From Wikitravel

The geographical hierarchy is one way to think about and organize travel articles -- breaking down big areas on Earth's spherical surface into smaller and smaller areas until you get to areas too small to be worth writing an article about. But it's just one of many ways of thinking about travel articles, and to form meta-articles that group other articles together. Some other ways are listed below; there are probably more.

Itineraries

An itinerary views a group of destinations according to a temporal (time) division rather than a spatial one. For example, Summer in Europe, One month in Vietnam, or First trip to Asia could list some cities and countries to visit during that amount of time, with recommended durations of stay. Weekend from New York might list multiple itineraries in Long Island (New York), Connecticut (United States of America), or other destinations.

Other itineraries may cross geographical regions, but have a well-defined path. The Appalachian Trail or Route 66 are good examples here.

Fields of pursuit

Not all travellers are looking for general adventure and art museums. Some specific guidelines or itineraries for people who follow a particular field of pursuit -- like Surfing or Birdwatching -- might be reasonable articles. They could point, in turn, to great places or regions for this pursuit, or to more specific itineraries. Two months surfing the South Pacific or Trekking in Nepal for example, could give an itinerary for hitting all the best waves from Tasmania to Okinawa.

Issues in travel

It also makes sense to think about travel issues -- Gay and lesbian travel, Honeymoons, First aid, Disabled travellers, Travelling with children. Some information on these issues may go into geographical descriptions, but other more general info might be valuable in its own article.
