Camp Mintahama opened in 1946, when Camp Nicagaha, a coed camp, was shut down to make room for the new highway 80. The Girl Scouts bought new land and relocated and built their own "Girl Scout Camp." It is 180 acres and is the pride of the Girl Scout Council of the Ozark Area. It is located 9 miles south of Joplin, Missouri. The camp was built, but it had no name. An essay contest was held to name the camp.

Camp Mintahama has a 12 acre lake, hiking trails, program areas and an island. Canoes, sailboats and paddleboats, archery and other program equipment are available for use with proper training and certifications.

There are two cabin units, two platform tent units, and one treehouse unit. Each unit houses approximately 28 people. Each unit is also complete with a fire ring, running water, picnic tables, unit shelter, and latrines. Also available is a large dining hall, shower house, log cabin and an in-ground pool (June-August).

Camp Mintahama is the home of GSCOA's resident camp for seven weeks in the summer. Camp Mintahama is an American Camping Association accredited camp facility.
