This section of 51st Street from the main Boulder Reservoir parking area to the Eagle Trail Trailhead (which is also where 51st turns into 55th street) is a fun section of gravel with a nice downhill from the pavement to a short, punchy hill to the trailhead. You get great views over Boulder Valley Ranch to the foothills and Flatirons west and southwest of this section of road.

Since the earlier post from October 2023, several new gravel trails have been headed up to and down from the mesa. Flowy routes that are fun.
