canadian parks - sightseeing?

Been a while since I chatted here. I've got a garmin nuvi 255 loaded
with a topo map as well as standard (free ibycus topo). I was wondering
if this thing could be used in parks with some degree of accuracy? Is
there any site or resource to get the trail information or common
attractions? I found a geocaching site but it doesn't have much at all.

One of the major parks in area is fundy national. I'm sure people in
area are aware of this one. I hope someone gotten to document them for
others?

I'd appreciate any help
Thanks
