    After you climb to the top of the "end of the road" through the valley, you reach this sign.
    John H.

    Tripler Ridge is a hike along a ridge that starts at Tripler Army Medical Center and ends at the summit of the Koolau mountains. People have hiked this trail starting at the back of the hospital but the easier, non-access-needed way to do it is to start at Moanalua Valley Neighborhood Park at the end of Ala Aolani Street. I suggest you not park in the parking lot as a neighbor who lives nearby has called the police to report people parking in the lot and leaving the City and County park to hike into the valley. It's a long, relatively flat hike from the park. There are several ways to access the summit. The only one I've taken entails hiking past the detour to the Kulana'ahane trail and continuing straight along the trail till you start climbing up the right side of Tripler Ridge. It's about an hour hike from here to the summit. If the weather is clear, you will be rewarded with breathtaking views of the Windward side and, looking back, to Moanalua Valley and the south shore of Oahu. Many people use parts of this valley hike to access the top of the Stairway to Heaven. It is possible to hike from the summit of Tripler Ridge along the Koolau Summit Trail in either direction but be very careful as the summit trail is narrow, crumbly and drops several hundreds feet, sometimes on both sides.

    We chose Tripler Ridge to go to the Stairway to heaven. It was very nice change because he was usually we take the regular way + Moanalua Ridge. Tripler Ridge has more plans and trees around in comparison to the regular way. It was a little bit muddy. I recommend spikes if you have some. Have a great time and lots of fun.

    Trail leading to electrical towers is a fully paved uphill trek

    Review for Tripler Ridge Trail up to the electrical towers: The trail up to the electrical towers is a fully paved steep hill which makes it family friendly and baby wearing friendly. Technically one can push a stroller up the trail, but I would imagine it being quite challenging to push it downhill. We went on a hazy day, but I'd imagine the views on a clear day would be GORGEOUS!!! But then that would be scorching hot sun on your back as this trail is completely exposed to the elements without an ounce of shade. I'm not a fan of paved hikes, but since this trail has amazing views and many many more miles beyond the electrical towers I rated it as 2 stars. Hoping to explore past the towers soon!

    I wasn't going to write a review because I didn't technically complete this hike. Then I thought about how my review might help other mommas or novice hikers... so here goes! This review is only for the paved part up to the tower/electrical lines. This portion totals about 2.6 miles roundtrip. I first hiked this trail with a group of other momma's and children. Park in the parallel parking spots on the side across from the homes. We followed the white sign that said something along the lines of "access for hikers." When you go past the sign, you make a left and step over a chain. The trail itself is easy to follow from here. It's paved all the way to the top (where you can then sneak off to the unpaved, ridge part). There is some incline at the beginning, but nothing that the average person can't handle. The views around you are beautiful. Be sure to stop and look behind you every now and again! Also, this is is a pretty well shaded hike. While this is a paved hike, I wouldn't recommend a stroller. I'm sure you could do it, but it seems like it would be a pain. The only reason I won't give this hike five stars is because I wasn't impressed with the views at the first "end point" by the tower. You couldn't see much of anything. Nonetheless, it's still a nice place to have a picnic or a quick snack before heading back down. Heading down is when you'll really get to take in some of the great views. I'm planning to do this trail again soon. Even though it's not the trail with the BEST views of the island... it's empty, well-maintained and offers a nice, safe option for cardio!

    The end of the easy part...

    Note: Review for the trail up to the top view point next to the tower/electrical lines only. Beautiful walk that gets a bit steep so if you're talking and walking you may get a bit winded. On the way up, there are lots of small wild guava and bird life. The views get pretty good fairly quickly with ability to see Diamond Head and the Salt Lake/Pearl Harbor area. To access the trail head, you'll need to know someone who works or lives at Tripler and guests will likely need to show ID, so be prepared at the front gate. Parking is residential and signs mark the start. Don't forget to turn left into the trail's metal gate once a bit up hill on the asphalt. Good walking shoes are needed, as it might be tough to do in slippers. You will likely run into people walking their pets and also maybe a wild pig or two as we were told. There's also a chance of mosquitoes so bring some repellent. Like I said, we stopped at the top where the power lines are about 1.5 miles in, post this, the hike gets tough, sometimes muddy and is long--supposedly going all the way to Haiku Stairs (this is the 8-hour trek some other Yelpers are referring to). Given the chance I'd go back but be sure to put some good shoes on and bring repellent for my ankles! Other than that a camera phone and sunscreen are it to enjoy the gorgeous viewpoints! :)

    Marker 12 along Moanalua valley. Tripler trail is a few feet after it.

