We enjoyed the 0.9 mile walk on the public access path to St. Regis Beach, then looping counterclockwise back up the paved path out the next resort and golf course road, total of 2.5 miles. Nice mountain backdrop.
From Ke'e Beach at the end of the highway past Princeville, we hiked slippery Kalalau Trail to rugged Hanakapiai Falls 8.8 miles with 2200 feet cumulative gain, very scenic for adventurous souls; but bring good hiking shoes, poles, water shoes for several crossings, and much drinking water, like 3 liters. Beautiful tropical hike, my fourth visit.
