Mountain bike trail conditions · Bay Area, CA
Trails are dry, excuses aren't.
Sitting in the Bay Area region of CA, Crockett Hills is defined by its slow-draining soil and flat, exposed ground. Those traits, more than the forecast alone, drive when this network is actually rideable.
Crockett Hills’s drying behavior comes down to what Loam measures for this exact location:
Dense clay soils compact easily and hold moisture long after rain. When wet, clay trails turn slick and rut easily — damage that can take weeks to heal. These networks need the most drying time before they’re worth riding.
Open terrain gets direct sun and wind from all sides, which speeds evaporation significantly. Exposed trails are usually the fastest to rebound after rain — a bright, breezy afternoon can make a big difference.
Flat trails have nowhere for water to go. Low spots and natural depressions collect standing water and mud that lingers well after the rain stops, so these networks often stay wet longer than the weather alone suggests.
Slopes here are predominantly southeast-facing — a factor in how fast the surface sheds water and dries.

On its slow-draining soil, Crockett Hills typically takes several days, sometimes longer, to recover after meaningful rain, and its flat terrain can hold water longer in low spots.
Yes — Crockett Hills is in a maritime snow climate, so winter riding can be limited by snowpack or freeze-thaw. Loam flags a FROZEN state when the ground is snow-covered or frozen.
