Off to BC next week, have already booked some time with Bear Back Riding, but also having a look for half a day on Vancouver Island. Have to keep the rides short, as also with the OH. She will end up horse riding or wine tasting.

Could anyone recommend any guides on Vancouver Island?

The Riding Fool hostel is one of the islands most well known biker accommodations. They link these guys:
island mountain rides
I have no direct experience with them though.

See you soon!

Ah brilliant. Will take a look at these guys. Very much looking forward to my days riding in Whistler.

We used Martin from island mountain rides as mentioned above. He was brilliant. Taylor ed the days out perfectly and it was more like riding with one of your mates. Would highly recommend.

Lucky bastard.
I love the island. Make sure you get to Tofino!

Another shout for Martin at Island Mountain Guides, had a brilliant day riding around Cumberland with those guys.
