have you ever done a hike and been like, "I just want this to end?"... that was this hike for me. I'm good with a fair amount of mud, but the first half of the trail, going counter clockwise, was MUDDY, the squishy kind you can't find your way around. Where's there's mud there's water and where there's water there's mosquitoes! I kept spraying myself and clothes with extra strength deet, and could feel my cells mutating work each application. Oh, watch out for red fire ants on a tree you have to get around. It's not all bad. The second half was actually nice, and the up to my knees stream crossings cleaned the mud off my shoes, squish, squish on I go. On way out, I was greeted by about 15 dogs, a few stoned owners who were going to hunt. "Pitbulls and Pot heads" new series? I'm sure they must have caught something bc ALL 15 of the dogs pooped on the trail and could now gallop lightly after thier prey.

It was great! My two sons ages 6 and 8 were able to do it. We are a moderately active family. It was muddy but not overly.

this was a great trail. plan to get wet. the alltrails map for this loop includes the "alternative route" which has the paved portion for the reservoir road. to do the park map route, follow my recording, just note alltrails will keep telling you you are "off route." To follow my route, when you arrive at the trail head information sign you'll want to keep left but don't go down the maintained portion to the far left, instead there is an earth trail with a sign that says "trail not maintained beyond this point," you'll want to go that way. it includes more elevation changes right through the heart of the valley where you are surrounded by the jungle. there will be a lot more mud, an extra river crossing, more downed trees to climb over or or shimmy under, but we were happy we took that path rather than the paved portion. didn't see any boar, but definitely heard them rustling and snorting. go early, we only ran into a couple of hunters about halfway through when starting the trail at about 7:45am, otherwise we had it all to ourselves. I recommend counter-clockwise so you can hit the dammed up portion of the river with a rope swing near the end of the hike for a nice treat to clean off and cool down. will definitely do this again and go to the pools indicated on the park map.

HikingBugsMuddyWashed out

This was a great hike for kids and dogs. Fun water crossings and bunkers. It is wet over on this side today but there was no deep mud because of the fallen leaves that fall on the trail. There are two spots where the wash out is causing some possible future problems but nothing that would cause a dangerous situation. We did the trail clockwise and found it to be fun because we ended on the paved section which allowed our shoes to “unmud” haha We will be back to add the second loop and find the pools.

The trail is maintained. Give yourself at least 4 hours if you like to enjoy the journey.

Definitely more of a nature trail than a technical/challenging hike, but really enjoyed this little adventure with our dog today. We did the loop in a clockwise format. Trail 2 to 1 was the muddiest of the entire hike, but we didn't mind it because we could wash off in the dam or at the beach afterwards. Probably in total from walking to our car, doing the loop trail, & checking out some of the off-shoots like the bunkers & back to the car was a total of about 5 miles. Did it all in about 3 hours & we took our time exploring & enjoying the stream. Going to do this one again & check out the trail to the pools indicated on the map. You can grab a paper map in the parking area, by the way. Keep in mind no cellphone service. This is a great hike for dogs (as long as they're not skittish of water/stream crossings) except for the fact you've gotta be aware of the risk of hunting dogs & wild pigs on the trail. 4 medium sized pigs crossed about 25 feet in front of us between Trails #2 & #1. We just let them pass & didn't have any issues. Trail is easy to follow. Wear bug spray & be careful not to touch the palmetto-like plants, as they have razor sharp fronds. No amazing ocean vistas/scenic points, but you do get some beautiful fog-capped mountain views in some parts & being engulfed in the peaceful forest in itself is amazing. Grabbed fish tacos afterwards up the road at North Shore Tacos & they're hard to beat

No views more of a walk rather than hike very disappointed. Give 2 stars instead of 1 due to two water crossings about knee high

Pretty easy to navigate. There are some places where you have to go over some branches in the trail and cross the river twice but there is very little elevation gain on this one. Lots of sign of wild boar. If your interested in history this area was used in WWII for jungle survival/warfare training & there are still several bunkers in the jungle. Seeing these was the highlight of this hike for sure!

Quiet walk through jungle. Can be muddy when wet as well as dangerous for stream crossings. Mostly Hala, Inkberry, and Guava for vegetation. Stream crossings have deep pools and moving water, but no true waterfalls.

The trail features WWII bunkers in the middle of the jungle. The old coral road is still on many parts of the trail. Very interesting for history buffs! Otherwise, a lot of mud and hala, and a few deep river crossings, but otherwise one of my favorite hikes!

I would skip the hike and go to #4 where the payoff is; cool swimming hole with a rope swing. The hike is only a jungle experience no vistas and very little open patches of sky. Think dark, very muddy, overgrown in spots, thick thatches of jungle tree’s, no birds. It’s only a 1 star for the swimming pond at the end! It was also hunting season for pigs so we had to deal with a large group of local kids and their 6 dogs who had a little fun at our expense.... as we left they told their dogs to go get us then when we yelled at the dogs they called them back and laughed! It was a little sketchy.

Wet. Mud. Fun! As long as you expect it, a great trail for an adventurous hike. Surprisingly, one of the better marked trails. Two river crossings and trails that at times are streams. Supposed to be the wettest valley on Oahu and I believe it.
