Merryspring Nature Center in Camden will host its third annual Geocaching Festival on Sunday, Aug. 21 from 1 to 3 p.m. This is part of Merryspring’s free family summer programming co-sponsored by Camden National Bank.

Geocaching is the term used to describe the outdoor adventure game of hiding and searching for treasure boxes with the assistance of a GPS. The game is played all over the world by people of all ages, and is extremely easy to learn! What could be more fun than a treasure hunt with family and friends?

Merryspring’s Geocaching Festival features activities suitable for players of varying skill levels. Coordinates for the caches throughout the park will be made available at the event. In addition, fun trinkets will be offered for placement in discovered caches, but one can feel free to bring their own fun items to leave in the treasure boxes. If one already owns a GPS unit, please bring it to the event. If not several units will be available for the event.

The Geocaching Festival is part of Merryspring’s ongoing Outdoor Adventures series, led by environmental educator Sarah Lambson. Usually offered on the second Sunday of the month from June through September, Outdoor Adventures focuses on a different family-friendly, outdoor activity each month. A second series, Nature Explorers, is offered on the fourth Sunday of each month from June through September and introduces a different nature-based topic each month.

Family programs are offered at no charge. Activities are designed for ages 5 to 12, but are open to all ages. All children must be accompanied by an adult. In case of rain, please check for cancellation.

Merryspring is a member-supported, non-profit nature education center and park located at the end of Conway Road just off Route 1 by the Hannaford shopping plaza in Camden. For more information, call Merryspring at 236-2239 or visit the website at merryspring.org.
