The Linn Parks Challenge offers adventure without requiring a lot of travel time. This geocaching adventure serves as a reminder that Linn County parks and preserves are never too far away.   It gets folks outside and introduces families to the wide array of beautiful public spaces that are available.

What is a geocache?

Geocaches are small containers with a log book, crayon, and rubbing plate inside. You must use the crayon to create a rubbing in the passport of the secret word for the corresponding cache.  

Discover wildlife areas, trek through the woods, and stretch your legs on a trail. The great part about this challenge is that by the end you’ll know where tons of cool places are to hike, bike, camp and explore.
