Redwood National and State Parks run about 50 miles up US 101 from Orick to Crescent City and hold about 35% of the world's remaining old-growth redwood forest. At Fern Canyon you walk through ankle- to knee-deep water between fern-covered walls about 30 feet high. From May 15 to September 15 you need a vehicle reservation to drive there. The tallest known tree, 379 feet, is off trail, and the park asks you not to go looking for it. Reserve a spot at the Tall Trees Grove trailhead online instead. The trail drops about 800 feet in its first 1.5 miles, and the climb back out is long.