    This is one rigorous and dangerous Hike. Definitely "not" for beginners nor faint of heart. We began our hike at the beginning of Moanalua Valley Neighborhood Park at 0730am. Slip through the green gate which stops vehicle from going into the path. (Ignore the sign/ trail to the right of that gate). As you go through the Path you'll keep seeing a split, Just keep right. Also you will see a lot of pink and yellow or even blue ribbons along this path that leads to trails, Ignore them! I strayed away from my plan and took one of the yellow and pink ribbon trails just to end up in front of a stone wall that my group would never be able to climb. Lost 30mins up and down that trail. Keep going through Moanalua valley path and keep an eye for a wooden post on the RIGHT side that has a yellow number 12 on the top also refered to as marker 12. This is the beginning of your ascension towards tripler ridge. Once you go into marker 12's trail, it is a straight shot to tripler ridge summit. Tripler ridge summit will be a clearing with nice 360 degree view with Kaneohe right up front. At the very last leg of Tripler ridge is a good amount of ropes that's goes up pretty steep but I wouldn't consider this as rapelling up. Although this is where half of our group broke off and turned back. Those of us that kept going made a left from the Tripler summit and you'll be Trailing Ko'olau Which has a very narrow trail with nothing but a drop on both sides. We we're walking low because of the winds and of cours because of the cliffs on both sides Further down is a signal tower with winds kickin at you enough to give a 160 pound guy a good push off the cliff. Our plan was to keep going through this Ko'oloau trail and eventually get to Radio Station on top of Haiku stairs; but once we got to the signal tower, Me and the rest of the group made a decision that the winds further down is just too much, We do not see any ropes further down so we decided to turn around back to tripler ridge pretty much the same way we came in. We started heading back at 1 pm and gladly got back down by 4:30pm. At the end still feeling accomplished we got to the Tripler ridge summit and more than halfway through Ko'olau Trail. A bit dissapointed we didn't reach our goal to the top of Haiku stairs but it is what it is and this is a ver dangerous hike from the beginning. Still an awesome experience for anyone daring to go. Maybe next time. TIPS: I'd definitely plan this weather wise, we caught a bit of rain but it wasn't too bad. Not sure if the gusts up in Ko'olau ever settles down a bit but the weather was pretty clear with some fog when we we're up there. Gloves helped a LOT for those ropes and the inclines to save your legs from some work. I brought over 3Liters of water (3 tall bottles of water, I realized it should get lighter as I go anyways and alas, it came in handy when we realized we'll have to head back down same way we came in. Bring light snacks to keep you going. You will want a light jacket or windbreaker when you get to Ko'olau ridge. It would've pretty cold if not. Good hiking shoes is a must. I have a gopro Hero3 with me and my mistake was I kept using that bluetooth and wifi. Battery only lasted halfway.

    So probably one of my favorite hikes so far. It is a long hike to the summit and right now the access through the army base is closed so if you turn right before the guard post and follow that road into the neighborhood an access road with a small metal gate will appear on the left. Park away from houses and make your way up the trail to a large concrete water tower and walk around to the right and eventually you should see some orange trail tape showing where to enter. A little ways in there will be a folding chair in a tree...yeah don't ask I have no idea. Just keep following that until to reach a fenced in area and follow it down to the left and around until you reach a paved road. Walk up that and just keep going straight. Also I was wearing shorts on this hike...big mistake the first portion is very overgrown with ferns so our shins were insanely scratched up by the end of it. Overall it is well maintained and once you reach the summit and go towards middle ridge someone has been putting in brand new ropes so a big thank you to that person. Make your way down middle ridge until you hit the road and we went right and eventually we arrived at the moanalua valley trail head where we staged our other car. Along the way there's some cool ruins and stuff to see if you aren't too tired. It took us around 8 hours but we spent a lot of time at the top taking in the views. Lots of water at least 3L per person.

    The views form here are worth the hike. Try to start early to watch the sunrise and you will have a lasting memory of a lifetime.

I travelled up Mount Tantalus to the Park yesterday with my daughter. We travelled through beautiful dense forest at the Park entrance. At the highest overlook, we could see everything and more from Diamond Head out to (and beyond) the airport. We could see all of Honolulu. I felt like we were on top of the world! Plaques offer fascinating overviews of the history and geology of the landmarks below. We could even see inside the famous tuff cone, Punch Bowl! Nearby is the first macadamia nut orchard in Hawaii. The overviews are paved with railings and easily accessible. The Park offers picnic areas with a couple pavilions and picnic tables. There is a charge for non-resident parking of $7 that can be paid electronically. Resident parking is free. Parking is limited, but there are several parking areas. We had no trouble finding parking mid week. Warning signs tell guest not to leave valuables in the car. Pu'u Ualaka'a State Park is only two miles from downtown Honolulu (maybe a couple more miles to the top). The Park is an easy 5 star and worth a visit.

One thing to note is that it does get really windy here. There are two parking lots available near this lookout. The one right next to the lookout is very small. It only holds about a dozen cars.

