Beautiful Place to Visit in Idaho – Minnetonka Cave

The History & Formation of Minnetonka Cave

Minnetonka Cave is a karst limestone cave, created over millions of years by groundwater flowing through the rock. This process carved out intricate sinkholes, underground waterways, and the remarkable formations that make the cave so unique today. The cave is estimated to be around 350 million years old, a testament to the slow and steady power of nature.

The cave was discovered in the early 20th century, though its exact history prior to its discovery remains shrouded in mystery. Since then, it has become one of Idaho’s premier show caves, welcoming over 40,000 visitors each year. Managed by the Montpelier Ranger District, Minnetonka Cave remains a protected natural treasure, providing a glimpse into the Earth’s ancient past.

The Guided Tour Experience

A visit to Minnetonka Cave is an adventure that combines education, exploration, and a bit of a workout. The guided tour covers approximately three-quarters of a mile and takes about 60 to 90 minutes. Along the way, guests descend and ascend 888 steps (444 down and 444 back up), providing an up-close view of the cave’s stunning formations.

Tours are led by knowledgeable guides who stop at key points throughout the cave to explain its geology, history, and unique features. Visitors have the chance to learn about the cave’s “living” formations, such as stalactites and stalagmites, which grow at a rate of about one-thousandth of an inch per year. The no-touch rule ensures these delicate formations continue to thrive for future generations.

Highlights of the tour include:

• Cave Bacon: Wavy, layered flowstone formations that resemble strips of bacon.

• The Wedding Chapel: Featuring a stalactite and stalagmite growing toward each other, often likened to a bride and groom.

• The Treasure Room: Known for its formations that resemble stacks of gold coins.

• Dwarf Kingdom: Home to formations resembling figures such as the Seven Dwarfs, a dove, and a black bear.

One of the most awe-inspiring features is a cavern with a ceiling that soars 90 feet above the cave floor, showcasing the cave’s vastness and grandeur.

Visiting Minnetonka Cave requires some preparation to ensure a safe and enjoyable experience. Here’s what you need to know:

• Wear Appropriate Clothing: The cave maintains a cool temperature of 40°F year-round. Bring a jacket or layers to stay warm during the tour.

Minnetonka Cave features nine rooms filled with incredible geological formations. Guided tours highlight the most striking features, including stalactites (formations that hang from the ceiling), stalagmites (formations that rise from the floor), and the colorful “cave bacon.” Some formations, such as columns, form when stalactites and stalagmites meet, creating tall, pillar-like structures.

Visitors are often mesmerized by the intricate patterns and textures of the formations, many of which resemble familiar objects or figures. Each guide adds a personal touch to the tour, sharing stories, pointing out hidden details, and answering questions.

The ambient lighting in the cave enhances the viewing experience, casting shadows and highlights that reveal the formations’ true complexity. Some areas are darker than others, adding a sense of mystery and adventure to the journey.

Protecting the Cave & Its Residents

Minnetonka Cave serves as a sanctuary for five species of bats, which use the cave as a hibernation site during the winter months. To protect these important pollinators and pest controllers, strict measures are in place to prevent the spread of White-Nose Syndrome. Visitors are asked to clean their shoes and avoid bringing items that have been in other caves or mines.

In addition to bat conservation, the cave is protected as a natural resource, with regulations in place to preserve its fragile formations. Touching the formations is prohibited, as the oils from human skin can halt their growth.
