Compatibility in a travel companion is key for trips such as backpacking. Since certain trips do not come with a set itinerary and leave room for improvisation it is important to pick your travel companion(s) wisely. You will be spending a lot of time with this person in a lot of unfamiliar places and situations so you will want to know what you are getting into in advance.
1. Good Sense of Direction
Someone who can read a map and has a good general sense of direction can be really helpful when travelling. If you plan on using public transit abroad keeping your orientation can be very difficult, so this is an invaluable trait for a companion if you are directionally challenged.
