Tested this today and it takes appr. 1h to bike from home (Interlaken) to Lauterbrunnen. The village and the valley is THE base jumping location, therefore also known as Death Valley. But base jumping aside, the valley and villages around and above offer amazing (and dramatic) background for many other activities too.
Play it tourist: see the 72 waterfalls and take the cablecar up to Schilthorn.
Play it biker: bike (or take the train / cablecar) up to Wengen. Winteregg, Mürren or my favorite (that little cute alpine hippie village) Gimmelwald. Choose your path and try to keep your eye on the road and not on the marvelous mountaintops, glaciers, gliffs, goats, chalets (mission impossible for me and therefore I take lots of breaks while up).
Play it hiker: hike (or take the train / cablecar) up to Wenger, Winteregg, Mürren, Gimmelwald… Hike a hour, two or whole day, find a hütte or hotel and take a beer.
Play it cool: bike the main road in Lauterbrunnen, past all the cafés and try to look as pro as possible.
Today I played the biker; took my bike up to Lauterbrunnen, then Winteregg and past carless Mürren and Gimmelwald back down to Lauterbrunnen and home. It was hot, it was tough, but it was all worth it.
Now I dream of 5-star hotel sheets and fondue dinner (yes, still no holiday in sight before September) but seems like I have to be happy with homemade pasta and H&M sheets. Which of course is more than fine too.
