I used to hike a lot and really enjoyed it. It's a great way to exercize and get out in nature.
Yes, I like it as well. It's better than just walking in an urban area
Definatly. I don't mind walking in the sububs, but anywhere that has a lot of exhaust fumes makes me fell ill. 
In the UK they use the word walking for both walking and hiking
Oh yeah? I guess we do too here in the US. Although, I think hiking, to me at least, needs to involve some type of trail and dificult terrain. 
Yeah, most people I know when they say hiking it involves woods on paths
I can see that. I know if someone asks me to go out walking, I can assume that we will be on a paved surface. For me, that's not nearly as exciting as hiking in the woods.
In Australia they use the word bushwalking for hiking. There's even a bush walkers club
Ha! Really? That's pretty cool. I could definatly get onboard in a bush walking club. I bet it's a lot of fun.
New Zealand calls hiking tramping. I find that name entertaining!
Me too!!
