Beaver Lodge Trail
Shhhhh... Walk quietly up to the wetland pond, and if it is early evening or morning, you may see the industrious beaver at work. Sit on the bench, read the sign about beavers, and watch the lodge. You never know what you may see.

This lake was named after Alice O'Brien who donated the first 180 acres of the park in memory of her father, William. It is spring-fed on the north end of the lake, so it stays beautiful all summer long.

Stop at the park office and borrow some fishing gear! You don't even need a fishing license to fish in Minnesota State Parks. Fish for white bass, panfish, small and large-mouth bass and see what you can catch.
