Uetliberg Layover: Zurich's Mountain by Train
Part of the full Zurich Layover: Old Town and Lake From ZRH
Uetliberg is the wooded ridge along Zurich’s southwestern edge, 871 metres up, with free viewpoints over the whole city and the lake, a lookout tower charging CHF 5 for another 72 metres, and a six-kilometre ridge path laid out as a scale model of the solar system.
The lookout tower’s 178 steps above the summit
The plateau at the top already gives you the view most people come for, free and unticketed: Zurich laid out below on one side, the lake narrowing away south on the other. The tower is the upgrade. Seventy-two metres of steel lattice with switchback stairs, 178 of them, ending on an open platform that costs CHF 5, taken by card or by 1 and 2 franc coins at the barrier.
What the extra height buys is the Alps, which the trees at ground level cut into. The Uto Kulm hotel and restaurant shares the plateau, so there is somewhere to sit and a roof if the weather turns, and a television mast stands behind it.
Getting up and back is where the money actually goes rather than on the tower, and a 24-hour city card covers the fare up here, the cable car at the far end of the ridge and the rest of the local network on one purchase, which is worth the arithmetic on a day with more than a couple of journeys in it.
Autumn is the season worth planning around rather than avoiding. From October onwards Zurich spends long stretches under a temperature inversion with fog sitting on the city all day, and the ridge is high enough to be above it: from up here the fog reads as a flat white sea with the Alps standing out of it, while the city underneath sees nothing at all.
The climb from the station to the plateau is 56 metres of ascent on a forest path with no shelter, no benches wide enough to set anything beside you and nowhere at the top to leave a bag while you go up the tower.
The Planetenweg, a solar system laid along the ridge
Arnold von Rotz set this out in 1979 and it has been on the ridge ever since: six kilometres of gravel path from the summit south to Felsenegg, with the solar system modelled along it at one to a billion. A metre walked is a million kilometres covered, and the planets sit on boulders and posts at the right distances apart, each with a panel and a scaled disc.
The full walk takes about two hours and is genuinely easy: a wide forest road along the crest with almost no gradient after the first climb, and views opening on both sides. Nothing obliges you to finish it. The inner planets are bunched into the first few hundred metres, so ten minutes of walking already gets you past the Earth, and turning back costs nothing. If you do go the distance, a cable car at Felsenegg drops to Adliswil, where trains run back into the city.
The steepest standard-gauge railway in Europe climbs from the city
Trains grind up here at gradients of up to 7.9 per cent, which is the steepest anywhere on standard-gauge track in Europe that works by wheel-to-rail adhesion alone, with no rack to bite into. The line ends at 813 metres, 650 metres short of the summit and 56 below it, so the last stretch is on foot either way.
The ride is about 20 minutes end to end, running roughly every twenty minutes at weekends and less often on the full length during the week. Until 18 October 2026 there is a complication: the underground platforms at Zürich Hauptbahnhof that these trains normally use are closed for rebuilding, so services start from Zürich Selnau instead, a signposted 12-minute walk from the main station or six minutes from the Stauffacher tram stop. After that date the trains go back to leaving from the main station.
Working back to the airport from 871 metres
Allow two hours from the summit to the gate at ZRH, and more if the weather has been good enough that you walked part of the ridge. That covers the descent to the station, the ride down, the walk or tram across to Zürich Hauptbahnhof, collecting the bag and the airport leg itself.
The last part is the quick one. SBB trains cover the main station to the station under the Zurich Airport terminal in 10 to 15 minutes depending on the service, leaving about every 10 minutes, on a CHF 7.20 adult second-class single across the three ZVV zones. The mountain fare is separate and depends on which ticket you already hold.
This is the one route out of Zurich where the weather decides whether it was worth doing, so check the summit before committing five hours to it. On a clear day it is the only place near the city where you can see the Alps and the lake and the old town at once.
Frequently asked questions
Can you get up Uetliberg while the main station's lower platforms are closed?
Yes, with one extra step. From 29 April to 18 October 2026 the underground platforms at Zürich Hauptbahnhof used by the mountain trains are shut for rebuilding, and those services start and finish at Zürich Selnau instead. A signposted walkway covers the gap in about 12 minutes on foot, or a tram gets you to Stauffacher, six minutes from Selnau. After 18 October the trains run from the main station again.
Do you have to pay for the view from Uetliberg?
Not for the main one. The viewpoints on the summit plateau, looking north over Zurich and south down the lake, are open ground with no ticket. The lookout tower on top of them charges CHF 5, taken by card or by 1 and 2 franc coins, and buys you 178 steps and another 72 metres of height, which mostly adds the Alps to what you can already see.
How long does the Planet Trail take?
About two hours for the full six kilometres from Uetliberg along the ridge to Felsenegg, on a wide gravel path with no scrambling. You do not have to walk all of it: the first planets are within a few minutes of the summit, and turning back at any point is fine. From Felsenegg a cable car drops to Adliswil for the train back into the city.
Is Uetliberg realistic before a flight?
Only on a long gap. Between the ride up, the climb from the station and the trip back out to the airport, this needs about five hours to be worth doing and is uncomfortable on four. If you have less than that, the old town on the Limmat is the better call: the Grossmünster, the Fraumünster and the Lindenhof all sit inside a ten-minute walk of Zürich Hauptbahnhof.
