There is nothing special about Szczawnica, but somehow I liked it. It did not feel touristy at all to me and I saw a lot of potential for having fun there, especially during summer months. It is located directly at the Dunajec river and there were many companies advertising rafting trips on the river. There were also several bike rental companies and it looked to me like it would be fun to bike there. One idea that I had was to bike to all building belonging to the "Trail of Wooden Architecture", which spans whole Malopolska.
