Montana sits within the Rocky Mountains regions and is known for its contrasting terrain, which is made up of flatlands in the east and towering mountains in the west. It is the USA’s fourth largest state and one of its most sparsely populated as a result of its landscapes. Still, it is a beautiful state that is famed for its big blue skies, hence its nickname the ‘Big Sky Country’.

Montana is home to three major tourist destinations; the Glacier National Park, Yellowstone National Park and the Little Bighorn Battlefield National Monument. Combined these three sites attract millions of tourists each year. The rich river valleys are also a major draw, as are its massive amount of lakes. In fact, the state is home to over 3,000 lakes and reservoirs. Of those, these are the 15 best lakes in Montana.

1. Lake McDonald; Flathead County

Lake McDonald can be found at the west end of the national park at an elevation of 961 metres above sea level. The scenic Going-to-the-Sun Road skirts the east side of the lake, while one of the Lake McDonald Valley Trails sits along its west shoreline.

There are four camping grounds within the Apgar Visitor Center, which is on the very south end of the lake. Apart from fishing and scenic boat tours, no activities are offered, with the magnificent scenery being the main draw of the glacier lake.

Like many of the other best lakes in Montana, Bowman Lake sits within the Glacier National Park. It is one of the lesser visited lake’s in the park due to its remote area, which is part of its charm.

There is a small campground at the south tip of the lake that is quiet and uncrowded. Day trippers can also use the campground as a spot for a picnic lunch or for access to the lake for going fishing.

Bowman Lake is accessible by an unpaved road from the small town of Polebridge. Once here, there are numerous hiking trials that run along the shore of the lake as well as to other nearby bodies of water.

Iceberg Lake

The spectacular scenery is reason enough to visit Iceberg Lake, which lies in the Glacier National Park at an elevation of 1,857 metres. The Iceberg Peak towers over 900 metres above the lake, as does the Mount Wilbur and the Continental Divide.

Iceberg Lake is only accessible by hiking along the 15.6 kilometre long Iceberg Lake Trailhead. The trail starts at the Swiftcurrent Auto Camp Historic District, which is a built-up area of the national park.

Because of the towering mountains that encircle the lake, it gets very little sunlight. This results in ice and snow building up on the water and the surrounding cliff walls, with the result being picture perfect scenery.

15. Fort Peck Lake; Valley, Petroleum, Fergus, Garfield, Phillips & McCone Counties
