Gosh, Carolyn, coming from one of the most beautiful sections of our country with the best summer weather for hiking / walking (they really are the same thing) from a family known for hiking (your mom's) how did you grow up not loving to walk in the beauty of nature?  It's a Northwest thing, a German heritage thing, a family thing.  What happened?
Maybe it is an area for new adventures -- and they are there.  Nature and wilderness hold amazing discoveries which apparently are still unfamiliar to you.  Bulgaria surely has these types of adventures as well.  You don't have to give up the city adventures to add in a new flavor to your life.  Just make sure you wear good shoes!
