Cass Lake is the tribal headquarters of the Leech Lake Band of Ojibwe, located in Cass County in north-central Minnesota at the intersection of US-2 and Highway 371. The Federal Dam area of Cass Lake is one of Minnesota's premier walleye fishing destinations. The city is surrounded by the Chippewa National Forest — 1.6 million acres of boreal lakes and trails — making it a natural stop for outdoor recreationists heading to Stump Lake, Star Island, or the Leech Lake watershed campgrounds.

Sweetest Grass has a sister location in Walker at 6838 Y Frontage Rd NW, about 25 miles south on Hwy 371. Walker has longer hours (10 AM to 9 PM) and tends to be busier during summer resort season; Cass Lake is typically faster for local and highway travelers. For US-2 corridor travelers between Bemidji (25 miles west) and Grand Rapids (45 miles east), Cass Lake is a convenient tribal dispensary stop with no state tax.
