Speaking as a one time tourist to Vancouver, our highlights were:
Stanley Park is probably a must for first time visitors (eg GC58E9)
Punta del Este (GCMYTN) on Buntzen Lake. Cache too tough for kids, but there are a few others in the area.
Drive from Vancouver to Squamish (eg GCJ2RC, GCQ8FC, GCKECG)
Coincidentally enough, we will be heading to Vancouver (and possibly Vancouver Island) in two weeks. I've been scanning geocaching google maps and we can't find a trail or park with a high density of caches. We're looking for a place where you can park the car and spend half a day or a full day finding ~15 caches. Any suggestions of this type?
