I think one thing you should know is that it rains A LOT. That can be hard to believe in the summer time, but this is a temperate rain forest. It makes for very gray skies from fall until spring.
As far as what to do/see - there are all skill levels of hikes around. Cultus Lake is beautiful (albiet busy in the summer) and has waterslides. There are waterslides right on the Highway, but they aren't as good. Bridal Falls is pretty and right off HWY 1. Chilliwack has quite a bit of Agri-tourism (agricultural tourism), if you are interested in that sort of thing. There are lots of you-pick berry farms. Minter Gardens has lovely flowers, Yarrow has many pottery studios...
The Fraser Valley is really big - the stuff I listed is only in the Aggassiz/Chilliwack area. That's only the very beginning. Well, or even before that Hope is a nice small town, IMO.
What exactly are you interested in? I could maybe be more specific. There are municipal websites (
Chilliwack's for example) that will give you information as well...
