Parking and trail access is from along Corn Hill Lane, off Union
St. in Marshfield.
The roadside has no shoulders to park, but it's a dead end with
only a few widely spaced houses beyond the trailhead. There are
actually two trailheads on the road; the first one is the more
interesting & less wet.
All the forest paths are narrow & winding. There are scattered
patches of poison ivy near the paths; be wary. There are also
narrow boardwalks constructed across wet areas. They are well
intentioned, but somewhat risky; built in 1992, and now in a state
of disrepair & decomposition.
Cache is a 5x7 lock n lock in a camo bag. The trek to the
cache is .75 miles, and drops 100 feet as you approach the river.
The elevation change is gradual, and not a hardship, but you
will breathe a little heavier on the return trip.
