This article is from the Hanggliding and Paragliding FAQ, by Joao Geada with numerous contributions by others.
A Paraglider folds down into a package the size of a largish
knapsack and can be carried easily. Conversely, a Hangglider needs a
vehicle with a roof-rack for transportation to and from the flying
site, as well as appreciable time to set-up and strip-down. It's also
somewhat easier to learn to fly a Paraglider.
