How long does it take to drive from one end of PEI to the other end?
Well, say that you take highway 12 from Seacow Pond and you head south until highway 2 and switch from highway 2 to highway 16 at E Point rd and finally turn on Lighthouse road at the eastern most part of the island, it should take several hours.
Hope it helped. :) lol
You can drive around the perimeter of PEI in a day, but if you want to go inland and see Green Gables etc., you should plan more time. If you want to just see all the highlights of PEI, you could do it in two days (one overnight). If you want time to relax on a beach or something, give yourself more time.
