate.

Day 2: Lucerne to Interlaken

The Luzern–Interlaken Express is the mildest scenic train on this trip and the best warm-up: no reservation, standard second-class carriages, and a route over the Brünig Pass that climbs through farmland and pine forest rather than anything alpine-dramatic. The whole ride is under two hours, so you’ll be in Interlaken by late morning with the rest of the day free. Interlaken itself is a transit town more than a destination — most travellers use it as a base for the mountains around it — so spend the afternoon on the Harder Kulm funicular for the view over both lakes, or just walk the shoreline. Save your energy: tomorrow is a long day.

Day 3: the Jungfraujoch, in full

This is a dedicated day, not an add-on — the round trip to Europe’s highest railway station and back takes most of a full day once you account for the multiple cogwheel changes at Lauterbrunnen and Kleine Scheidegg. Go with a guided day trip up to the Jungfraujoch rather than assembling the connections yourself on your first attempt — the timing windows for the final ascent are tight and a missed connection here costs hours, not minutes. Check the Jungfraujoch guide for the current weather-visibility odds before you commit; on a cloudy day the summit terrace is a white-out and the ticket price stops making sense.

Day 4: Interlaken to Montreux on the GoldenPass

This is the day most people remember. The GoldenPass Line — now largely run as the through GoldenPass Express with a change of gauge handled for you at Zweisimmen — climbs out of the Bernese Oberland, past Gstaad, and drops down toward Lake Geneva with the vineyard terraces of Lavaux visible on the final approach. Budget three hours for the ride itself and check the GoldenPass Line guide for whether your specific departure needs a reservation — panoramic carriages in July and August often sell out a week ahead.

Arrive in Montreux with the afternoon still open and walk the lakefront promenade to Château de Chillon, the moated castle that’s actually worth the entry fee, unlike a few over-marketed castles elsewhere in the country. If the weather’s clear and you want altitude before you leave the region, a day trip up to Glacier 3000 above Montreux is a fair use of a spare afternoon, though it does mean skipping some of the town itself.

Day 5: on to Zermatt

There’s no single named scenic train between Montreux and Zermatt — you connect through Visp on regular InterCity and regional services, roughly two and a half to three hours depending on the change. It’s a less photogenic leg than the days either side of it, which is fine; treat it as recovery time. Zermatt itself is car-free by law, so once you step off the train at the village station you’re walking or taking an electric taxi for the rest of your stay.

Spend the afternoon getting your first look at the Matterhorn from the village, then ride up with a cogwheel journey up to the Gornergrat for the classic head-on view — it’s a different angle and a different train system from the Klein Matterhorn cable car, and cheaper. Don’t try to do both viewpoints in one afternoon; pick one and actually enjoy it rather than rushing between two ticket queues.

Day 6: the Glacier Express to St. Moritz

Nearly eight hours end to end, and that’s the entire point of the day — the Glacier Express isn’t transport so much as a slow-motion cross-section of the Alps, crossing the Oberalp Pass and the Landwasser Viaduct with a dining-car lunch service included in most reservation tiers. Reserve seats weeks ahead for summer departures; this train sells out further in advance than almost anything else on this itinerary. Read the Glacier Express guide for which side of the carriage to sit on for the best light, since it genuinely matters and the answer changes depending on your departure time.

You’ll arrive in St. Moritz in the early evening with just enough daylight for a walk along the lake before dinner — don’t plan anything more ambitious for this day.

Day 7: the Bernina Express to Lugano

The Bernina Express is shorter than the Glacier Express but climbs higher relative to its length, crossing the Bernina Pass in daylight with no tunnel to hide the view, then dropping through the Val Poschiavo’s stacked spiral viaducts down to Tirano on the Italian border. From Tirano, the onward connection to Lugano is a coach, not a train — factor that into your expectations, since it’s a comfortable bus but not another scenic railway. Total journey time is four and a half to five hours; check the Bernina Express guide for current timetables, since the Tirano bus connection changes more often than the rail schedule either side of it.

Lugano itself, once you arrive, feels more Italian than Swiss — palm trees, a lakefront piazza, and noticeably better coffee than anywhere else on this trip. Spend the evening here; it’s a fair place to end a week that’s otherwise been almost entirely about motion.

Closing the loop back to Lucerne

If you want to finish where you started rather than flying out from Lugano or Milan, add an eighth day and take the Gotthard Panorama Express — a lake boat from Lucerne to Flüelen paired with a train over the Gotthard, run only from spring through autumn. Don’t try to stack it onto the same day as the Bernina Express; the connection isn’t realistic and you’ll spend the whole day watching timetables instead of scenery.

If the Gotthard Panorama Express isn’t running when you travel, or you’d rather save the day, the plain InterCity route back to Lucerne through the Gotthard base tunnel takes under three hours — check getting around Lucerne and the wider Swiss trains explained guide for how that connection fits with the rest of the network.

FAQ: planning a rail-only week across Switzerland

Do I need the Swiss Travel Pass for this route?

You don’t strictly need it — every leg can be bought as a single ticket — but with six regions in seven days the pass usually comes out cheaper, and it also covers city buses, the Lucerne lake boats and museum entry along the way. Price it against your actual dates before assuming it wins; short summer trips with few detours sometimes don’t clear the break-even point.

Do I need to reserve seats on every scenic train?

The Glacier Express and Bernina Express require a paid seat reservation even if you hold a valid pass, typically CHF 20–50 per person depending on the train and season. The Luzern–Interlaken Express and most GoldenPass connections don’t require reservation, though the panoramic GoldenPass Express carriages do in peak months.

Can this itinerary be done in fewer than 7 days?

Five or six days is possible if you drop either the Jungfraujoch day trip from Interlaken or the Lugano leg and fly home from Zurich after St. Moritz instead. Cutting further than that turns most days into transfer days with no time to actually see anything.

Which direction should I travel, Lucerne to Lugano or the reverse?

Either direction works logistically, but starting in Lucerne front-loads the Jungfraujoch day trip while the weather forecast is still fresh, and it saves the Bernina Express — arguably the most dramatic single ride — for the final full day rather than the first, when jet lag can dull it.

What happens if a mountain lift is closed for maintenance?

Cable cars and cogwheel railways in this region routinely close for two to four weeks in spring and again in autumn for annual inspection. This itinerary doesn’t depend on any single summit staying open — check the Jungfraujoch and Gornergrat status pages before booking rather than after.

How do I get back to Lucerne from Lugano at the end?

The direct return is the Gotthard Panorama Express — a lake boat from Lucerne to Flüelen paired with a train over the Gotthard, run only from spring to autumn — but doing it the same day as the Bernina Express is not realistic; treat it as a genuine eighth day, or take the plain Gotthard base tunnel train back to Lucerne in under three hours instead.
