We are novice hikers in our late 20's, this trail is completely worth the 15k trek, but it is a long 15k, we found the 5k-10k point the most demanding, bring PLENTY of water as there are no fountains or such! also the part of this trail which takes you down to the beach and across (see map) is no longer, it deadends and you must return up the hill! the views when you hit the coast are something else, but also don't dismiss the forest!
