Celebrating Geocaching’s Sweet 16!

Today, May 2nd, marks the 16th anniversary of the geocaching phenomenon. As we reminisce on all the wonderful geocaching moments we’ve experienced over the years, it’s fun to journey back to the year 2000 to see how it all began.

A Look Back in Time

The year was 2000. Y2K had come and gone. A dozen eggs cost 89 cents. “Survivor” was in its first season. The Summer Olympics were held in Sydney. Traditional outdoor activities at the time included hiking, bird watching, and camping. But then everything changed.

The Big Blue Switch

On May 2nd at approximately midnight, the “big blue switch” was pressed and selective availability on civilian GPS receivers was removed. Twenty-four satellites around the globe processed new orders, and the accuracy of GPS technology improved tenfold. Prior to this date, only the military had the ability to receive accurate GPS readings. Now, the world and all its wonderful people could pinpoint their precise location.

The First Geocache Hide

In celebration with this new-found freedom in global navigation, a computer consultant named Dave Ulmer started The Great American GPS Stash Hunt. The idea was simple: hide a container out in the woods and record the coordinates using  a GPS unit. On May 3rd, he placed a black bucket in the woods near Beavercreek, Oregon along with a logbook, pencil, and other various trade items – the first geocache. He shared the coordinates of his “stash” with an online community on sci.geo.satellite-nav and the “game” took off.

For the first few months, the stash game was played mostly by experienced GPS users who already used the technology for outdoor activities. Mike Teague, the first person to find Ulmer’s stash, began to gather other users’ posted coordinates and document them on his personal website.

Jeremy Irish, Founder of, stumbled upon Teague’s site while researching GPS technology and was intrigued by the idea. He purchased a GPS device and went out on his first geocaching adventure that weekend. After an enjoyable experience, Irish decided to start a website for the activity. Adopting the newly dubbed term “geocaching” and putting his web skills to good use, he launched with only 75 geocaches.

Geocaching in 2015: A Year in Review


2015 was an epic year in the world of geocaching. 

There were many laughs, plenty of new geocaches hidden, and a lot of “Found it” logs.  As we start to plan for the new year ahead,  it’s fun to reflect on many of the amazing things that happened in 2015. Here are 15 of them.


1) We celebrated 15 years of geocaching!

It’s hard to believe that the hobby we all love celebrated its 15th birthday this year. During this time of nostalgia, it’s fun to look back at some of the most historic moments in geocaching history.

2) A year of events. Great events.

  • 2 Giga-Events (5,000+ geocachers)
  • 45 Mega-Events (500+ geocachers)
  • Over 28,000 geocaching events total

It’s evident from all the fun gatherings that took place that geocachers enjoyed making new friends and spending time with the old at an average of over 76 geocaching events per day!  

  • A group of kiddos search for the code word at the last ever Geocaching Block Party Mega-Event in Seattle.

3) A group of courageous geocachers journeyed to the center of the earth to log an EarthCache. Well, sort of.

Need more laughs? Check out all the past geocaching April Fools videos:

4) The geocaching community grew.

In December, the 15 millionth geocaching account was created on Considering that many geocaching accounts represent families, couples, teams, and other groups, there are well more than 15 million geocachers worldwide.

  • Geocaching in Cambodia.

5) The game’s 453 community volunteers made the game better for everyone through their contributions as reviewers, moderators, and translators.

6) Geocachers joined in the global CITO (Cache In, Trash Out) movement and gave back to our lovely planet.

Over 19,000 geocachers collected garbage, restored natural areas, and worked on community improvement projects during CITO weekend in April. If each person picked up one 5 lb (2.26 kg) bag of trash, that’s over 40 metric tons of garbage collected. That’s (approximately) 7.4 elephants, or 7 elephants and two cows. This impressive number does not include the hundreds of additional CITO events that took place throughout the rest of year.

7) 4 incredible trackable branded promotions took place, including the super cute Mountain Warehouse promo.

With nearly 500 photos entered into the Mountain Warehouse photo contest, geocachers showed clever photography skills while shooting Meryl Sheep trackable tags all over the British countryside and beyond. One particular trackable, Wooliam the Sheep, has already traveled 32,000+ miles (51,499 km).


8) GeoTours expanded.

19 new GeoTours were launched this year, bringing the GeoTour grand total at 61 tours worldwide. The average number of geocaches per tour is 44, and their geocaches tend to have more favorite points than the average geocache.


9) Over 52,000 geocachers around the world went on a Geocaching Road Trip.

During the summer months, geocachers had the opportunity to complete five geocaching quests, each of which earned them a special souvenir for their geocaching profile. By completing all missions, they earned an extra special 6th souvenir. The theme was “Geocaching Road Trip”, and the adventures were epic.

10) Geocachers celebrated Pi. And puzzles. And ate pie.

