As arboreal hunters search the depths of Redwood National and State Parks for giant trees, hidden in  plain sight is one of the most photogenic champions: the so-called Picnic Tree, an old growth monster  near the campground of Prairie Creek Redwoods State Park. It’s been featured in travel magazines and  websites, but few who pass notice it on the edge of a cozy picnic spot, steps from the Prairie Creek  Visitor Center. This massive vertical spire has sprawling roots flaring around its base like the foot of a  mastodon, shading a moss covered stone grill that adds to its prehistoric charm. Should you eat here  among the Giants, there are plenty of picnic tables, and you can work off the meal with a stroll on the  Revelation Trail—an easy, wheelchair-friendly mile that showcases more monster trees.
