Trail Overview

Boulder FSR is part of a series of FSR roads we linked together to get us from the Christian Valley over the mountains to the Granby Valley. The road is less maintained than a main FSR, so expect lots of ruts, pot holes, and wash board. Each spring could bring new road conditions due to spring melt. The views are amazing up here!
