A grassy plain slopes up to the canyon. An easy warmup? Baylor Canyon has been discharging granite stones for eons and many have been set up as jagged water bars so riders aren't going to find a flow trail here.
Ultra-chunky in spots. Expect lots of hike-a-bike up and some down, too. Above the first switchback there are a series of shelves where the tread is granite sand (grus). These are pleasant to ride but always end in a cascade of stones or ledges.
Descend with care. The smaller embedded stones can grab your front wheel sending you over the bars. Overall the trail is very tough tires and sealant is essential. I punctured a Purgatory Grid on a water bar riding slow (tire, not tube), first time ever for this model tire. Fortunately, I always carry tire plugs and extra sealant.
With a 1,500-foot ascent, keep in mind that weather conditions may be very different at the pass. Be prepared.
This trail can also be ridden as a downhill-only with a shuttle, of course.
