During our mini holiday in Germany my brother and I went to Basel for a daytrip. When you stay in a hotel in Baden Wurttenberg you get a guest card, the Konuskarte. This card can be used in public transport and for discount on entree fees.
Our hotel was close to the Swiss-German border so we decided to go to Basel ( the card was valid for Basel as well). First we visited the Rathaus, a beautiful building!
After visiting the Rathaus we went to the botanical gardens of the university. We were surprised to hear the entrance was free. Nice, because everything else in Switzerland is very expensive compared to the prices in other countries. I especially loved all the different greenhouses.
