The Tafoni Trail (Lower) starts in a wide clearing where the Tafoni Trail (Upper)
and Fir Trail (Upper)
form a junction.
Start off riding a short downhill and keep an eye out for the right-hand (short out-and-back) detour off Tafoni Trail. Hike-your-bike on the footpath to see the ancient sandstone formations. This grouping of large sandstone boulders is rare and fragile, having slowly eroded over the years. An observation deck was built to give a better view and to help protect the formations. Retrace your steps back to the main Tafoni Trail and head right (northeast).
From here it's a lot of downhill, which can be tricky in the fall/winter time after it rains. The trail here is shadowed by oaks and firs. The trail ends at the junction of El Corte de Madera Creek Trail
