My brother came out west and we did some travelling together. Here's a map of trip number 1, from Vancouver into the BC Okanagan Valley. We stayed in Oliver with some relatives, went skiing at Apex, and then flew back to Van from Kelowna.
My cousin who grew up in the valley has a website about Okanagan Wine, which is one of the big things the region is known for. We got to do a little bit of tasting at dinner.
