Pebroke is north of Ottawa. You don't need to go that far though. Bancroft (south of Algonquin park) trails are now groomed and open too. They have over three feet of snow there. I was riding yesterday!!
All open. We were riding all day Sunday in the area. As long as you stick to the railroad bed you'll be fine. We rode from Fenelon Falls to Kinmount and headed toward Whitney. The trails were a little bumpy, but they are grooming now (as far as I know). A friend of mine has a cottage in Bancroft (we stopped in for a peek) and we rode to Whitney and Barry's Bay and all the trails were great. Over three feet of snow easily.
