    Looking south from the top

    Excellent hike! Fairly taxing, good length of 4ish miles round trip (we only did the eastern leg of the three trails, a loop doesn't make logistical sense unfortunately), pretty panoramic views at the top. I would recommend not doing this if it is raining; it was already a bit slimy and slippery in parts despite it being a sunny day. Easily one of the nicest hikes in the area. We met a few people, both locals and non-locals, on the trail and everyone is so pleasant and friendly! Make sure you go all the way to the lookout point at the giant's "chin" if you feel that you have solid footing and are not particularly vertiginous. There are also some hidden little caves near the very top on a tiny side trail. Nice views throughout the entire hike but often you are walking through rainforests, which in and of themselves are pretty but they also obscure the view for most of the hike except the lookout points. Also, there was some sort of small little vagrant camp set up near the bottom of the hike; there was a rottweiler and some other very aggressive looking dog mating in the middle of the trail and they were understandably very mad when we turned the corner and they were there. Fortunately they ran away to their owners at the little camp within ten minutes and we continued on.

    Also known as the Sleeping Giant hike because from far away the mountains look like a giant human sleeping facing up. It's a hotter hike compared to the ones by Koke'e State Park or the northeast side of the island. There's a bunch of trails to get to the top and they start on different sides of the mountain and they fork often. So remember where you came from because we ran into a few people that were lost on the trail. The view during the hike from the south side is mostly of Kapaa but the view at the very top is a 360 view and its worth the effort from the picnic tables. When you're at the very top you're actually standing on the face of the "sleeping giant". It's not strenuous, or difficult, it's easy for the most part. Until you get to the picnic tables... Some people with little kids decided to stop at the picnic tables. It's a cool hike but it's not a favorite.

    Fun hike with beautiful views. Can be a bit tiring for beginning hikers, but definitely doable if you take your time. We did the East Trail Head, which starts from the parking lot off of Haleilio Road. It's about a 4-mile round trip. It took us 3.5 hours, which included ample breaks on the way up, plus time at the picnic area at the top. There are only a couple of tricky parts. The first is when you get to the 2nd "Stay on the Designated Trail Sign". Do not go on the trail behind the sign, which curves around the mountain. Go to your immediate right. It looks like you've taken a wrong turn because you face a short rock ledge, which doesn't seem to go anywhere. But once you climb this ledge, you'll continue on the trail to your right. It feels like you're going the wrong direction because the path starts to head downward again. But keep following the trail, and eventually it will head up again. The second tricky part is when you get near the top at the picnic table. You can stop here or continue up a bit. When you face the picnic table, coming up from the East Trail Head, the view of the ocean will be to your left (9 o'clock), where the bench is. In front of you, a bit to your right, (about 1 o'clock and on the other side of the picnic area), will be a small path that takes you even further up. It's about another 8-10 minute hike to the top. The trail is narrow, but there is a lot of brush on the sides. You'll pass a sign that warns you not to go past the end of the designated trail. Once you pass this sign, you'll end up at a vertical wall again. This is the 2nd tricky part. You'll have to climb this again to make it to the very top. At the top of the wall, head left for a beautiful 360 view from the Sleeping Giant. This last part can be dangerous and is not part of the designated trail, so it is not for everyone. Be careful if you decide to do it. I would say the hard part is not the dirt trail to the top, but the rock wall that you have to scale.

    AKA Sleeping Giant, 1200 feet high, with coastal and inland views. According to a guide book, there are 3 ways to approach. We did the shortest way, mountain side trail (shortest): Take Hwy. 580, kuamoo Rd., mauka from Wailua Bay at the Coco Palms. Nice elevation, nice view, totally satisfied. 1 hour up, 1 hour down. Nice evening little hike. Will do this again. YELP 365 - 239/365

    My husband and I did this fun hike today and really enjoyed it. We followed the gps but if you blink you might miss the parking lot. It seems like people like doing this hike in the late morning or afternoon it we did it at 7am. We had the trail to ourselves until about 1/2 back down. Ok some suggestions: *Bring water regardless of what time you go. *Use a backpack if you're going to be carrying things because you will need to have your hands free (sometimes going up/down you'll need to grab onto the rocks/branches for some stability) *The trail is pretty good overall but because it rains regularly, it does get muddy and slippery. Don't think any type of flip flops or sandals will work. You will regret it. *The picnic area is a great place to relax a little but it's not the top so keep going if you're up for it and get a 360 degree view. *Take you're time going up and down or you'll slip and slide. (We saw several people pretty muddy) we stayed fairly clean and it took us just under 3 hours to do the round trip. *Stay on the trail. We accidentally we up then came back down a trail that probably the locals might use but was very difficult. We doubled back and found the main trail. Enjoy!

