The 2.5 mile hike down Waimea Canyon to arrive at this site is worth it for the views alone. The campground is rustic. There is one outhouse and a covered picnic area. Our site was directly on the river. We stayed in the river or on the rocks in the river to swim, cook and hang out as it was the only spot free from mosquitoes. The views from the bottom of the canyon were breathtaking. We were the only campers when we went to bed but woke up to 2 men with horses and hunting dogs staying there.
The arduous hike in and impending brutal hike out make this campground a haven for those willing the make the trek. There’s a compositing toilet and a shelter with a picnic table in case it rains. Lots of trash from irresponsible hunters/campers near the shelter but the camping pads close to the river are beautiful. TONS of bugs that you can’t really feel biting you so bring really good (and environmentally friendly) bug spray. We took baths with bio soap in the river which flows strongly enough for fresh water (steripen that!) to drink but has small pools to sit in to cool off from the hike and wash up for camping. Lots of roosters and quail, hunters seeks wild pigs down I. The canyon. ATVs come through on occasion but this is a very private campground. Good tree coverage as it rains nearly every day in the canyon. Hikes around the area lead to various waterfalls and natural water slides. Don’t leave valuables in your car (we left our car unlocked to avoid broken windows - 8 piles of shattered window glass on the side of the road when we arrived at the trailhead (pull off on the side of the road to park and go there, no true parking lot).
Wiliwili is a site at the end of the kukui trail - down to the bottom of Waimea canyon. This place is well received by hikers as a beautiful place to cool off in the stream. This is also the first site you hit if you dare to venture further into the canyon off this trail. There is a fire pit and plenty of tinder which comes in handy since the second thing you will notice after the stream is the swarms of mosquitoes awaiting your arrival. Bring bug repellent and don’t play it safe with natural remedies, get the stuff you know works. We enjoyed hanging up hammocks here and laying in the streams gazing up at the canyon and stars. Lovely place but I surely regretted the 2.5mile ascent back up the canyon walls with 20lbs on my back. Travel light and you will enjoy this place. visited in June and it was great - no rain.