While some folks celebrated Pi Day on March 14 (3.14) with a slice of pi pie, we celebrated this year’s Pi Day with two new souvenirs…and pie. The first souvenir was earned by 37,000 geocachers who attended an event on that day. The second souvenir celebrated the mystery of pi—to earn it, geocachers had to log a “Found It” on a Mystery Cache. Kudos to the 50,000 geocachers who took on that head scratching challenge.

  • Yummy geocaching events all day long!

11) Five new countries received their own geocaching souvenirs.

Time to update your bucket lists, geocachers. Cheers to Thailand, Turkey, Estonia, Lithuania, and Slovenia who were added to the growing list of country souvenirs this year!

  • Thailand Souvenir.

12) New features were added to make your geocaching world a bit better.


13) Geocachers watched 16 creative geocaching films at GIFF Weekend.

The GIFF (Geocaching International Film Festival) Weekend 2015 souvenir was awarded to over 14,000 geocachers who attended 449 GIFF events in 46 countries. That’s amazing. But what’s even more amazing is the sheer number of special and wonderful moments that happened at all the movie nights.

14) added new languages.

The website is now translated into 22 different languages including English. The iPhone and Android Free apps are also available in 19 different languages. More to come!


15) There were over 83,000,000 logged geocaches and over 588,000 new geocaches published this year.

Great job, geocachers. Great job.

  • Warm waters & lots of signatures.

From all of us at Geocaching HQ, thank you for making this year the best geocaching year to date.

A Guide to Geocaching in Thailand

Colorful is one word that perfectly sums up this unique and beautiful Southeast Asian country. Elephants and noodle soups, white-sand beaches and blue waters, Buddhist temples and ancient ruins, Thailand captivates the hearts of visitors from all corners of the world and leaves everyone with everlasting “Thai smiles” glued to their faces.


Like attending a Muay Thai boxing match, geocaching has joined the list of fun activities to participate in while in Thailand. There are currently over 1,300 active geocaches hidden throughout the country, all waiting to be discovered by visitors and locals alike. And to make things more exciting, *Thailand is the newest country to receive a Geocaching souvenir!

Although we all wish we could jump on a plane and head there now, this list of 5 amazing geocaches will have to do the trick. Enjoy!


1. GC2JDFG — Grand Palace
Cache Owner: JamieZel
Type: Traditional
D/T Rating: 1.5/1.5

PicMonkey Collage

There’s no place quite like the sprawling and bustling city of Bangkok. Golden Buddhist temples collide with large megamalls festooned with bright neon lights. And there’s no city quite as hot. Bangkok has an annual mean air temperature of 28°C. When geocaching, dress for the intense humidity and be on the lookout for muggles. This traditional cache was placed near the ornate Grand Palace which is a must-see attraction in the city. Afterwards, eat your heart out at any local food stand, as the street cuisine in Bangkok is phenomenal.

Be on the lookout for Siamese kitties as you wander the streets. They are native to Thailand.


2. GC24XKT — Ko Phi Phi Lee – (Mu Koh Phi Phi National Park)
Cache Owner: Calico-Jack
Type: EarthCache
D/T rating: 3.5/1.5


What’s a trip to Thailand without visiting the insanely famous island of Ko Phi Phi? This island served as the backdrop to the 2000 cult classic “The Beach” starring Leonardo DiCaprio. Although  the island is no longer uninhabited as it was in the film, it’s still just as breathtaking.


3. GC5G9N0 — Up and down! (Railay Lagoon)
Cache Owner: ChrisA33 & Damonstah
Type: Traditional
D/T Rating: 3/4.5


Rumor has it that the best cache in all of Thailand is located in the rock climbing paradise island of Railay. If they attempt it, geocachers are sent on an exciting and challenging adventure to a hidden blue lagoon. It’s no easy task, though. Bring good hiking boots and a friend you can lean on (literally).


4. GC932A — Thailand’s Highest Point
Cache Owner: Steve (Licorice)
Type: Virtual
D/T rating: 1/1


Thailand is home to some incredible mountainous regions. If you head up north towards Chiang Mai, also known as the “Rose of the North”, you’ll encounter these areas, all of which have been transformed into National Parks. This virtual cache is the location of Thailand’s highest point and the views are breathtaking. After exploring the area, spend some time wandering through the night markets and delicious restaurants in Chiang Mai.


5. GC48FEJ — Wat Mahathat
Cache Owner: thorshammers
Type: Traditional
D/T rating: 1.5/1.5


Located about five hours north of Bangkok, Sukhothai was the first ancient capital of Thailand (known as Kingdom of Siam at the time) from 1238 to 1438. The Sukhothai Historical Park is now a great place to explore. There are several geocaches hidden throughout the park including this well-placed micro. If time allows, explore some of the local rice fields. Thailand is the largest exporter of rice in the world!


*Thailand is the fifth and final Geocaching country souvenir to be released this year! Souvenirs are virtual pieces of art that are displayed on your Geocaching profile page when you find a geocache in certain locations. A list of of currently available Geocaching souvenirs and even the ones you’ve already earned can be found on And, if you’ve already found a geocache in Thailand, we will retroactively add this souvenir to your profile in December 2015.
