‘Tü-ta-ta’ goes the PostBus horn. And, yes, there’s no denying that Europe’s steepest PostBus route from Reichenbach up to Griesalp sets the bar pretty high. In fact, the power with which the PostBus engines drive these buses up the meandering 28% gradient is simply astonishing.

It is only on the two-hour themed hike back down again that families, walkers and PostBus enthusiasts are able to immerse themselves fully into the wild and romantic world of the Kiental valley. The exciting trail not only features thundering waterfalls, stunning gorges and the wide expanse of Lake Tschingel, but also has 13 ‘stops’ along the way. If we follow the white signposts we are rewarded with lots of interesting information about the legendary yellow PostBuses as well as plenty of fun play areas between the Alp and our destination in the village of Kiental. Halfway along the trail is a BBQ area in the very heart of nature with phenomenal views, ideal for hungry adventurers to take a quick lunch break.

Public transport

Arrival Griesalp
First along the shores of Lake Tschingel, then through the hairpin bends of Europe's steepest postbus route: the journey from Kiental up to the Via Alpina hiking paradise and UNESCO World Heritage Site is spectacular.


Parkings Kiental
The destination has been decided, and so has the parking space - on this map, drivers can quickly and easily find the right parking option in the Oberland municipality. Well then: engine off, hiking boots on!

Safety instructions

Open hiking trails may also still be partially covered with snow. Hiking is at your own risk: Tourism Adelboden-Lenk-Kandersteg accepts no liability whatsoever when using local routes.


No need for heavy boots here this easy hike is well marked in either yellow or red white. Ofcourse, it can be steep at times, but there are also numerous mountain restaurants along theway
