Lake Carlos State Park Professional Review and Guide
"First a stroll by the lakeshore, then up to a prairie and scattered woods, featuring grasslands and Lake Carlos--a deep clear lake with a swimming beach. Lake Carlos State Park was established in 1936, and ever since, the main attraction has been the park’s swimming beach. Lake Carlos stretches across 3,017 acres and has a maximum of depth of 163 feet, making it one of the state’s deepest lakes.
The lake also acts as the headwaters for Long Prairie River, a stream that served as a route for native cultures and early explorers. From here, even the Twin Cities are accessible by boat, if you are willing to travel 100 miles downriver to the Crow Wing River, and on to the Mississippi River. But the park has more than the lake to offer: prairie, maple-basswood, aspen–oak forests, and even a tamarack bog."
