Jan 2017. Did part of this trail a couple days ago, came back today to do the full loop and loved it! Muddy in parts, but less so than Hau'ula loop last week. Parts of the trail are damp and jungly, other parts more open and drier. I didn't have my phone or a map, but the trail was very easy to follow, and marked the whole way with pink and orange ribbons. I went counterclockwise (i.e., took a right when I came to the hiker sign), which meant the ridge with ocean views was at the end. The ridge portion is a relatively short stretch of the trail overall though. In the counterclockwise direction, the trail goes up for a while, then down for a while, then another short up and down at the end. Wearing short sleeves, long pants, and no bug spray, I got two to three mosquito bites (the damp jungle sections are buggy, though sounds like less so than in summer).
Muddy in parts, but I did it in tennis shoes (though they ended up covered in mud). I'm usually a mosquito magnet but didn't have any spray and only got one bite. I went clockwise, beautiful views on the way down. Parts of the trail are covered with soft, springy pine needles that were great to hike on. I saw footsteps but didn't see anyone on the trail. Great birdsong and trees! Don't do this for the waterfalls (they're pretty small) but otherwise a very pretty hike.
Amanda M. on Hauula Loop Trail
it was my first hike. it was fun and beautiful. a little muddy. beautiful mountain views.
Good starter hike. Lots of bugs, but Off! kept those away. Left at about 8am. Easy trail to follow. Maybe a mile of hard-is terrain. Plenty of mud, but easily passable. Good views but not spectacular. Was right by where we stayed though so the accessibility was nice. At the end of the day if you're out in nature, it's a win, but this one's definitely just a primer.
This Trail is the hardest of the 3 Hauula Trails in my opinion, but frankly offers the best view at less than a quarter of a mile in. The rest of the time you're spending it back in the valley, it does clear out slightly near the "end" of the loop to give you another view of Hauula, but nothing as good as the first view port. If you're just looking for a view it's about the best you're going to get early on.
A LOT of mosquitoes, come prepared as they will feast on you unless you brought your DEET.
When I was there in June 2016 near the very back of the trail fallen trees and a small stream made a difficult crossing to get to the second half of the trail.
After crossing this stream and fallen trees I noticed that this portion (the back portion) of the trail had been lightly trafficked if at all in recent months, lots of over growth, so its recommended that you're either wearing long socks or something to protect your legs.
Near the end of the back portion of the trail you'll find it completely washed out, forcing you to shimmy down into a gully of sorts, and then shimmy back up, definitely not something I'd attempt with a kid on my back nor with small children, nor after a big rainstorm.
Even with all of these issues I felt this was the superior trail, take a look at my photos, the view is worth the hike alone!
Completed both loops on the Hau'ula loop trail. Not much for scenic views on the top of the hill compared to other trails in Oahu, but none the less still beautiful scenery all around the jungle. Had to ford a little stream on the second loop trail, but not too dangerous at the time. The slight climbs were a decent workout. Slippery at times.
