Growing up in Montana meant that I spent most of my summers enjoying time on one of the many incredible lakes that are available there. These lakes in Montana were part of my childhood and still remain a huge reason why I journey back there every summer--my family has a lake home on Flathead and we have to make the most of it!

The absolute most beautiful lakes in Montana to visit

You won't want to miss these lakes in Montana on your Montana road trip!

Flathead Lake

Potentially the most visited, and most famous, Montana lake, Flathead Lake is the largest natural freshwater lake in the western US (by surface area) outside of Alaska and the largest lake in Montana. 

With plenty of public access sites that provide boat ramps, camping sites, electricity, and utilities, there is no wonder why Flathead is one of the best lakes in Montana. I also recommend checking out Flathead Lake State Park if you need a free launch!

Surrounded by the Mission Mountains with over 187.6 total miles of water, there are no limits to activities and views on Flathead Lake. Grab your paddleboard, put your boat in the water in Somers, fish for trout, hike Wild Horse Island, or wade into the warm waters of "The Shallows" near Bigfork, Montana.

Although there is a fair amount of private property around the perimeter of Flathead Lake, there still are quite a few incredible public access points for locals and visitors alike. 

These public lands around the lake include a National Wildlife Refuge on the North Shore, six Montana State Parks, and nine Certified Public Fishing Access Points.

Born of a receding glacier 2,500 feet deep at the end of the Pleistocene Epoch 10,000 years ago, Whitefish Lake is now a regional draw for boating, fishing, swimming, RV camping, and countless other outdoor activities. 

As one of the more clear lakes in Montana, some of the most common lake activities on Whitefish Lake include non-motorized recreation. Kayakers and canoeists prefer the early morning when the lake is the calmest. But, as the water warms up, you'll find an increase in motorized recreation out on the water like boating, water skiing, tubing, and fishing. 

Whitefish Lake has two public boat launches for if you're planning on bringing your own boat. If you aren't planning on launching your own watercraft, boat rentals are available. 

However, if you do launch your own boat, keep in mind, decontamination of your watercraft must be performed prior to launching in Whitefish Lake. This requirement has been put into place in order to prevent the spread of aquatic invasive species within lakes in Montana.

Tally Lake

Rumored to be the second deepest of lakes in Montana, Tally Lake is a local favorite for its warm waters. 

Tally Lake is fed from water from upstream Star Meadows, a large wetland which creates a tannic acid tint to the water. The water is perfectly clean and nice, but the dark coloration makes the water of Tally Lake darker than other lakes in the area. 

Due to this darker coloration, this increases the absorption of light within the water. Tally Lake, Montana is substantially warmer than most lakes in the area. By comparison, Tally Lake has an average water temperature of 70 degrees Fahrenheit, whereas Flathead Lake's water temperature averages at 65 degrees Fahrenheit.

st mary lakeSt. Mary Lake

Located on the east side of Glacier National Park along the Going-to-the-Sun Road, St. Mary Lake is an absolute must when visiting lakes in Montana. 

This 10-mile long lake provides wonderful opportunities for wildlife viewing. Elk, mule deer, and both grizzly and black bears have been spotted along or near St. Mary Lake. 

Personal motorized and non-motorized watercrafts are allowed on St. Mary Lake with public boat launch past Going-to-the-Sun at certain times of year. For more information on these dates, visit the National Park Service's website here

But, if you don't have your own personal boat or watercraft,  you can still experience St. Mary and Glacier National Park from the water! Glacier Park Boat Company provides tours of St. Mary Lake June through September. You can learn more about boat tours through Glacier Park Boat Company here.

Lake McDonald

Potentially the most iconic of all Montana lakes, ​​Lake McDonald is the largest of all glacier lakes in Montana. In fact, its size and formation are a direct result of glacial carving. 

The high peaks surrounding Lake McDonald all show evidence of the power of glaciers carving through even the hardest of rock. 

Not only was the "u-shaped" valley that Lake McDonald now sits in carved by these glaciers, smaller hanging valleys featuring gorgeous waterfalls were also carved by these same exact glaciers.

The most colorful lake in Montana, one of the most beautiful aspects that you'll notice about Lake McDonald are the colorful rocks and pebbles that shine below the crystal clear water of the lake.

After spending the day hiking through, exploring, and recreating in Glacier National Park, Lake McDonald Lodge is available to visitors looking for a place to eat, stay, or shop. Learn more about the lodge's offerings here!
