Lessor known trail that starts from Keaiwa Heiau State Park off the more commonly known Aiea Loop Trail down into Kalauao Valley to visit Kalauao Falls and Pu'u Uau. This trail was originally created in 1930 and later modified in 1965 by HTMC. This trail is an intermediate level trail with some steep climbs and descents into the valley. It is best done after a good rain, though not immediately so as it will create some pretty high brown waters. Its best after a couple of days as the water settles into a clear blue hue. The trail is generally well marked with orange ribbons and a few pink bottle caps. There is one short section above the waterfalls (if doing this loop clockwise), where there are several parallel trails that makes it a little confusing. Lookout for the ridge trail after the 14th crossing. Once on the ridge, there are lots of really tall Ti plants. Its not much of a switchback - more like straight up. Watch out for muddy sections with loose footing. The ridge is a beautiful place that connects up to Pu'u Uau. This hill is where the junction from Aiea Ridge and Aiea Loop meets. Return back to the start along Aiea Loop Trail.

Hike was pretty miserable overall. The decent down isn't bad but the "trail" too the waterfall is slippery and possible ankle tweakers. The falls were dry today so that was a bit anti climatic. The next half of the trail is rough, the accent is long and exhausting, great views but not well maintained. Very steep and could be a danger too younger or in experienced hikers.

Would not hike again.

This trail is very hard to follow. We turned left when the loop split. We missed the turn to continue and had to retrace our steps using the offline map I had already downloaded (luckily). Finding the waterfall was easy but after that the trail was not well marked and we got lost several times. Once we finally found the trail (using the map) it was very steep up the ridge and very overgrown. I would rate this hike as hard due to the un marked trail and steep climbs up the ridge. If you're looking for a view this is not the hike for you. The waterfall is just ok. This hike took us 4 hours to complete.

Went with my kids and baby. Had to backtrack because we passed the mango tree. Our short little legs had a hard time climbing down the rocky part of the trail. It rained a little so the trail was slippery. The waterfall is pretty small and not what we expected. We decided to come back the way we came because we didn't want to chance the other half of the trail with everyone's reviews saying that half isn't maintained.

got lost coming back up, we couldn't find the turn to go back uphill. It takes some strength and endurance to get back up once you do find your way back.

The waterfall was on the small side, but not a lot of people are there to crowd it.

I am not even sure why this is rated difficult. I was very disappointed.

Mislabeled as HARD. Nothing hard about it.

I love this trail. People get lost because they don't know where to turn. About 20 min into Aiea Loop, there is a trail to the left. If you get to the big power lines you have gone too far. Follow the side trail down the ridge for about 30 min. Check this app periodically for the next turn - it's on the right by a big mango tree. Then you'll go straight down the cliff to the river. Once at the river turn right going upstream. It seems like a long way but is worth it. Go after a big rain. Lastly, leave the way you came. The rest of the loop is not maintained and is not pleasant at all.
