Trails in the Redwood National and State Parks are closed to dogs. At the Ranger Station, though, the ranger kindly pointed out that although Cal-Barrel Road was only open for cars a couple of weeks per year, the fact that cars were sometimes allowed on it meant that dogs could walk on it year-round. We took advantage of that, and had a nice hike there. The bonus was that the road wandered through some really nice trees, and I took this reflection in one of the small puddles along the road..
