    East Trail to Forehead
    I made one attempt to get up this trail and it started to rain - I aborted and went back on a sunny day. I HIGHLY recommend that you do NOT do this one in the rain or when it has recently rained. Part of the trail is the water runoff channels on the hill. It is a rustic trail but not at all very difficult, I would rate it a good "medium" difficulty. It is 1.6 miles to the top according to my GPS and climbs 1200 feet. I am 75 and made the return trip with several viewing stops along the way in 2.5 hours. It could be done faster but I suggest you take some time to enjoy the nature along the way. The most challenging spot is about a third of the way up where you are faced with a 20 foot vertical cliff. It has small foot holds so quite doable but at first glance appears like it could not be the trail. Vistas are in many spots along the way and it gives great views of the entire coast line and from the top also in the inland direction. If you need a rest when you reach the top (forehead of the giant) there is some tables and a shelter available. There is NO sanitary facilities so be prepared and remember that what you take in you must take out. People are observing this as I saw no garbage along the way. Great walk - Great views - Great walk.

    Good starter hike
    If you are into hiking and want to brush up skills this hike is great. Well marked trail I consider moderate with a couple of challenging spots and a rewarding view. We went early AM with minimal hiker traffic. I am a runner and 59 years old.

    Oh, by the way, Mer. I think there's something on your head.
    My wife and I decided to check out Kauai since we usually just go to Oahu. As this is the ‘garden island’ we decided to check out the Sleeping Giant trail. As trails go, it didn’t take too long and the views were spectacular. It wasn’t too crowded and many of the people we met at the near top shelter had hiked it before. It was a bit vertical but it only took about an hour each way. Also, on the way there we heard on the radio how fungus being transferred on your shoes could kill some of the tree population. They have a brush and bottle of alcohol at the trail head for before and after but it was empty. Please BYO. The best part was my wife does not like camping or anything related to it. She is not a hiker and had to pick up some cheap shoes at the local Walmart for traction and for something that can get muddy. Picture Meredith in Parent Trap. Her comments on every step were entertaining. She was a fun sport about ‘enjoying’ nature. All I needed was a gecko. 🤣 Yes, I’d do it again, though it would have to be by myself 😏.

    Sleeping Giant will wake you up
    Short hike that will get your heart pumping! Climb 1247 ft elevation in 1.8 miles. Only a few areas that were difficult to maneuver and was more like rock climbing. Great little picnic shelter almost to the top. Could be tough if it had recently rained and made slippery. 65 years old and I did it with hiking poles which made the downhill easier on the knees so o would recommend using them if you are of a more mature age lol.

    would not recommend
    we stayed in poipu and this was an easy drive to the trailhead. we went a few days after rain, but were in no way prepared for the condition of this "hike". reading this trail being described as muddy is laughable, and completely inaccurate. most of the trail looks like a water pipe, with two banks of mud on either side and muddy water in the middle for you to slosh through. it's not a hard hike by any means, but it's not a hike really at all. the views were good, but definitely not worth it. i even told a few people when we got back to the lot that it wasn't worth it.

    Great hike, mid-range challenging, if you are a hiker you’ve got it!
    Solid three mile round trip hike. If you are a regular hiker and are familiar with hills and a little bit of mud (there is not too much mud) you will do fine. We hike regularly in Western NY and the ADK Mountains and this was more like a Finger Lakes Trail than an ADK mountain. It is about three miles round trip and you gain about 1,000 feet of elevation on the hike up; there are lots of switchbacks though so you don’t fell the elevation gain as much. Lots of pretty views on the way up and at the top. Took us about 2.5 hours at a leisurely pace. Nice hike to stop at if going between the north and south ends of the island. And of course once you do the hike you can’t miss the Sleeping Giant every time you pass it on the highway, in fact you keep seeing it clearer and clearer!

    Don't Wake the Giant
    There are spectacular views from this trail, but there is a cost. The trail is not very well maintained with deep ruts, steep terrain and numerous roots to catch your boots. This trail would be very difficult after a rain, when it's muddy. We were caught unawares of a near vertical rock face, about 15 feet high, that required some scrambling to surmount. This was quite challenging for some, especially for those 70+ years of age. I would do this again, but would be better prepared with hiking poles. We did not get to the top due to steep terrain.

    Highly recommend!! Beautiful mountain top views!
    Moderate level hike with gorgeous views!! We finished in just under 2 hours, including taking pictures at the top and a few very short water breaks. A couple areas are more like rock climbing and could be difficult for someone that doesn’t get around well or has a fear of heights. We are 41-51 age range and “fittish” and didn’t have any issues. I would not recommend taking small children to the very top.

    Moderate hike, Great Views
    The two mile East trail is easy to follow and has parts that are muddy and it hadn't rained in a few days. After a rain it would be fairly muddy and slick. We are in our sixties and had to no issues. At the top you get an excellent view of entire area.

    Go Early, amazing views
    Loved this hike! There are some spots that are pretty muddy, so go early before they get really bad (and so you find a place to park!). It took my husband and I about 2 hours (mid-30’s) and found it to be an easy walk/hike. Views from the Giant’s Forehead were amazing and really did feel like we were on top of the world!

Parking is a little tight and the navigator does know where the trail head is. The hike to the picnic table is 1.7 miles uphill with a couple rocky scrambles. If you walk another ten minutes you can hike to the top and stand on the precipice. We didn't because of the heat and our water bottles were empty.

This was a fun, moderate trail with a little bit of scrambling in just a couple places. The place we were staying was closer to the East Trail, so that’s the route we took. There is a small parking lot.

Signs mark the beginning of the trail and there are markers for every 1/4 of a mile. Honestly the beginning of the hike is steep and a little more rocky, but as you get closer to the top the path is smoother.

Like others have said, when you get to the place where the picnic tables are, keep going! The best views are past this point- you’ll see the path that leads to the ridge to the left as you get up to the picnic covering. Once along the ridge, I’d stay to the right. There is a little bit of scrambling you may have to do, but the views are worth it!

I can see how this trail could be muddy after a rain, but when we went it was dry. Wear sturdy shoes for hiking and take water. It took us 2 hours and 40 min, but we stopped and took lots of pictures. We also went all the way to the ridge. If we just did up to the picnic tables and back it would have been 2 hours.

This was one of my favorite experiences on our 12-day honeymoon in Kauai. We hiked the 2-mile trail up and down. Be prepared for lots of mud, bring snacks, and know that there is very steep climbing involved. My poor wife slipped on the mud twice and got a couple bruises, so take it slow!
