Locals call Lake McConaughy "Big Mac." With 100 miles of shoreline, it's an apt nickname. Combined, the neighboring Lake McConaughy and Lake Ogallala State Recreation Areas offer more than 30,000 acres of water. So jump in! Boat, fish, swim or wind-surf. Hang out on shore for sunshine, sandcastle-building and camping. Head into town for Front Street and the Cowboy Museum. The Wild West show and saloon dining make an entertaining break from the lake.
