I believe free admission is Canadian residents only, but I might be wrong
we go to the maritimes everyyear, mid august till the end of September. we drive from Ontario and first stop is fredericton nb. coming from florida, you can cross at st Stephen/Calais(me) or Woodstock(bangor me)
lots to see and do everywhere.
if cross at st Stephen, go to st Andrews, Kiwanis club campground right on the water. plan a day or two in Fredericton, hartt island campground highly recommended and check out the farmers market in downtown f'ton
head towards fundy national park and the Hopewell rocks, there's a nice cg just west of the Hopewell rocks. get lobster and bakery stuff in alma, just east of the national park.
going past Moncton head to nova scotia and to Halifax or up to cape Breton and the cabot trail. don't try the cabot trail in a mh with a toad unless you have really GOOD brakes
from nova scotia take the ferry to pei for a few days, and take the bridge back to nb
that's a nice round trip, two weeks is minimal
lots of camping everywhere, walmart stores welcome you everywhere. reservations are recommended for the weekends in august and sept 1(labourday weekend), after that Its pretty quiet everywhere
