Try one of these challenging outdoor sports for an unusual -- and thrilling -- family adventure.

Geocaching

This sport requires a handheld GPS or a cell-phone app and a membership to geocaching.com (free for general use; premium membership, with custom searches and alerts, costs $10 for three months). A treasure hunt that's played globally, geocaching involves finding a "cache," usually a waterproof box, that another enthusiast has hidden. There are more than a million caches stashed all over the world. Enter the coordinates to a local cache, lace on your hiking boots, and take the family on a treasure hunt. When you find it, take a prize from inside -- usually small trinkets like toys, buttons, or coins -- and leave something for the next family to discover on their hunt.

Orienteering

Using only a map, a compass, and your general sense of direction, you run, hike or bike -- even canoe -- a several-mile-long outdoor course from point to point and race to complete the challenge in the fastest time without making any mistakes. Go to us.orienteering.org for events near you.

Caving

It's not for the faint of heart (or anyone who's afraid of bats), but exploring underground caves can be an exciting experience. You'll use maps, gloves, and your own strength to navigate into the world below the earth's surface. Of course, don't head into the dark without proper training and the right equipment. Visit caves.org for information on spelunking clubs and safety tips.
