I recently traveled to British Columbia with a group of friends to do some mountain biking in the area. We flew into Vancouver (there's a direct flight from DFW to YVR) and drove north to Squamish and rode the diamond head area for a couple of days before driving further north to Whistler. While in Whistler we rode the bike park one day, the trails on the Blackcomb side another day, and on the last ride day we hired a float plane to take five of us into the Chilcotin Mountains for a day of back country riding.
If you're a mountain bike enthusiast, this region is a bucket list place. The mountain trails and relatively low altitude make for some of the best riding that I have ever experienced. On this trip, I used my Specialized Enduro 29er and it worked great! From the long road climbs, to the double black diamond trails at the Whistler bike park the bike never missed a beat.
