Modern-day treasure hunting happens right here in our parks! Geocaches are hidden containers filled with interesting stuff that you track down using GPS units. Learn how to use a GPS unit, and spend the day on a geocaching adventure in search of local caches. Bring a snack, water, and be prepared to hike (long pants and sturdy shoes strongly recommended). If you don’t have a GPS unit, we'll lend you one. Please register and pay for all participants at ParkPASS.org.
Meet at the Lake Needwood Boat House (15700 Needwood Lake Circle, Rockville, 20855).
