It is, according to the folks at Twin Lakes State Park, the perfect time of year to use GPS units to find caches, or containers, in the woods. Geocaching is a “great way” to get out and explore the park’s beauty while finding hidden treasure.

GPS units will be provided, but participants are asked to bring some SWAG — “Stuff We All Get” — of their own. This would include trade items, normally small trinkets like stickers or key chains, left in caches by geocachers.

The one-hour adventure starts at 11 a.m. Saturday at the park, 788 Twin Lakes Road, Green Bay. Call (434) 392-3435 or email TwinLakes@dcr.virginia.gov for more information.
