Glen Brook begins on the southern side of Lee Mountain in Salem Township, Luzerne County. It flows east-southeast for a short distance before turning southwest and flowing into a valley. After approximately a mile, it enters Briar Creek Township, Columbia County and receives an unnamed tributary. It then turns south-southeast for several tenths of a mile, passing the Glen Brook Number Four Dam. Near the border between Columbia County and Luzerne County, the stream turns southwest and flows into Foundryville, where it makes a sharp turn east and then west, entering Berwick. In Berwick, it turns west-northwest and then southwest, roughly following the northern border of the borough. After several tenths of a mile, the stream leaves Berwick and returns to Briar Creek Township. A short distance later, it reaches its confluence with East Branch Briar Creek.
