Okay, I'm prejudiced, I love the California Redwoods and Henry Cowell has to be one of my favorite places to visit. Aside from the loop trail that introduces everyone to the Old Growth Redwoods, there are three other sides to the part ... the Sand Hills, the Riparian (River) and the Grasslands. You see the grasslands or meadow when you drive towards the Visitors Center and, if you're lucky, you may spot deer, a coyote, or some of the many birds in the park (owls included). The Riparian area runs along the San Lorenzo River and there you may spot Steelhead, ducks and other inhabitants of this wetland area ... not to mention the river is a great spot to sit and relax. Then there's the Sand Hills ... where else can you find remnants of the ocean so far from the sea? The Visitor's Center will delight the kids (and adults too) and the trails are well marked and will really give you a sense of what nature is all about. Right next door is Roaring Camp Railroad so you can park at Henry Cowell and walk to the train for a great ride up Bear Mountain or to the beach.
