naturtrip.org is the first public transport information where you do not have to know the destination. After all, when it comes to excursions, one usually does not know exactly where one wants to go, but only what one plans to do. Namely eat delicious, relax in the spa, dozing or paddling in the sun. Therefore one searches with naturtrip.org from A for "Strandbad" or "Kanuverleih". And how long you want to be on the road. 30 minutes, 60 minutes or more. Then you get on the map exactly the destinations shown, which can be reached from your own location in 30 min or 60 min currently by train, bus or bike.
