Based on Rick's comments about Hallstatt and how he loves it there,we took a trip to Hallstatt from Vienna. We splurged and used a private taxi service to take us door to door.
We were there earlier this month (October).We've travelled many times to Europe at this time since the crowds are less. I don't know when the last time Rick was actually in Hallstatt but we were shocked beyond words to find busloads of tourists being dropped off at the entrance to the town. So much so that you couldn't even move on the street that goes along the lake.Apparently, the crowds of buses are like that all year around now.
Good thing we chose a place to stay that wasn't built on the side of the hills. There didn't seem to be any way to get up there other than to climb. Our guesthouse was a lovely 20 minute walk into town.
From there we used CK Shuttle (based on reviews here) to get to Chesky Krumlov and then again used them to get to Prague.
