Merryspring Nature Center in Camden will host the second annual free family Geocaching Festival on Sunday, Aug. 8 from 1 to 3 p.m.

Geocaching is the term used to describe the outdoor adventure game of hiding and searching for treasure boxes with the assistance of a Global Positioning System receiver. The game is played all over the world by people of all ages, and is extremely easy to learn.

Merryspring’s Geocaching Festival features activities suitable for novices as well as experienced players, and participants will be able to learn how to best use their GPS units. 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 attendees can bring their own fun items to leave in the treasure boxes. Participants that own a GPS unit should bring it to the event. Several units will be available for loan.

The Geocaching Festival is part of Merryspring’s ongoing Outdoor Adventures series. The series is led by environmental educator Leo Maheu and offered on the second Sunday of the month from June through September. It 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 nonprofit 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 visitmerryspring.org.
