The route begins at State Route 4 as a two-lane road, and heads north to its northern terminus at Mount Reba, where it expands to make way for the Bear Valley Mountain Ski Resort parking lot.

Because SR 207 is the only way to access the ski resort, the state highway has more traffic during winter than when it is not snowing in the mountains.

Winter traffic to SR 207 and the ski resort may be further exacerbated due to the fact that the segment of SR 4 through Ebbetts Pass typically closes during the winter months.
