Scottish Fire and Rescue Service (SFRS) was alerted to the fire in the Kilpatrick Hills, near Old Kilpatrick at around 2.13pm on Thursday.
One fire engine was initially sent to the scene but crews called for an additional three appliances after assessing the blaze.
Firefighters worked to get the blaze under control but were forced to leave the scene due to loss of light.
Crews are set to revisit the site first thing on Friday morning.