    This is the best trail to start early morning and finish right as it gets warm. It is uphill most of the time and not always week marked but everyone was helpful and nice to chat with along the way. A little muddy in the upper areas, but not too bad. I'd say this is intermediate and should be done in cool temps.

    Short (about 1 mi each way) trail that took us almost two hours round trip. We did the West approach. There are two ways to start from the West- the trailhead off of Kamalu Rd, or by parking at the end of Lokelani Rd. As previous Yelpers reviewed, I would rate this as moderate or strenuous, given that the trail is straight up almost the entire way. Would not attempt to do this trail if it recently rained, given concern for mud and falls. Beautiful, mostly shaded, and the views are worth the effort, but would exercise extreme caution if you are considering continuing past the picnic area.

    Sleeping Giant is right behind my house so I hike this trail often. Things to know: there are 3 different ways to access the top of the mountain: from the East (aka Houselots side) there's a parking lot at the far end of Haleilio Street and the trail heads up from the right side of the parking area. From the West, there's 2 ways to access the trail, but only one really goes up towards the top. The other is more of a loop trail around the perimeter of Sleeping Giant. The parking lot for the trail that heads up is at the far end of Lokelani Street. Park and walk thru the gate and up the hill to the left. This trail joins up with the East trail about 1/4 mile from the picnic tables at the top. The access for the 'perimeter' trail is located off of Kuumo'o Rd about 1/2m above Opaeka'a Falls - look for the yellow gate. It loops around and eventually meets up with the other west-side trail, but it's kinda a boring hike compared to the other two. With ALL that info you should be set! The trails are all dog-friendly safe and pretty well marked. PLEASE do not cut the switchback corners as larger and larger sections of the east trail are washing away...it's only a few extra steps to save the trail. You can hike up to the picnic tables a the top and sit on the RESPECT bench ^=^ or if you continue up "the chin" to the very very top you can explore the cool cave that goes through the entire mountain...awesome stuff. This last bit is semi-hairy - not for little kids, older folks, people scared of heights, etc. But for most people it's more exhilarating that sketchy.

    Wonderful for a quick hike. Not overly difficult. A big time trail enthusiast could finish it in an hour and a half; a rugged terrain jogger could probably finish it in less. We chose to take a slightly slower pace pausing here and there. Not for you if you don't want to hear the hum of construction from below. We also got there right at sunrise and were the first people there. The trail was pretty much to ourselves until the way down-- go early! Lovely view that kept getting better! A rain jacket isn't a bad idea if you dislike a little rain.

    I made it to the top.
    David B.

    Atop the Sleeping Giant you'll find the best views possible if east and south Kauai. Strenuous at times, especially when the sun is beating down on you, the two mile eastern trail is manageable by moderate to experienced hikers with little trouble. And the payoff at the top, if you've got the stomach for the final ascent, is well worth the effort. A great Kauai trail.

    This is a difficult hike. Rocks, branches, steep elevation. It is not a leisurely stroll. That being said the views are gorgeous!

    Wow, this trail was something. I came to Kauai for a jungle…read moreadventure, and I definitely got one here! It is such a magical path First of all the trailhead is pretty hard to find and kind of hilarious. There is literally no official signage, except a sign that reminds people to stay quiet since they're in a neighborhood. There is a designated parking lot may be about a quarter mile away, so you're not supposed to park in front of peoples houses. As you're walking from the parking lot towards the trailhead, someone's house is labeled with a cute story between frog and toad that says that the trailhead is three houses down. There's the most narrow little entryway into the trailhead. We also thought it was funny after our hike that almost all the yelp reviews talk about how easy this hike is. We're a pretty fit family, and I'll just say that after a week of rain, this trail was quite treacherous, so part of our experience may be that we got unlucky with the weather. We had to try really hard not to slip at every step. There's areas down to the river in the waterfalls that are really really steep where we had to grab onto trees and branches to not cause a landslide. We were caked in mud from the knees down and on our hands for most of the hike . Definitely need shoes with good grip - our Keens worked well since we were able to rinse out some of the mud in the river. It rained on and off during our hike, but luckily there were so many trees that the rain itself was not too bothersome, but most of the trail was soaked in mud puddles . We only made it to the first waterfall because of the conditions but still had a blast ! We had a lot of fun but I wouldn't have brought my older parents for example so be wary depending on the rain !

