2022 Warren County Parks & Trails Geocaching Amphibian Adventure

Grab your GPS, your binoculars and hiking boots, and get ready to explore! Find all 25 geocaches and collect the trading cards, April 1st- November 1st 2022. 

What is Geocaching? 

Geocaching is a real-world, outdoor treasure hunt using GPS-enabled devices. Participants navigate to a specific set of GPS coordinates and then attempt to find the geocache (container) hidden at that location. It is a world-wide hobby!

What is the Geocaching Amphibian Adventure?

There are 25 Geocaching Amphibian Adventure Caches hidden in county, state and city parks around Warren County. Your challenge is to explore parks and find them all using a GPS. Each cache includes an instruction card, a logbook, and a stack of constellation trading cards. Sign the logbook to show that you found the cache and take a constellation trading card for your collection. Discover the parks in the evening or your back yard and see if you can identify an amphibian.

After finding all 25 caches, take your 25 fish trading cards to the Annett Nature Center. We will give you the coordinates to find the last cache challenge. Take a picture of yourself with the very last card or all of your trading cards. Feel free to include family, friends, your dog or anyone else that helped you finish the challenge. All participants who successfully finish the challenge by November 1, 2022 will receive a finishers medal and your photo will be posted on our Facebook page as Geocaching Adventure Finisher. Then, take the winter months off and check back in the spring for the next geocaching theme.

Amphibians!

This is the 9th year of the Warren County Geocaching Adventure. We have done birds, insects, mammals, wildflowers, reptiles, trees, fish, constellations and now amphibians. This year features the amazing amphibians found in Iowa and few non natives. Learn fun facts as you explore your local parks and trails.

To Have a Habitat! 

Warren County is rich in natural diversity, providing essential habitat for a variety of plants and animals. During the adventure, you can explore Iowa’s four major habitats, woodlands, wetlands, prairies and river. Warren County Conservation and our state and city partners preserve and manage significant fragments of these essential natural landscapes, making them great sites for flowers, wildlife, and park visitors. Be extra observant while you look for the geocaches, you’ll be amazed at the natural wonders you can find in our parks!

Don’t know where to start? 

We welcome you to stop in at the Annett Nature Center to learn more about geocaching. Staff can provide helpful tips and info about geocaching during our business hours.  It’s best to give us a call at 515-961-6169 first before stopping out.

Rules of the Game 

Keep geocaching fun, safe and ethical by following the common-sense rules:
• Stay on marked trails wherever possible
• Tread lightly on the land and minimize impacts on the environment. Caches were placed above the ground in relatively well-traveled areas. There should be no need to disturb natural features to find a cache.
• Never remove or relocate a cache. Once you find it, open it to claim your prize, but then put it back exactly where you found it.
• You may find small trinkets left by other participants inside the cache. If you find one, it’s yours to keep. You can choose to leave a trinket for the next Adventure geocacher.
• Observe all laws and rules of the park.
• If you have trouble locating a cache, call us at 515-961-6169 for hints and tips.
