This unpaved "road" — really, just a nice walking trail — used to be an access point for the Moanalua Ridge Trail, a route up to the "backside" of the Haiku Stairs. That route is now closed and people who've tried to sneak through have gotten tickets, so it's better not to risk it. The early part of the road is interesting in and of itself, though, thanks to interpretive signs that point out natural history and relics.

Right about here you'll see a side trail on your left. This is the access route for Kalauao Falls, but be warned that the 'Aeia Ridge and Loop trails generally make a much nicer — and less muddy — adventure.

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.

The Crouching Lion summit is a short but steep incline that offers breathtaking views of Kahana Bay. If it has rained recently, I don’t recommend hiking the Crouching Lion Trail. Most of the trail consists of mud and clay that gets extremely slippery when wet and can make this trail very dangerous.

Lower Waimano Trail and Upper Waimano Trail run parallel to each other and meet again after the first section, so actually it's up to you, which trail you prefer. The biggest advantage of the Lower Waimano Trail is, that it's a little further away from the street, and you don't have to hike along a fence. If you're hiking the loop, it makes sense to use both trails in one direction each.

Widely known for the infamous attack on Pearl Harbor, you get a nice view of exactly that location from this spot along ʻAiea Loop Trail.

Located next to the parking lot along ʻAiea Hights Drive, you will find the trailhead for the popular ʻAiea Loop Trail. The trailhead can also be used for Kalauao Falls Loop Trail, which has a connection after less than .5 miles.
