Start at the Edison "towers" and follow the fireroad climb you came up for a few yards only, than bear left into Dogtag trailhead. The upper part (Top-Dog) is slightly steeper, but still enjoyable to ride and offers plenty of variants. The lower part of Dogtag is very smooth and full of flow, not too hazardous! Great combo with the Tapia Canyon Rd Singletrack
combo (SideWinder trail, G-Out trail
, Dogtag, Kona singetrack).
