A family outing to the Civil Defense Caves near Rexburg, Idaho, offers a fascinating blend of adventure and history, ideal for curious minds and outdoor enthusiasts alike. These unique caves, formed by ancient lava flows, provide a captivating glimpse into both geological formations and Cold War-era preparedness.

Getting There

The Civil Defense Caves are located about 15 miles west of Rexburg, Idaho. From the town, take Highway 20 eastbound, then turn north onto County Road 8. Follow the signs leading to the cave entrance, which is easily accessible by car. Parking is available at the trailhead, though it’s advisable to arrive early to secure a spot during peak times.

A Historical Perspective

During the 1950s and 60s, the U.S. government constructed these caves as part of a civil defense strategy. Designed to serve as shelters in the event of nuclear attacks, the caves represent a tangible piece of Cold War history. Though they were never used for their intended purpose, they stand as a testament to the era’s anxieties and preparedness efforts.

The Cave Experience

Exploring the Civil Defense Caves is a fun experience for families. The caves are relatively easy to navigate, but there are some tricky spots where you have to climb over rocks, and remember, it’s dark! Inside, you’ll find a giant cave that goes back so far that if you turn your flash light off, you can’t see your hand in front of you, providing an exciting sense of discovery. The temperature inside remains cool year-round, making it a refreshing escape from the summer heat.

Tips for a Safe and Enjoyable Visit

1. Dress Warmly: The cave environment is cooler than the outside air, so bring layers to stay comfortable. (Even in the summer when it’s hot outside!)
2. Bring a Flashlight: It’s completely dark once you get a ways in so you will want a flashlight. We love the little headlights for kids from Walmart!
3. Wear Sturdy Shoes: The cave floor is rocky and uneven and you do some climbing, so durable footwear is essential.
4. Respect the Environment: Unfortunately it has become a place where there is a lot of graffiti. Don’t add to that so you can help preserve the natural beauty for future visitors.
5. Check Conditions: Weather or seasonal conditions might affect cave accessibility, so check local advisories before heading out.

A visit to the Civil Defense Caves near Rexburg is not just a journey through intriguing underground landscapes, but also a dive into a unique piece of American history. With its blend of adventure and educational value, it’s a perfect destination for a family outing.
