A long but very pretty drive, (from SoCal), Jade Cove is worth the trip. Don't attempt this if you are not in pretty good shape, the hike and entry/exit are tough. Diving through a pass-thru, with walls of solid Jade, is a heck of a payoff! Fair warning, just because it's green rock doesn't mean it's Jade. There is also green and black serpentine everywhere, that is what most of the green rock is.
