Man those are gorgeous!

Thanks -- it was even better to be riding there that day.
My thanks go to a couple of people on this newsgroup who recommended Grosse
Scheidegg. It's in some of Jobst Brandt's trip reports. Otherwise I would
never have have thought of trying it.
And thanks to the Swiss folks who marked Bike Route 61.

I want to learn more about the bike trip, and how
many miles you could get in there.

It was around 52 miles / 85 km as a loop from Interlaken to Grindelwald,
over the Grosse Scheidegg pass and down to near Meiringen, finally around
the northwest side of the Brienzersee (thanks to Jobst for pointing out that
would work) back to Interlaken. But the miles are not the main issue, it's
about the climbing -- roughly 5000 vertical feet / 1500 meters. And the
there's some sustained steep sections between Grindelwald and the pass,
something like 10% (which is steeper than most of Alpe d'Huez or Stelvio). I
have photos of a guy walking his bike up. Since I had my camera, I used that
as my excuse to stop and rest lots of times.

A different strategy would be to pedal up Bike Route 61 from Wilderswil
(near Interlaken) to Grindelwald (only a few short steep sections), then
take the post-bus up to the pass (I think I saw bike racks on the back of
the bus). Yet another strategy would be to take the train from Interlaken to
Grindelwald, then the post-bus up to the Grosse Scheidegg pass -- and ride
back down the west side back to Grindelwald and then mostly downhill back to
Interlaken. The main disadvantage of that last is that you miss out on the
views riding _toward_ the Wetterhorn mountain while riding uphill to
Grindelwald.
