As a waterfall it is about 5/10, as a hike about 3/10, ( extremely muddy when we did it), but for forest birdlife, 8/10.

This viewpoint gives you great views of the ruggedly beautiful Halawa Valley to your south. The road running through it is Hawaii's H3 interstate highway. Yes, you read that correctly—it's technically considered an interstate, even though it only traverses the one island. If conditions allow you can even see all the way to the city of Honolulu, also to your south.

This is one of many points along the 'Aiea Ridge Trail (which transects the 'Aiea Loop) that give a great viewpoint over Pearl Harbor. It's an evocative place, where you can easily imagine what it might have been like to witness the Japanese attack on the harbor that triggered the United States' entrance into World War II.

Nice flat area at the top of the ridge, with excellent 360 degree views. Strongly recommend against continuing to the Manamana trail - it is closed for a good reason.

Great place for a picnic when it's dry. Turn back here - the route that continues up the ridge is poorly maintained and overgrown.

On this point of the trail you are on the top of a cliff with the Halawa Valley and the highway below. The highway adds a certain element to the view by providing a reference point to show just how big the valley actually is.

At the top of Alea Hights Drive there is a nice view of Pearl Harbor that gives you a good reference about how high up in the hills you are.

If you do like climbing and getting in some serious vert before heading back to the hotel for blended drinks, you can head up Onikiniki Place, Kaahele Street, or any street that heads into the hills!
