The Cuyuna Lakes State Trail is a 7-mile paved trail beginning at the Croft Historic Mine Museum just north of Crosby and travelling to Ironton and Riverton through the Cuyuna Country Recreation Area with its abandoned mines, deep, clear lakes and pine forests. The recreational area contains six natural lakes and 15 deep mine lakes providing a system of canoe and kayaking routes with exceptionally clean waters good for trout fishing and scuba diving. The Cuyuna Lakes State Trail is groomed for fat tire biking and walking in the winter.
Park on the end of 8th St NE or on the Portsmouth parking area on the west side of State Hwy 6 just north of Crosby. Parking is also available in Ironton near the water tower and at the Riverton trail termination on County Rd 128.
The Cuyuna Lakes State Trail connects the individual clusters of the Cuyuna mountain bike trails in the Cuyuna Country State Recreational Area.
