The call for help came in around 3:30 p.m. from the Point Road in Otis.
When first responders arrived at the camp near Beech Hill Pond, they say the structure was fully involved with flames shooting out the windows.
Luckily the cabin was unoccupied at the time.
Several departments responded to the scene and worked together to get the fire under control.
"Water wasn't an issue," said Deputy Chief Karen Murray with the Mariaville Fire Department. "I drove the engine right up, straight into the structure and Ellsworth was able to get their portable pump going. They were able to pump me water so we had continuous water right from the Beech Hill Pond so we didn't have any trouble with that at all. "
Crews from Mariaville, Ellsworth, Aurora, Waltham and the Maine Forest Service helped extinguish the fire.
The camp itself is a total loss, but there are no reports of any injuries.
No word yet on what caused the fire.
