Pojezierze Zachodnopomorkie?
zillions lakes and forests. It is nice to camp, swim, go mashroom picking, blueberry picking- the whole area is nice if one likes nature. Szwajcaria Polczynksa is close to Polczyn Zdroj and it is part of pojezierze Zachdniopomorskie.
Drawski Prk Krajobrazowy - Wildrover lives in the vicinity of it, so he can tell you more.
What in Krakow?
Old Town. Buildings, cafes, restaurants, pubs, bookstores. It is also nice to drive around Krakow and explore small towns and villlages with old cementaties, churches and synagogues and monasteries. Malopolska - (Krakow are is kind of magic due to history). I lived 50 km form Krakow and the rolling hills are amazing.
You didn't ask about Bieszczady;)
