Aiea Loop Trail - Activities On Oahu Aiea, Hawaii

The Aiea Loop Trail is a popular trail with locals and tourists on Oahu. This 4.8 mile long, loop trail is considered to be easy to moderate. Expect elevation gains of around 900 feet over the course of the trail.

The trail runs along the Halawa Valley ridge with views of Oahu's southern coast. The forest here is full of lemon eucalyptus trees which give off a great smell. Much of the trees here were planted back in the 1920s. Native koa trees are found near Pu'u Uau (the high point about halfway through) as are ohi'a trees (see Lehua Blossoms And Ohia Trees for some interesting mythology on those trees). There's even a crashed B-24 bomber from 1944 that you might be able to spot.

The trail itself isn't anything difficult to navigate but the constant uphill climbs might get a little tough for some, especially smaller kids and non-hikers. There are also some area with narrow paths where a slip and fall down a slope could lead to injury so watch smaller kids here. Expect an overall hike of around 3 hours, maybe less if you move faster. The trail is easy to find at Keaiwa Heiau State Recreation Area and you'll have access to plenty of parking, picnic tables, and bathrooms near the trailhead.

Although this is a loop trail, the exit come out at a slightly different place than where you started. Just follow the road back to your car, it won't be far away. Note that montain bikes are not allowed on this trail. Dogs are allowed but must be kept on a leash at all times and you must clean up after your animal.
