You can live your whole life in the great state of Montana and never see it all, though the outdoor-loving types who reside here certainly enjoy trying. So it comes as no surprise that The Treasure State is full of hidden gems that not many people know about. On your next trek through familiar terrain, venture off the beaten path and explore some of these lesser-known hidden gems in Montana:

1. Yaak Valley

Did you know Montana has a rainforest? Tucked up in the most northwestern corner of Montana (bordering Canada and Idaho) is the Yaak Valley, with an incredible wildlife population and beautiful spots to camp.

2. The Garden of One Thousand Buddhas, Arlee

Montana might seem like an unlikely site for a Buddhist garden, but this spiritual site has been in the works since the year 2000. It is the founder’s goal to have the garden inspire Buddhist ideals of joy, wisdom and compassion in a place where Eastern philosophy is not widely known or practiced.

3. The World's Shortest River

Located just outside of Great Falls, the Roe River spans just over 200 feet. It holds the world record as the shortest river, and you can walk the length of it in a minute.

4. The City Underneath Havre

Havre, Montana was nearly wiped out by a fire in 1904. Many of its business owners decided to move underground, creating a series of tunnels within a six block radius. You can see it all by taking the Havre Beneath the Streets tour.

5. Outlook Inn Bed and Breakfast, Somers

Want to take in the beauty of Flathead Lake and Glacier National Park without having to camp? This little bed and breakfast will offer you all the comforts of home, and it sits right on the north end of the lake.

6. Polebridge

This tiny town of under 200 residents is only 35 miles south of the Canadian border. It’s also an amazing little spot to visit to get away from it all; between the affordable cabin rentals, the close proximity to Glacier National Park and the Polebridge Mercantile, you’ll have everything you need to relax and enjoy life.

7. Judith Gap

Drive through this small gap between the Big Snowy Mountains and the Little Belt Mountains to check out the state’s first wind farm, Invenergy. It's a delight of a town!

8. The Boiling River

Most people visit Yellowstone without ever knowing this place is a mere two miles away from the park’s North gate. The Boiling River is a combination of the hot water from Mammoth Hot Springs and cold water from the Gardner River, allowing the water temperature to cool enough for people to soak in.

9. Makoshika State Park

Makoshika State Park doesn’t get as much hype as Glacier or Yellowstone, but it’s every bit as breathtaking.

10. Moss Mansion Museum

At a time when the average home cost $3,000, Mr. and Mrs. Moss spent $105,000 building their abode. With three stories, 28 rooms and an attached solarium, it’s now a preserved historic site.

11. The Ptarmigan Tunnel

Glacier National Park’s only tunnel is 250 feet long and was originally built for horses. The Ptarmigan Trail is recommended for experienced hikers only.

12. The Cathedral of St. Helena

If this neo-Gothic church seems out of place for Helena, it’s because it was modeled after a famous church in Vienna Austria. Guided tours are available on Tuesdays and Thursdays.

13. The Prairie County Museum, Terry

Visitors to this hidden gem museum will find a gallery dedicated to Evelyn J. Cameron, who gave up a life of wealth and privilege in England to start a new adventurous life in Montana with her husband. Her story and her photos are inspiring.

14. The Ringing Rocks, East of Butte

The Ringing Rocks (sometimes called "Singing Rocks"), are one of the most unique rock formations in the country, and they chime when you tap them lightly with a hammer.

15. Daniels County Museum and Pioneer Town

Located about 20 acres west of Scobey, 35 historic buildings have been restored to depict a town from the early 1900s and preserve the history of the area.
