Eureka was known as the Tobacco Plains and was originally home to the Kootenai Indians. The area offers scenic treasures tucked away in Montana's northwest corner. Tobacco River Campground is located adjacent to the Tobacco River in a natural forested area. It is also in the vicinity of 90-mile-long Lake Koocanusa and The Hoodoos, a limestone formation found in an adjoining bay off the lake. Ten Lakes Scenic Area treats visitors to mountain drives, pristine lakes and abundant fishing.
