Located in Birnamwood, Marathon County, the Mud Lake boat ramp provides public access to this 332-acre lake with a maximum depth of 15 feet. This is one of the primary launch options for the Mud Lake Wildlife Area, making it a convenient spot for kayakers, canoeists, and recreational boaters. Parking is plentiful at the site, and outhouses are located just east of the main landing for visitor convenience.
**Important notes for visitors:** Wisconsin state park sticker is required for access, with a self-pay station at the entrance. Be aware that goose droppings are common on the ramp, so watch your footing when launching. With limited alternate access options around Mud Lake, this ramp is a key entry point for the area. The calm, shallow waters make this a suitable destination for paddlers of various skill levels.
