Why Tilden dries this way
Terrain & soilTilden is a mountain bike network in the Bay Area region of CA, riding on loam soil that drains well over terrain that sheds water and dries quickly. What really sets the timing here is how quickly that ground gives back a firm, dry surface, not what the day’s forecast says. The terrain here is rolling (a 7.4° average grade at 1,230 ft) and drains steadily rather than pooling, while the WSW-facing aspect gets its strongest sun in the afternoon, so morning laps can stay tacky after overnight moisture. Named trails in this network include Wildcat Gorge Trail, Redwood Trail and Mineral Springs Trail.

How these factors affect drying
SoilLoam
Loam balances drainage with water retention, so it typically takes a day or two to dry after meaningful rain.
CanopyPartial 50%
A mix of sun and shade. Conditions vary across the network, with open sections drying faster than covered ones.
TerrainSheds water
Water runs off this terrain rather than pooling, which helps the surface dry out after rain.

What trails are at Tilden?
Named trails at Tilden include Quarry Path, Big Springs Trail, Wildcat Gorge Trail, Redwood Trail and Mineral Springs Trail. That is a sample of what our map data covers rather than a full inventory, and local trail counts change as networks are built out. Loam models conditions for Tilden as a whole, so the verdict on this page covers the network rather than scoring each trail separately.
What's the terrain and elevation like at Tilden?
Tilden sits at roughly 1,230 feet, faces mostly WSW, and averages a 7.4° grade with about 50% tree cover. That makes it an afternoon-sun network where mornings run tackier, and the rolling grade means it drains at a steady clip. Loam models this exact ground against live weather rather than using one regional forecast.
When is the best time of year to ride Tilden?
There is no real off-season at Tilden: snow rarely interferes, so good days come down to rain and how fast the dirt dries. The live verdict above reflects today.
