Mountain bike trail conditions · Bay Area, CA
Trails are dry, excuses aren't.
Redwood Regional Park is a mountain bike network in the Bay Area, CA area. It rides on mixed drainage soil across rolling, forested terrain — the combination that decides how the dirt holds up after rain and how quickly it bounces back.
Redwood Regional Park’s drying behavior comes down to what Loam measures for this exact location:
This network sits on mixed or loamy soil — a blend of particle sizes that balances water retention with reasonable drainage. Drying time falls between sandy and clay soils, typically a day or two after significant rain.
Heavy tree cover shields trails from sun and wind, slowing evaporation after rain. Forested trails stay shaded and cool — great in summer heat, but they take longer to dry than open terrain, and drip from leaves can keep things damp even after dry days.
Rolling terrain drains reasonably well and tends to be forgiving in variable conditions — enough gradient to shed water without the consequences of steeper ground.
Slopes here are predominantly west-facing, with about 2% rock fragment content in the soil — a factor in how fast the surface sheds water and dries.

Redwood Regional Park sits on mixed drainage ground (Loam). This network sits on mixed or loamy soil — a blend of particle sizes that balances water retention with reasonable drainage. Drying time falls between sandy and clay soils, typically a day or two after significant rain.
On its mixed drainage soil, Redwood Regional Park typically takes about a day or two to dry after significant rain, and its rolling terrain helps shed water. Heavy tree cover slows drying further.
Yes — Redwood Regional Park 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.
