Over the tracked history, Valley Forge National Historical Park has been rideable on 9 of the last 10 days, and too wet to ride on 1. Daily trail markers are representative daytime outlooks. Weather is one input. The rideability verdict also accounts for soil, terrain, canopy, and drying time.

Why Valley Forge National Historical Park dries this way

Valley Forge National Historical Park sits in the Lancaster & Lebanon, PA area, on loam soil that drains well over terrain that holds water and dries slowly. Heavy tree cover holds the damp in, so it stays wet longer than the sky overhead would suggest. Whether it’s worth riding comes down to how that ground sheds and holds water after rain. That’s exactly what Loam tracks, hour by hour. The W-facing aspect gets its strongest sun in the afternoon, so morning laps can stay tacky after overnight moisture, and the nearly flat terrain, about a 0.7° average grade at 115 ft, lets water sit, so the flat stretches are the last to firm up.

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.

CanopyDense 89%

Heavy tree cover shades the soil and blocks wind, so these trails dry slowly and can hold morning damp even after dry days.

TerrainHolds water

Water tends to pool and linger here rather than running off, so the surface can stay damp well after the weather clears.
