Geocaching in Maryland
Enjoy a treasure hunt in nature!
Geocaching is a fast-growing hobby that provides an exciting way to explore the outdoors. Players try to locate hidden containers, called geocaches, using a smartphone or GPS, and can then share their experiences online.
It's a great way for kids to connect with nature and learn navigation skills, with the fun reward of finding real hidden treasure.
Geocaches can be found at select TNC public access preserves in Maryland. We invite you to explore these natural areas in this fun and free way. It's a great hobby, and you may learn a little about our work as you play!
Once you set up a free geocache account you can start the hunt for geocaches placed by MarylandTNC at these preserves:
- Frank M. Ewing / Robinson Neck Preserve
- Nassawango Creek
- Hellen Creek Hemlock Preserve
- Battle Creek Cypress Swamp
- Nanjemoy Creek
- Sideling Hill Creek
- Selinger Marsh
- Finzel Swamp

Please review our preserve guidelines before your visit, and keep these tips in mind during your outing:
- Please leave pets at home. Dogs are not allowed at any Conservancy preserve.
- Caches are only accessible during normal hours of operation.
- Stay on marked trails at all times.
- Do not litter; used marked receptacles to dispose of any trash.
- Please respect the land; do not remove plants, animals, artifacts, or rocks.
- For your safety and comfort, bring drinking water, hats, sun protection, bug repellent and use appropriate footwear.
New geocaches are not permitted on TNC preserves. These sites were carefully selected for their accessibility and low impact to the environment. For questions about geocaching at The Nature Conservancy’s preserves in Maryland, please contact Deborah Barber at firstname.lastname@example.org.
