Elfin Forest and Harmony Grove provide one of the best country road experiences in the coastal area of the county. There are also mile markers on these roads that can be used to verify your bike computer mileage. When you pass a mile marker, count how many pedal strokes to your next tenth of a mile on your computer. A mile later, you should pass another marker, and your computer should read exactly one mile more after turning over the same number of pedal strokes.
The descent back West down Del Dios is a thrill ride, and makes up for the earlier horrors of Rancho Santa Fe.
