Kandertal Transport: Trains, PostBuses and the Last Bus Problem

Kandertal Transport: Trains, PostBuses and the Last Bus Problem

The 16:30 PostBus pulls away from Griesalp and you are still 400 metres above it on a trail you misjudged. That is the single moment that defines transport in the Kandertal. There is no second bus. There is no taxi. There is no mobile signal to call anyone. You walk down the steepest road in Europe or you sleep on the alp. Here is exactly how to use the trains and PostBuses that do exist, and how not to get caught by the ones that do not.

Train Access: Bern, Spiez and the Lötschberg Line

The only rail route into the Kandertal is the BLS Lötschberg line from Spiez. From Bern, take the IC to Spiez (28 to 33 minutes), then change to the RE that runs 26 minutes up the valley to Kandersteg. Total journey time from Bern is 54 to 59 minutes. Full fare is roughly CHF 35 to 40.

From Zürich HB, the IC to Bern takes 56 to 61 minutes, then Bern to Spiez, then Spiez to Kandersteg. Total is 1 hour 50 minutes to 2 hours, CHF 75 to 80. From Genève, add the 1 hour 42 minute to 1 hour 50 minute IC to Bern, then the same connection: total 2 hours 36 minutes to 2 hours 49 minutes.

Kandersteg sits at 1,176 metres in the village centre, 300 metres from the Sunnbüel cable car valley station and 800 metres from the Oeschinensee gondola. Both are walkable. You do not need a car to reach any of the valley lifts from the train.

What to Download Before You Leave Spiez

Swisscom has 4G in Kandersteg village and at Oeschinensee. Gasterntal and Griesalp have zero signal. Sunrise and Salt are patchy even in the valley. Download the SBB Mobile app for tickets, load your itinerary, and download offline maps before you leave Spiez. If your phone has no data in Gasterntal, you have no way to check a timetable or call a bus company.

The PostBus Network: the Only Onward Option

Beyond the train stop, public transport in the Kandertal means PostBus. Drivers do not sell tickets on board. You pay with coins or through the SBB Mobile app before boarding. No card, no app, no ride.

Two PostBus lines matter for visitors. Line 230 runs Spiez to Kandersteg via Blausee. Line 220 runs Reichenbach im Kandertal up the Kiental valley to Griesalp. Journey time from Reichenbach to the road's end is roughly 35 minutes. The section from Pochtenalp to Griesalp requires a mandatory reservation. Call +41 58 448 06 22 the day before travel, before 16:00. Without a reservation, you do not board that section. The Griesalp road hits a 28 per cent gradient, the steepest regular PostBus route in Europe.

Gasterntal Access Without a Car

Gasterntal has no PostBus. Private cars need a day permit from the Kandersteg municipal office (CHF 15). Cars are banned from the single lane road between 10:00 and 16:00 in peak months, and the road is closed to all private traffic from 22:00 to 06:00. If you are walking, the road is open to pedestrians at all hours. The suspension bridge crosses the glacial river near the old Waldhaus hotel, and the valley is raw, quiet and entirely without mobile signal. Do not walk in after 14:00 if you need to return the same day. The road is 8 kilometres long and uphill on the way back.

The Last Bus Problem

The single biggest friction in the valley is the last PostBus departure from Griesalp and Gasterntal. Even in July and August, that bus can leave as early as 16:30. There is no taxi backup. If you are on the trail above Griesalp and you miss it, you walk down the 28 per cent gradient road or you stay overnight. The Griesalp hotel takes cash only, no card terminals. Plan every hike so that you are at the stop a quarter of an hour before the last departure. Check the SBB app the morning of your hike, because the timetable can shift for construction or low demand.

Moving Between Side Valleys: the Full Day Rule

The Kandertal is a single valley with four side branches that are dead ends. You cannot shortcut between them without returning to the valley floor. Oeschinensee, Gasterntal, Sunnbüel and Griesalp each consume a full day. A common mistake is assuming you can see Oeschinensee, Blausee, Gasterntal and the Gemmi in two days. You cannot. The valley is linear but the branches are separate pockets, not one continuous resort. Budget three full days minimum. The weather closes in fast, and you need a buffer to hit at least one high altitude objective like Oeschinensee or the Gemmi.

Oeschinensee: Arrive Before 09:00 or After 14:00

The Oeschinensee gondola queue in July and August can exceed 90 minutes starting at 10:00. The valley station is 800 metres east of Kandersteg, a 10 minute walk. Arrive before 09:00 or after 14:00. The gondola operates mid May to late October, plus late December to March. The lake itself is turquoise under sheer cliffs, UNESCO listed, and at 1,678 metres the Berghaus Oeschinensee serves Älplermagronen with apple sauce. No car access. Pedestrian and lift only.

Sunnbüel and the Gemmi Crossing

The Sunnbüel cable car valley station is 300 metres from Kandersteg. It operates late May to late October. From the top at 1,934 metres, the Gemmi Pass trail runs 3 to 4 hours to Leukerbad in the Valais. This is a one way crossing. Returning the same day requires a taxi or bus from Leukerbad via a 2.5 hour loop, not a quick shuttle. The Daubensee on the pass is bleak and wind scoured. The view faces the Doldenhorn massif. If you do not plan to cross, take the cable car up, walk the terrace, eat Rösti with melted Raclette du Valais at the mountain station, and ride back down.

Griesalp: Reserve Your Seat

The PostBus to Griesalp is not a hop on service. You must reserve for the Pochtenalp to Griesalp steep section. Call +41 58 448 06 22 the day before, before 16:00. Without a reservation, you will not be allowed on that section. Griesalp sits at the end of the road at high altitude, the start of serious trails into the Kanderfirn glacier viewpoint and the Ueschinen valley. The hotel serves wild berry tart with cream, berries foraged on the alp. Cash only.

Day Trips Beyond the Valley

From Kandersteg you can reach three destinations without a car. Thun is 40 minutes by train, with a lakefront old town and castle. Bern is 1 hour 10 minutes by direct train, UNESCO old town, no car needed. Spiez castle and vineyard is 25 minutes by train, on Lake Thun.

The Valais requires the car shuttle train. From Kandersteg, drive onto the BLS rail car at the terminal, remain in your vehicle, and drive off at Goppenstein a quarter of an hour later. The tunnel is 14.6 kilometres. Trains run every 30 minutes in each direction, first departure 05:05, last 23:05. Single fare for a car including passengers is CHF 27 to 33. No reservation is possible, first come first served. Peak summer weekends, Easter weekend and the Christmas New Year period can mean a 2 hour wait. From Goppenstein, bus into the Lötschental, a deep traditional Valais valley. Leukerbad thermal baths are reachable by walking the Gemmi (4 hours) then bus down, or driving 1 hour 15 minutes via the car shuttle.

What Most Often Goes Wrong

Visitors underestimate how long every walk takes. The side valleys are steep and the bus schedules are sparse. The trail that looks short on a map takes twice as long because the terrain is serious and the altitude is real. The Oeschinensee cable car queue. The Gasterntal no signal zone. The last bus at 16:30. The cash only huts. The mandatory reservation for Griesalp. The one way Gemmi crossing that requires a 2.5 hour return loop. Each one is friction you can plan around, but only if you know it exists. The single thing that most often goes wrong is arriving at a stop after 16:00 in a side valley and discovering there is no way back to Kandersteg until the next morning. Do not let that be you.
