Sometimes a city break just doesn't cut it, sometimes you need a big holiday. A massive one even. An adventure of such scope that, realistically, you'll only get to do it once in your lifetime — which is exactly what we have right here.

The folks at online travel agency FlightNetwork recently collaborated with more than 500 travel journalists, agencies, bloggers and editors from around the world to compile a list of the 50 most transformative journeys you can take on the planet Earth... which should make booking your next holiday a wee bit easier.
