Descriptive digression
Factual travel writing benefits from a touch of colour, says Patrick Forsyth
Most travel writing must be factual. You are describing, perhaps recommending, a place, its history or how to get there.
Facts are important, but they can drain other, perhaps equally interesting, content away and leave a piece feeling rather pedestrian.
For example: Iceland is a wonderful place, but it is not the cheapest place to visit. When my son competed in a marathon there we went together and I tried hard to find a reasonable priced place to stay and restaurants that did not necessitate a mortgage being taken out. We always ate in one particular restaurant, and always seemed to be served by the same waitress. She told us she was a member of five minority groups: blonde, blue-eyed, Icelandic, female and a lawyer (well, a lawyer in training).
