Not a trail for beginners. Sturdy shoes are necessary. But they don't have to be alpine hiking boots. Trail running shoes are recommended - not waterproof ones, but ones that dry quickly and have a good, non-slip sole.

This stunning lookout is just off the road. you get there by driving winding Highway 550, AKA the Kuhio Highway. The lookout provides a dichotomy of Kauai's dramatic land- and seascapes: On one side, you have precipitous sea cliffs plunging into the ocean. On the other, the lush greenery of the Kalalau Valley.

Unfortunately, everything was covered in fog when we visited. But the view must be great. We were there around lunchtime. Earlier would have been better.

Although it's well-maintained, this trail is almost never level, and it can get slippery fast when wet. Keep an eye out for wild goats, many native plant species, and of course amazing views out over the water as you hike. Also, keep in mind that if you want to hike all the way to Kalalau Beach (or simply beyond Hanakapi'ai Valley), you need an overnight permit. Hanakapi'ai Beach is the usual turnaround point for day hikers.

Puʻu O Kila Lookout sits at the end of Highway 550 in Kokee State Park. If there are no clouds, riders can enjoy one of the very best views on Kauai. The view is panoramic and looks down into the Kalalau Valley. Here can also be seen the Alakai Swamp, which is the highest-altitude swamp in the world. Theo Kalalau Valley is home to the wettest place on earth, which ends at the summit of Waialeale.

The rewarding payoff for runners able to conquer the route to Hanakapi'ai Falls is its stunning 300-foot cascade. For an elevated perspective, continue scrambling up the boulder field to a mossy cliffside platform, 100 feet up, tucked left of the waterfall. The view of the thundering waters makes a tough run worthwhile.
