Beautiful loop from Prairie Creek Visitor Center down to the beach along a ridge, then about a mile along the beach before heading back through Fern Canyon and up a couple of small river valleys and a saddle. From the visitor center follow the James Irvine trail for about 3/4 mile until the Miner's Ridge trail. It begins quite straight and level, alongside a small stream and through a relatively sunny valley with no large redwoods at first, not until a mile or so when it turns up a side canyon and starts to climb the hillside. Then the trees grow large, the sunlight decreases and the surroundings take on a more mysterious aspect - this is a particularly dense, Tolkienesque part of the forest. The path winds around side canyons and up some steep slopes then after about 2 miles leaves the valley and crosses a more open area, later descending into another valley and finally meeting the scenic parkway. The scenery is monotonous in some ways but always impressive. You can walk along the beach or take the inland dirt road for about a mile north until you hit the trailhead for Fern Canyon/James Irvine trail.
