Behind the Notre Dame is Pont de l'Archevêché bridge. Adorned with hundreds of padlocks, it is quite the site. This trend is becoming ever so popular. Write your loved one's and your name on a padlock and attach it to the bride. Then, throw the key into the Sein river as a symbol of your undying love. Quite the romantic gesture.
The Bernese Oberland was our four day stop in our three week journey through Europe2013. We stayed three nights in Grindelwald at hotel Tschuggen, which gave us two full days for hiking. There are a couple of nice towns in the Jungfrau region so if you are finding it hard to find a hotel in Grindelwald, you may want to try Lauterbrunnen, Wilderswil or Interlaken.
