Simple
If planning a treasure hunt for younger children, consider some simple strategies. According to Creativekidsathome.com, the general rule is to limit the number of clues to the age of the child. Therefore, if your child were five years old, you would create five clues. For children not yet reading, use pictures as clues; for example, when the child found a picture of your dog's bed, he would venture to the dog bed to collect the new clue. An alternative to hiding and providing clues is to have a string treasure hunt. Simply wind colored string throughout the house and perhaps outdoors. People should follow their string whether it leads them up the stairs, around the bedpost, across the kitchen or out to the shrubs. After following their color of string, they should find their "treasure" tied to the end. Have a different color string for each participant. Unlike the last tip, this next one is meant only for young participants. Simply scatter change about in the yard or in gravel areas and let the children hunt.
Event
If you decide you host an all-day treasure hunt, consider adding some extras that will enhance the event and make it truly memorable. Send out themed invitations via messages in bottles or treasure maps. Both are easily available at party supply stores or you can create your own. Consider using some of the invitations as decorations. Toss some gold coin chocolates on the tables or perhaps some plastic and glass jewels. If you decide to have a grand prize from a drawing or raffle, decorate a box as a treasure chest and fill it with fun goodies; be sure to call the goodies "booty."
Mood
Set the mood by reading or creating a fun, spooky story of how the treasure came to be lost. To encourage participation or to make it more comical, have everyone get in a circle and add a line to the story. Also consider adding fun favors such as outlandish large or sparkling jewelry found at party supply shops, pirate hats or tattoos.
