Cycling Newfoundland
 

Which is the better route away from Argentia, Highway 100 or the more southern route of Highway 91 and then 90? Are there any campgrounds on the southern route?

You won't get many replys here but you may want to contact these folks for suggestions. http://bnl.nf.ca/bnl/

You might also try these folks, who I l know have cycled the island coast to coast.
