A well-planned treasure hunt should be challenging without being too frustrating. Consider the ages of the players. If the party is for a group of four-year olds who can't read yet, consider visual clues. Before the party, take snapshots of different items and tape them to colorful placards or you may make drawing of the clue itself. Hand these out to the teams and let them look around the room or area for the items pictured or drawn until they find the other clues that lead to the treasure. Older kids might enjoy a treasure hunt in with riddle like clues or things that are found in popular books like Harry Potter, Narnia and the like. Make it really interesting and provide a special prize for the first team to turn in ten treasures. A treasure hunt is a great exercise in team work, and well-thought out clues can also make it a great learning activity. Consider the occasion and the interests of your guests, then create your clues around them.
