Join us on Saturday, November 6th at 1 p.m. for a fun filled geocaching adventure, where we will learn what geocaching is all about, how it works, and then go on a modern-day treasure hunt to find some ‘caches!

What is geocaching?

Geocaching is a game that involves hunting for treasure. There are over 3 million hidden containers called geocaches hidden worldwide just waiting to be found. You can follow the clues to find them using a GPS device (Global Positioning System).

What will I find?

The containers, called caches, can be of all shapes and sizes. Inside, you’ll usually find a log book to sign or initial that you’ve found it. You might also find little toys or baubles called “loot” to keep as a mini trophy. However, it is considered good etiquette to leave something behind if you take something, so there will always be something for future geocachers. But leave the container where you found it! You can also log your finds online through various geocaching sites and apps. 

What should I bring?

The best gear a geocacher should have is:

  • A GPS device or cell phone with a GPS or Geocaching app installed (make sure your phone is in a protective case in case it is dropped).
  • A pen to sign the log book when you find it.
  • A couple of small trinkets to replace what you take from the cache.
  • Water! Always have water if you’re going on a longer than usual hike.
  • A portable phone charger will come in handy as well.
  • Sunscreen.
  • Bug repellent.
  • A first aid kit (especially if you are doing a day hike).
  • A backpack to keep it all together.

Geocaching Safety Tips

  1. Always let somebody know where you’ll be geocaching. If possible, share your location with someone you trust through your phone. Ultimately, you should never geocache alone. There is safety in numbers!
  2. Have your phone fully charged. Sometimes you will be out of range if you are going to some locations, so be prepared!
  3. Dress appropriately. Long pants are best, in case you need to climb over rocks or through thorny bushes. Good sturdy shoes like hiking boots are a plus, too!
  4. Geocache during the day, preferably during dry weather, as some surfaces can be slippery, such as rocks and logs.

How to Geocache

  • First you need to find a geocache location. There are multiple places online in which you can search for them:
  • Once you find a spot you’d like to search, you’ll have the coordinates.


A geocaching location is revealed mainly by its coordinates, specifically, latitude and longitude.

Latitude: The horizontal lines that go around the Earth from east to west.

Longitude: The vertical lines that cover the Earth from north to south.

When a latitude coordinate crosses over a longitude coordinate, then X marks the spot!

Like a circular clock, which is divided into hours, minutes, and seconds, the measurement around the spherical earth is also divided into degrees, minutes, and seconds. Each line that you see representing latitude or longitude is 10 degrees and is then broken into smaller segments, minutes and seconds, for more accurate measurements. 

One degree of latitude equals approximately 364,000 feet (69 miles or 111 km), one minute equals 6,068 feet (1.15 miles or 1.9 km), and one-second equals 101 feet (30.8 meters).

Measuring starts from two places. The measurement of latitude starts at the equator. Heading north from the equator, each line is increasingly ten degrees farther north, and heading south, each line is increasingly ten degrees farther south. 

Take this example: 

N 47° 38.938′ W 122° 20.887′

Because the coordinates start with N, we know that this location is north of the equator. Because the first number—which indicates the degrees—is 47, we know that it is 47 degrees, so four and 7/10ths lines of latitude above the equator. The next numbers are 38.938. This is a further precision of the measurement into minutes and seconds, meaning this location is 38 minutes and .938 x 60 seconds (almost 1 minute) farther north. (source)

The Search Begins! 

If you are using a GPS device or a phone with a GPS app (mapquest, Google Maps, WAZE, etc.), enter the coordinates into the device.

Let’s try an example: 

38°37’08.9″N 76°55’59.8″W

  1. Open the Google Maps app.
  2. In the search box at the top, type your coordinates. Here are examples of formats that work:
    • Degrees, minutes, and seconds (DMS): 38°37’08.9″N 76°55’59.8″W
    • Degrees and decimal minutes (DMM): 38 37.089, 76 55.598
    • Decimal degrees (DD): 38.37089, 76.55598
  3. You’ll see a pin at your coordinates.
  1. Enter numerical coordinates for latitude and longitude in the Search bar  
  2. Longitude: East is positive, West is negative
  3. Latitude: North is positive, South is negative
  4. Tap Search.
  5. So this example would look like this: 38 37.089, -76 55.598
  6. (Note: WAZE does not let you zoom in as closely as Google Maps)

If you are using a geocaching app, you can simply look up the location of the cache, and follow the display map directly to the location, or you can enter the coordinates into the device. I suggest using the app called Geocaching with the geocaching logo.
(Note: There is a premium subscription available for unlocking special locations, but that will not be necessary for this program).
