Lyons: a red-sandstone quarry town turned bluegrass home

If the pink stone walls of the University of Colorado Boulder campus look familiar, drive 15 miles north and you will meet their source. Lyons sits in the valley where the North and South St. Vrain creeks come together, and the town grew up around quarries of red Lyons sandstone. Founder Edward S. Lyons shipped the stone to Denver for flagstone sidewalks, and once the railroad reached town in the 1880s, masons used it in buildings across Colorado. CU Boulder’s “Colorado style” campus, with its red-tile roofs and pink sandstone walls, is the best-known showcase.

The two canyon roads out of town, up the North and South St. Vrain toward Rocky Mountain National Park, earned Lyons the nickname the “Double Gateway to the Rockies.” That same St. Vrain water now runs past a stage. Planet Bluegrass holds its festivals on grounds where the creek flows just feet from the music, with red rock cliffs overhead. RockyGrass returns for its 54th year in 2026, so the bluegrass roots here run deep.

If you are aiming for a festival weekend, lodging fills early, so plan ahead. For dates and the local story, start with the Town of Lyons site.
