TDF is not a beautiful place, but I think that Kau Tappen is worth every penny.Other guests who are more fortunate than me rattled off a list of equals(Ponoi, Silver Hilton etc.)that leads me to believe that it is among the best.
It was the fishing in the north that I was a little disapointed with. We fished the Majeo,Traful, and a few others. As far as cost, I can't think of a place in the States that costs as much(eg.Elk Trout) but I can think of a bunch of free spots that are equevelant. You wouldn't drive five hours to get to any of them. Like I said, I would stick to the public waters.
I will say that no one else seemed to mind. To each his own. The wine and BBQ. is world class down there. Maybe I just don't like fishing for trout with guides.
Any way, I had the time of my life, and loved every second.
