We are planning to be in Austria in September. We would fly into Salzburg, stay a couple of days and then head to the Mountain/Lake region. We are leaning towards St. Gilgen and the Gastof Furberg Hotel. We like the seclusion it brings. Getting to Hallstatt and other mountain/lake towns in other areas can be achieved via public transportation? What is the climate in these areas in Sept? If you travel to towns within Lake Wolfgang by boat, how much is the charge. Thanks in advance for all your help.
