Below some suggestions where to go in Kraków for picturesque sights. Something to explore city, and escape from noise and traffic.
Aleja Waszyngtona (Las Wolski)
Alley that leads to the Kościuszko Mound, and Wolski Forest(when there are more nice sights). It is about 1 km of climbing, nice views, some monuments of nature on the side.

Probably the best view in Kraków(apart from some towers) is from the top of Krakus Mound. Mound itself has quite intriguing history, and is surrounded with rather green, calm area.
About half hour walk away from Qubus Hotel, hour from Main Railway Station.

Stadion Korony, Park Bednarskiego, Krzemionki
Above 100 years old stadium, old-fashioned and haven't renovated for a long time - it's more like a monument then actual stadium. Surrounded by park, and trees. Name "crown" is quite fitting - Stadium is located at something like a plateau above the city.

Mysterius and quite disturbing valley below Krakus Mound, and next to former Nazi German concentration camp where there used to be stone-pit and labor camp during II World War. Filled with trees, partially covered by water and rather wild place. Remnants of Schindler's List set are to be found there.

Zakrzówek, Skałki Twardowskiego
Picturesque lake, cliffs, rocks and trees. This is still quite wild place although part of it is separated by fences and entry is paid. Very nice view from some of highest spots.
Probably the best access through Twardowskiego street(near Kapelanka tram stop) or Norymberska street.

Very fitting to visit one of those at sunny day during polish golden fall.
