Variant 1: Direct tour 30 km, 1200 vertical metres, 600 vertical metres
The direct tour variant starts in Grindelwald on the Schweizmobil cycle route 61 out of the valley along the black Lütschine to Zweilütschinen. Here we change to the Alpine Route 1 to Lauterbrunnen. In Lauterbrunnen, the second ascent begins on the signposted bike trail 450 in the direction of Mürren. From Mittelberg, we leave the signposted bike route and ride on an asphalt path along the railway line directly to Mürren. The car-free, unspoilt panoramic mountain village at the foot of the Schilthorn offers breathtaking views of the Eiger, Mönch and Jungfrau.

Variant 2: Difficult tour 35 km, 2100 vertical metres, 1500 vertical metres
The difficult tour variant starts with a longer ascent of a good 1100 vertical metres on a paved, car-free road to Kleine Scheidegg, the hub to the Jungfraujoch. Here you can take a break to top up your carbohydrate stores. And of course the impressive panorama of the Eiger, Mönch and Jungfrau is worth marvelling at. The signposted bike route no. 1 continues via Wengen into the Lauterbrunnen Valley, Switzerland's base jump mecca. The descent is steep, so solid riding technique and good brakes are essential. A short detour to the world-famous Staubbach Falls is well worthwhile. In Lauterbrunnen, we join up with the direct tour option described above.

60 km, 800 metres in altitude, 1800 metres downhill
From Mürren, the route takes you back on bike route 450 along small and sometimes steep asphalt and alpine paths via Gimmelwald to Stechelberg. Now you roll comfortably down the Lauterbrunnen Valley, past the Trümmelbach Falls. After Lauterbrunnen, you can choose to ride on the right side of the river on forest tracks and easy trails, Alpine Bikeroute 1 (GPS track) or on the left side of the river on the road. Depending on the time of day, you can expect quite a lot of traffic here. From Zweilütschinen, bike route 1 leads along the right bank of the Lütschine to Wilderswil and through Interlaken to the northern shore of Lake Brienz. From here, bike trail 451 leads to Brienz on partly paved and partly unpaved paths with constant ups and downs, always with a beautiful view of the deep blue Lake Brienz. In Brienz, we change to the Aare cycle path no. 8. The last kilometres of the day on the right bank of the Aare are a leisurely end to a long day of cycling.

30 km, 1500 vertical metres, 1050 vertical metres
On the last day of the circular tour, you will also be riding on Alpine Bike Route No. 1. The first attraction of the day is reached just after the first few metres in altitude: the legendary Reichenbach Falls, where Sherlock Holmes defeated his arch-enemy Professor Moriarty. Rosenlaui is reached after a further 400 metres in altitude. The spectacular glacier gorge can be visited on foot, the tour takes about 45 minutes. After a further 100 metres in altitude, the beautiful Chalet Schwarzwaldalp beckons with culinary delights. The tour now continues to the highest point of the day, the Grosse Scheidegg. From here, the rapid descent to Grindelwald begins with the imposing Wetterhorn behind you.
