Do you love the tanning goggles?
Lucerne also had a wonderful Medieval bridge, a Medieval wall (we couldn't walk along the top...again, we were there in the wrong season...this seems to be a recurring theme for us in Switzerland). Lucerne also has this giant lion carved into a rock wall. Strangely, I couldn't find a single mention of it in my Lonely Planet. Next to the little park where the lion is, is a glacial garden that was "discovered" in the late 19th century. We think something was missed in the translation, given that Lucerne was founded hundreds of years earlier. Needless to say, we skipped the glacial garden.
