Nice weather forecast so H and i went for a hike in a new area near Gananoque, the Marble Rock trail mentioned in the Hiking Trails of Ottawa book. Bit of a drive but well worth it. Rugged but navigation not nearly as difficult as in the description; very well signposted but trail itself not very well maintained with many downed trees, some of which looked like they had been there years and lots of garbage at the trailhead parking lot which is very small (room for only a dozen cars). Trail guide suggested lunch on the East side of No Name lake on the North looop, but it was very windy and cool on an otherwise warm fall day, so we went on a few hundred metres to the next lookout and had lunch in a sheltered spot with a view. East side of S Loop is perhaps the most scenic and rugged and would make a great out and back snowshoe in the winter.