    A relatively short and easy hike. The whole thing took just over an hour for us, which includes the…read moretime we took to stop for photos and admire the views. We did read that it can get very slippery and muddy at times, but luckily we didn't run into that issue. The ground was pretty dry when we went, and I had no issues with my super old shoes that had no traction left. There are also few areas when going down to the falls where you need to navigate down some steep/rocky areas, and then back up when coming back. Shouldn't be an issue for those who are able-bodied, but just something to keep in mind if you were hoping to come with those who aren't (maybe not the best idea). The falls were a bit small when we went, but overall the hike was pretty with lots of lush greenery. We saw some people jumping into the water, but we were way too lazy for that. We also read that septic tanks from the neighborhood may leak into the water. Since the trail starts in a residential neighborhood, please be respectful and mindful when walking past homes to the trailhead, and don't be too noisy or trespass. We also parked our cars nearby at Kapahi Park. The neighborhood roads are small and I can see why residents would get annoyed with people constantly cluttering up the street to go hiking. Overall, a great option if you're looking for an easy but beautiful hike. Maybe consider hiking shoes if it has recently rained heavily since apparently it can get muddy.

I do wish they would cut down some of the weeds as it was a bit tall. Luckily, a fellow tourist that took our family photo was tall and so he was able to capture a photo of us and the fall. I do recommend visiting but just know that the parking is chaotic. Oh, and it is free.

    I'd like to be transparent, I'm a little bit confused about a few things…read more.. I had reservations made ahead of time to hike the famed Kalalau Trail 2 miles to Hanakapi'ai Beach and another 2 miles to Hanakapi'ai Falls. Upon driving to the Kalalau Trailhead, I entered Ha'ena State Park. I thought to myself, "oh, wow, cool, I didn't even know Kalalau Trail was within a state park!". Now, lol, after parking my car and reviewing the Kalalau Trail hiking guidelines, it was time to venture over to Hanakapi'ai Beach. Not even 1 minute into the trail, there was a clear sign stating I was now entering Na'Pali Coast State Wilderness Park. What??? But I thought Kalalau Trail was part of Ha'ena SP?! So both? What's the difference between Ha'ena SP and Na'Pali Coast SP? I guess the only thing to do is venture over to Google and search for the answer... The only reasonable solution I discovered on Google is Ha'ena SP hosts the parking lot for Kalalau Trailhead. But, once you start hiking on Kalalau Trail land, you're officially now entering and located within Na'Pali Coast boundaries. And with this info...I believe there are more options for activities within Ha'ena State Park, although I never got around to do any exploring. Now, if you're specifically visiting here for the Kalalau Trail, I'm convinced it's Na'Pali Coast territory, lol. Finally, trying to get to the bottom of this strange mystery, is when visiting Kokee State Park on the opposite side of the island of Kauai, most of the overlooks and lookout points there showcased the Na'Pali Coast. But I guess for Kokee SP, you're not actually inside Na'Pali Coast State Park land, you're just admiring the views and sceneries of the Na'Pali Coast from high above. Lol, yes...maybe I should have been better prepared ahead of time. With all this said...let me quickly return to the Kalalau Trail and provide a few highlights about the experience and what you can expect inside Na'Pali Coast State Wilderness Park... - While hiking to Hanakapi'ai Beach, a lot of the beautiful Na'Pali Coast setting will be revealed. There were moments to take a break from the trek to appreciate the landscape. - When the clouds went away and the sun shined, the coastline illuminated the Pacific Ocean waters. - You'll also capture a vantage point of Kauai's lush green island vegetation and rain forest appearance. In total, that's what I believe made Na'Pali Coast State Wilderness Park rewarding. It's hiking among nature until Kauai's colorful coast comes into appearance. The surroundings exude that vintage, tropical, Hawaiian image that tourists anticipate when visiting. At the time of visiting Kauai, I found it difficult to understand whether I was hiking Kalalau Trail within Ha'ena SP or Na'Pali SP. After completing some detailed internet research, I'm confident the popular hike is connected with Na'Pali. And with that understanding, Na'Pali Coast is a winning state park.

The view is not too much but the green lush vegetation will still make you feel refreshed & relaxed at some point. It is a friendly-hike to do so kids or old folks can definitely enjoy this. Please don't forget to bring your water and do wear proper hiking clothes. I advise to wear good hiking shoes & bring quarter zip as temperature can drop any moment. Do not forget that Kauai got more rain in most places in the US so I suggest you bring your rain jacket in case you need it. And most of all practice LEAVE-NO-TRACE POLICY all the time. Mahalo for reading & happy juandering fellow Yeeps.
