The Kalalau trail to Hanakapiai beach is one of the most beautiful hikes in the world. It starts off at Ke’e beach, and you need advance reservations for parking. I’ve done this hike about 7 times and it never gets old. The views of the Napali Coast line are unforgettable. You can hike a little more than 2 miles to Hanakapaia beach, or keep going a few more miles to the Hanakapiai falls or even more if you have a hiking permit into Kalalau Valley (we attempted to backpack there a few years ago but part of the trail was washed out). The trail will be harder if it is wet and slippery – so be careful! A lot of locals do this barefoot, I tried it and it was great to soak up that Hawaiian mud and negative ions.
Length: 4.5 miles if you go to Hanakapaiai Beach
Good for kids: Yes, just be careful as you get to the stream at Hanakapiai Beach, do not cross with kids. You can walk along the near side of the stream to the beach area.

Notes: Ke’e Beach and the trailhead for this hike is part of Hāʻena State Park. Don’t forget parking reservations – you can make it a few weeks in advance here. Plan to swim at Ke’e beach after the hike, it is so beautiful and good for kids as there is a reef barrier on the outside.
