Helvetia is located in Randolph County south of Buckhannon and southwest of Elkins. If you use a mapping program or GPS, it is recommended to set "Helvetia, WV" as the destination, not the Zip Code. (When the Zip Code is used, some systems put the destination at the center of the area covered by the Zip Code rather than at the desired town.)
Note that cell phones do not work in Helvetia although there are places where they can be used within a short drive.
Andrew Zimmern, host of Bizarre Foods on the Travel Channel, tells of his difficulties in getting to Helvetia.
