A quick trailhead check
Check official closures before setting out. At the trailhead, start with a short check of the first section, then continue only if the ground stays firm.
- Press a shoe into the tread. Firm ground should hold its shape. A dry crust can hide soft soil underneath; check whether the tread gives under gentle pressure rather than relying on its color.
- Check a low spot, flat corner, and shaded section, not just the first sunny stretch. Dark patches and puddle edges deserve a closer look.
- Ride a short distance only if the surface stays firm. Stop if your tires pick up sticky mud.
- Turn back when a tire or shoe leaves a groove. Riding soft tread can leave lasting damage. Do not avoid one soft patch by riding around its edge.
Damp ground can be fine. The warning sign is movement underfoot, mud that builds on the tread, or a rut that remains after you pass.
Leave soft ground to dry
If a shoe or tire leaves a rut, turn back.
Look at the sections that dry last
Low spots
Water collects in dips. A shallow puddle can have soft ground underneath it.
Flat corners
Turns and benches with little slope can drain slowly.
Shaded sections
Ground under trees gets less sun and wind than an exposed section.
Fine soil
Clay and other fine soils can stay soft below a firm-looking surface.
Watch your tires
A little damp dirt is normal. Thick mud building on the tread or a groove left behind you means the ground is too soft, even if the rest of the trail looks dry. Report what you actually found, including when and where you checked.
Conditions can change along the ride
A trail can cross open ground, dense woods, slopes, and wet low spots. The first dry section does not tell you how the whole network will ride.
Conditions can also change during the day as frozen ground thaws or more rain arrives. Check again before leaving, and choose another ride if the trail is still soft.
Sources and method
Loam estimates conditions from weather, soil, and terrain. It does not measure the trail surface directly or override an official closure. Read how the estimate works and see the published checks and their limits.
