Since we're placing it in the spring, before the foliage has
bloomed, we don't know if poison ivy will be a problem in the
summer. But this time of year black flies definitely are - you'll
want to bring bug juice.
The Ralph Hill Conservation Area is maintained by the Sudbury
Valley Trustees in coordination with the Town of Billerica. It's a
hidden treasure. At the
Sudbury Valley Trustees website there is a trail map available
for download.
The main entrance to the trail system, by the kiosk, is
currently under repair. But you can clambor over the bales of hay
to get in. Or you can come in from the new BMX parking lot, see the
Parking waypoint.
You'll be looking for a 7.62 mm ammo can. Happy Hunting!
