"This was a very cool experience. But i will certainly wouldn’t recommend it to older ppl. It’s 90 minutes rowing and 90 minutes hiking.
You enjoy but consider stamina, sun when planning this adventure."

"Beautiful Freshwater Wailua River. Red dirt gets kicked up following flash floods in the evening and morning hours. Our guide said it looked like a Chocolate River due to that, today. The lookout is pretty. You can see the river and the beach."
Chelsea Merkley
"Beautifully green valley of wailua river. The word wailua means "two waters" in Hawaiian, and is an accurate name for this area surrounded by both rivers and the ocean. If you notice in the picture, two ways with two different colors ate merging into one. A good lookout and a Vista point."
