The original Riverboxes™ Challenges and its associated geocoins have been retired. Many thanks to all who participated in the original challenges! 

Take the Riverboxes™ Challenge II: SWACO Challenge!

Explore and discover all 16 Riverboxes (artist-created vessels inspired by letterboxing and geocaching) placed throughout Dublin, Ohio parks, and keep Dublin’s parks clean and beautiful along the way.

To take the SWACO Photo Challenge, visit to retrieve clues for each Riverbox. Upon finding each Riverbox, snap a picture of yourself with the Cache In Trash Out (CITO) kit (trash dispenser with trashbags, CITO information) at each Riverbox. Once you’ve taken all pictures, visit Dublin Arts Center at 7125 Riverside Dr., Dublin, Ohio to conclude the Riverboxes Challenge II and receive your custom CITO kit.

Cache InTrash Out is an ongoing environmental initiative supported by the worldwide geocaching community to preserve our environment. Please use the trash bags provided at each Riverbox to collect and dispose of any trash found during your adventures. Additionally, you can bring a photo or your full bag of trash to Dublin Arts Center to receive your own dispenser to continue your CITO efforts wherever you go!

If you post your challenge photos online, remember to tag @DublinArts on Instagram and Twitter and use #Riverboxes to share your adventures!