We started out around 8:45 AM and by the time we reached the waterfall, it was getting full of families and pairs of hikers. I recommend go early to skip the crowds. The hike itself isn't too technical and there are only a few places where you have to step up high over a rock or scramble through a stream.

    Here are clear and concise directions for this hike!!…read more Main parking off Pali hwy. Entrance is easily visible. You'll enter the bamboo forest. Within the first 50 feet it will split into a Y trail, take the left path. If you go straight you'll likely end up in the bamboo section for 20-40 mins. If you do not exit the bamboo area within 10 mins, you're lost. You'll exit the bamboo area through a lifted/broken section of the fence. Walk uphill onto the paved pathway. This will open onto a wide valley. You'll pass a large bridge structure. Follow that till road till you get to the supply shed structures. Look for a small concrete stairway in the trees. Stay left mostly, and look for pink ribbons. Pass the old fenced off pool looking area. Once you hit the rock/mud path (approx 10 mins) there's a hard right turn down into the main river area. A large tree has fallen so you'll need to spot the ribbons, and climb over this tree. If you pass this fallen tree by mistake, the trail will seem oddly difficult and dense. You'll need to turn around. Walk until you see the man made rock wall with a small waterfall, and walk across this to the other side. Follow the ribbons up the path and you'll need to cross the river 3-5 more times after this. Keep looking for clear open paths. There's two ways you can continue after that point so don't worry. (One way is just more difficult) Before the waterfall there's a larger section of rocks you'll have to climb over. Main takeaways: You will have to walk across slippery rocks several times. It is muddy. It's not that difficult but can be dangerous at some parts. If you don't see a pink/orange ribbon for more than 5-10 mins at any time, you are likely lost.

We did it all through Groupon to get picked up from our hotel and dropped off as well. The trail is definitely a popular hot spot for tourists but we didn't mind the crowd. We did an early one to see the Sun rise, though by the time we got there the sun was out already. Totally okay. Water was provided by our tour guide. He gave us some history on Diamond Head and then dropped us off and gave us 2 hours to explore before getting picked up. Thank you Jonah from Fun Hawaii Group! Aaaand we were on our way! Paths were clean and clear of overgrown plants for the most part. My wife and l hike regularly so we didn't feel the hike was bad at all. Weather was perfect (it rained on us a bjt too which was unexpected but fun) and it wasn't a long hike either. There are steps involved which we enjoyed for the added cardio! When we made it to the top it was breathtaking! The views of the ocean and the mountains were beautiful! Still find myself looking at photos. It was truly magical. We were in paradise!

    Hiking Diamond Head State Monument is honestly one of my favorite things to do when I visit Oʻahu…read more It's about a 1.6 mile round trip hike and took us around 1.5-2 hours, but this can vary depending on stops and crowds. I'd say it's a moderate hike--not super long, but you definitely feel it. There's a pretty significant incline, especially toward the end with all the stairs, so it gets your heart rate up for sure. The path isn't paved, so it's a mix of rocky, uneven ground and dirt trails, and it can get a bit muddy if it's rained recently. There are also these dark tunnels you walk through, which was actually really cool and made it feel a little more adventurous (just use your phone flashlight). The best part is definitely the view at the top. You get these insane panoramic views of Waikīkī and the ocean--totally worth the climb. A couple quick tips: make reservations before you go, get there early because it gets hot fast, bring water, and wear decent shoes (especially if it's been rainy). Also expect a little waiting in tight spots like the stairs near the top. Overall, it's a fun hike and 100% worth it if you're visiting.

I love the combination of this trails because the variety of beautiful views, landscapes, type of surfaces. Dense lush rainforest to dryer areas with a variety of foliage. Started at the Makiki Arboretum trail, taking the loop to the right on the Maunalaha Trail. This section will get the blood flowing as you climb upward over a very rooted trail. Once you arrive at an area with metal benches there is an intersection of multiple trails. Take Makiki Valley Trail to the Right. After a short hike take the Moleka Trail to the Left. The Moleka trail becomes the Manoa Cliff trail which you stay on for a number of miles. If you struggle with narrow trails with drop offs this section may not be for you. There are beautiful views of Manoa Valley from the trail. Some sections of this trail can be muddy. In the past Hike once you go through the gate the Manoa Cliff trail takes a sharp turn to Left at Intersection of other trails. In our case there was a recent landslide and there was a warning sign not continue on the Manoa Cliff Trail. No problem we took Pauoa Flats Trail until we reached Kalawahine Trail and took a Left on it. Take this trail until you reach a paved road, take a right down the road until you see the next trailhead, Nahuina Trail which zig zags its way down. When you come to Makiki Valley trail go left. When you reach Kanealole take it to your right. This trail will take you back to trail you started on. Since there are so many different trails to do this loop I suggest using Alltrails download. We clocked over 10 miles. I'd rate it as intermediate. Bring plenty of water, I carry crampons in case there are muddy slippery areas. Would not do if heavy rain or strong winds expected.
