"We spent a month on Oahu, did a lot of different things including hiking different trails. I can say for sure; the Aiea Loop Trail is one of the best trails I ever been to. It is so great we visited it 4 times within a month we’ve been in Oahu.

The trail is 4.8 miles and will take you about 2 hours. I was wearing sandals all the time, but it might get muddy, so hiking shoes are nice to have. You will walk through different forests, including eucalyptus trees area and the smell just great. It’s very often raining there at least at some part of the trail, sometimes moderate rain, sometimes just drizzle. We never felt cold/wet due to sun.

The scenery are great, there is no way to describe it.

In addition, there is ALWAYS a RAINBOW somewhere on the trail.
We were with kids (13 and 16 yo) and they did just fine. We saw a lot of people with younger kids, but not sure they did a full loop.

Aiea Loop Trail is a really great way to spend 2 hours in the rainforest. Highly recommended!"

"Great trail just outside of Honolulu. Moderately steep in sections but overall not too strenuous. Parking was easy on a Saturday afternoon."

Dylan Neill

"Its is a very nice trail, you can smell eucalyptus, it up and down, so many trees along the trail. It more than 5miles and two hours to hike."
