According to the Minnesota Department of Natural Resources website, the Hubbard County boat ramp is located on the southeastern shore of Big Mantrap Lake, near the town of Park Rapids. It is a concrete boat ramp with a width of 12 feet, suitable for launching most small to medium-sized watercraft.

Big Mantrap Lake is a popular destination for fishing and boating, and the lake is home to a variety of fish species including walleye, northern pike, largemouth bass, and panfish. Motorized watercraft are permitted on the lake, but there are restrictions on boat speed and noise levels to protect the natural environment and ensure the safety of other lake users.

Overall, the Hubbard County boat ramp appears to be a well-maintained and accessible facility that provides easy access to the beautiful waters of Big Mantrap Lake in Minnesota.
