This hike you have to get one of fifty daily permits to take - we scored one of them on the only day we could have.

Its considered a rigorous hike of four miles, round-trip but mostly because it drops 600 feet to the river bank. We thought walking down-trail was hard until we had to climb out.

Underneath a canopy of the tallest trees in the world you feel pretty insignificant.

These trees grow so well because they are constantly watered - if not by rain, by the ever-present fogs.
