Comments

Overview
The Chaska Unit is one of eight units that make up the Minnesota Valley National Wildlife Refuge. It lies on the north bank of the Minnesota River in an outer Twin Cities suburb. South of the river is the Minnesota Valley State Recreation Area, Lawrence Unit. This site is part of a much larger area that has been designated as the Lower Minnesota River Valley Important Bird Area (IBA). A hiking trail passes through riverbottom forest along the bank of the Minnesota River. A point of interest is a giant plains cottonwood next to the trail large enough to be included on the printed map.

Parking
Athletic Park may be closed with a locked gate across the entrance road if there is no ball game in progress. When it is locked park in the cul-de-sac. In Riverfront Park, park at the boat launch at the end of the park road.

Hiking Trail
The Chaska Lake Trail follows an administrative road. It leads 1.7 miles from Riverfront Park at the south to Athletic Park at the north. Visitors are asked to remain on the established trails in order to protect the wildlife.
