Big Springs is an amazing natural spring located in Island Park, Idaho. It's in Fremont County, a beautiful part of the state. This spring is super special because it's a "first-magnitude spring." This means it's one of the biggest and most powerful springs in the world!

Every single day, Big Springs pumps out over 120 million gallons of fresh water. That's enough water to fill many swimming pools! This huge amount of water becomes a main source for the Henrys Fork of the Snake River. This river is very important for the local area.

Discover Big Springs

Big Springs is famous for its huge rainbow trout. These fish gather near the bridge, waiting for visitors to feed them. You can use coin-operated dispensers to get fish food. It's a fun experience to watch the fish jump and splash!

Fishing is not allowed right at the springs. You have to go several miles downstream, past the outlet to Henry's Lake, before you can fish. This helps protect the fish population at the springs.

What Makes Big Springs Special?

Big Springs is truly unique. It's the only first-magnitude spring that flows out of rhyolite lava rocks. Rhyolite is a type of rock formed from ancient volcanic eruptions. This special geology makes the spring's water incredibly clear and pure.

Because of its unique features, Big Springs was named a National Natural Landmark in August 1980. This means it's a nationally important natural area that deserves protection.

The spring is located within the Caribou-Targhee National Forest. The United States Forest Service helps manage and protect this beautiful site. They make sure visitors can enjoy it while keeping the environment safe.

Wildlife and Nature

Big Springs is a great place to see wildlife. There's a half-mile long trail that's easy to walk, even for people using wheelchairs. As you walk, keep an eye out for different animals.

You might spot Osprey and Bald eagles flying overhead. Many types of Waterfowl (like ducks and geese) live in the water. If you're lucky, you might even see a Moose, White-tailed deer, or a Muskrat near the water's edge. It's a perfect spot for nature lovers!

The Johnny Sack Cabin

Right next to Big Springs, you'll find a historic log cabin. This cabin was built by a man named Johnny Sack in 1929. It's a charming old building that shows how people lived long ago.

Today, the Johnny Sack Cabin is open for visitors to explore. It's a neat place to step back in time and imagine life in the past.
