-- From points South and West (e.g. Saint John or Maine) -- Take Route 1 to Route 114 (exit 211) between Sussex & Moncton. Just a few hundred meters past the east gate of Fundy National Park, you'll find Cleveland Place on your left on Main Street, in the middle of Alma village.
-- From points North and East (e.g. Moncton or Nova Scotia / PEI) -- Take Route 114 South directly into Alma!
If you have a little extra time, at the town of Riverside Albert, take Route 915 instead. It's a very scenic (mainly ocean-side) drive, takes only a few minutes longer, and meets up with 114 South just inside Alma.
Cleveland Place is on your right in the middle of Alma village.
