My wife & I hiked the 2 miles (each way) of the Kalalau Trail to Hanakapi'ai Beach. The views of the coast are spectacular and well worth the hike. However, we don't recommend the hike if it's not dry as the rocks become quite slippery. Prepare to have a workout as many of the inclines are rocky and quite steep especially at the start of the trail. Good footwear and water are musts. Take 3.5 to 4.5 hours to enjoy the stops with views that are amongst the best in Hawaii - and that's saying a lot!
