Nightline (Blindfold trail)

This challenge is great fun whether inside or outside.  The easiest thing to use is a rope, but you can use dog leads (extendible ones are great), dressing gown ropes, guide ropes from tents, or string.

Set a course around, under, and through different obstacles, then blindfold the player and set them off. It is even better if the course twists and turns to really put them through their paces. 

This makes a great team-building exercise when you have more than one person in a team. You can try timing it or working on your communications and teamwork skills by changing the course.
