For those that were not Boy Scouts or Girl Guides, be prepared.
The average daily temperature is about 8°, with evenings at 4°. The weather will probably include a few rainy days, so be prepared with layers of clothing, with gloves and a hat being good ideas.
The tour will not include a lot of hiking, however waterproof hiking boots are a good idea.
All dining and evening events will be informal and relaxed.
