The national spotlight is being cast on the park again this month with the Redwood Empire featured in National Geographic magazine. The centerpiece is a fold-out photograph of one of the park's giants, the Iluvatar Tree, the world's third-largest coast redwood at 20 1/2 feet in diameter and 320 feet tall…

Of the trails that provide access to old-growth in California, the James Irvine Loop is one of the best. This loop is a 7.5-mile round trip that provides a route past a succession of giants. It's easy enough that most anybody can simply walk a half mile and back to get a feel for an ancient forest. It's long enough that the entire loop delivers a sense of discovery and awe with each grove, and the good, clean feeling that comes with hiking a few hours in a pristine landscape.

This trip can change how you feel about things for a long time. Big trees can do that.
