The Wa'ahila Ridge trail is a state trail so it's well traveled and easy to follow with a clear path and signs, perfect for travelers and vacationers. There are a few steep areas and some rock scrambling, but no big deal. You can't go on a hike and have NO challenges...At a point the Ridge will split so stay to the right to reach the Wa'ahila Summit ridge line. If you wish to continue and crest the summit ridge you can make your way to the well known Mount Olympus, but this trail is very narrow and somewhat overgrown so it's up to you if you wish to make the extra hike to the Olympus summit...if you choose to do this second part of the hike watch your footing...this no longer is a state run trail and you're on your own.
