The actual address is 95 Atkins Bay Drive, Phippsburg, ME 04562. If you have a navigation system that should probably be all you need but here are the highlights.
95 North to Portland (expect ~$4 in NH & ME tolls, EZpass/Fastlane work if you have those and NH has two new high-speed lanes that work with the passes)
take Exit 44, Portland onto 295 North
take Exit 28: Route 1 Bath, Brunswick
(Note: Route 1 takes a hard left turn at a light after a mile or so! )
Follow Rt 1 to the 2nd Bath Exit: High Street / 209 Phippsburg
Follow 209 South for 6.8 Miles (look for a small sign 1774 Inn & Parker Head Road)
Left onto Parker Head Road, right across from Irving Gas Station
Continue about 4 miles on Parker Head Road
Take a Left onto Cox Head Road (it’s a dirt road marked with a Jersey Barrier’s with paintings on them. You will also see a bank of mailboxes)
2nd Right onto Atkins Bay Drive (it’s a bit hidden)
Continue up Atkins Bay Drive, a small dirt road.
At a 3-way fork continue straight up a VERY steep hill.
There is a circular drive at the top of the Hill at our house.
