Diamond Head State Monument

Sunrise from Diamond Head is magical. Get there at 5:50; gate opens at 6. It'll be dark out, but it's a simple hike . Do it on the first day, when you can use your jet lag hours to wake up early.

A great hike ! Go to the top, bring plenty of water, wear close-toed shoes . Absolutely worth the trek for breathtaking views of Oahu. WWII sites an added bonus. Bring the camera !

Take your time up this hike , but as you get to the tunnel it gets crowded as people are going up and others coming down. Watch your step going up the steep steps.

When you get closer to the top, the path splits to the left and right. Go right and you are greeted with "judgment steps". Extremely steep and challenging, but shorter in distance. Test yourself!

The views are well worth the hike . Bring water , you'll be glad you did. Take your time and pace your hike . It's not a race, but an accomplishment.

Great views and a must if you haven't been up before. I reached the summit in under 30 mins without stopping. Go early because it gets very crowded and is quite annoying to hike with many people.

Not a long hike , but does offer some great views of the Honolulu-Waikiki areas. Plenty of spots to take a break if needed. Bring water . Can be fairly busy, so parking could be tricky.

Lovely walk, take water as there are no water stations on the way up which some guide books state , some clowns wear flip flops on the walk, and read the safety signage

This not-to-miss landmark is one of the most popular hiking trails on Oahu. It's an easy hike for all ages and offers spectacular views . Go early to beat the heat and crowds.

Uphill walking, an uneven rocky path and plenty of steps to navigate. But the views are spectacular. I suggest going with a tour operator and going on the early tour .

Been there, done that, got the t-shirt. OK, no shirt but they sell them. Nice view at the top, easy hike , super crowded . Park at the community college if the lot's full on the weekend, easy hike up.

Fantastic views and fun hike . Recommend getting there early (opens at 6am) to get parking and avoid major crowds. Toward the end are some serious stairs and a 200+ foot tunnel to think about.

Bring plenty of water, you're going to need it! Also watch out for the Japanese tourists in heels, they may take a tumble. But be sure to go all the way to the top. The view is incredible. STAIRS!!

You should definitely bring a bottle of water and wear tennis shoes ! The terrain is rocky, steps are steep, and some entrances are very low (you must crawl to get to the very top). But well worth it!

A must do in Ohau. A medium level hike . Meaning younger kids (above 5yo) can do it but no one with mobility problems. A local told me they need to send paramedic 2 or3 tomes a week. View is AMAZING.

There's a fork in the road -- well , path -- that leads either to hundreds of steps or a few easier ramps. Take the steps: It's challenging but way more rewarding. You'll have stories to tell!

Awesome views . Hike to the top is half an hour and fairly easy. Make sure you take the stairs all the way to the top

Go for a run here - you can be on the top from Waikiki in 30 minutes! Don't forget to take $1 for admission though.

The hike is well worth the trip. Maybe a half an hour or so up but the view from the top is well worth it!

Hike Diamond Head on a Saturday so you can start or finish with the farmer's market held at Kapiolani Community College. Go early to avoid the heat and crowds.

Be sure to wear comfortable shoes - tennis or hiking - no flip flops or heels. Wear sunscreen and a hat, and bring water !! This hike takes 1-2 hours, but is well worth it once you get to the top!

This place is Breathtaking! Simply amazing. If you love to hike this is a great place to come to.

Brilliant views after a mile long hike up. First third is paved, then hard packed trail with gentle incline. The bunkers built into the hill are an interesting site!

The view is worth the trip to the top. The stairs are the most direct, but most tiring way, so you might want to try the other path.

Great work out going up! I suggest do not bring little kids, this is hard climb for them. Once up there, the view was awesome! Bring water to drink!

Great view over Waikiki on top I was here last week that hike was crazy and fun. Wear comfortable footwear, no slippers and bring some iced cold water.

Amazing hike , great view . They sell cold water bottles, if you forget to bring one. Also, cold smoothies . Accessible by The Bus from Waikiki.

One of the best hikes in Oahu! We could see some people in sandals; I wouldn't advice it though.Excellent views from the top.

Beautiful view . Parking very limited and you'll only know spaces have filled up once you arrive at entrance. Some parking before tunnel but advisable to keep your cars at home.

Worth it. Whatever it takes for you to do this, don't miss it. The views are SPECTACULAR!

Fun climb. Bring water if you're not a hiker, it can be a challenge for children and older people. Parking costs $5. Worth it!

Bring water ! The stairs are tight and if you are tall (I'm 6'2") you will have to crawl out of the observation point at the top of the spiral stairs on hands & knees. Beautiful scenery @ the top.

Another must-do when in Honolulu. Fairly easy hike (less than 1 hour up) to get great view over Honolulu.

Hike this famous monument and see spectacular views of Oahu’s south shore. Did you know that Mount Leahi, or Diamond Head, is an extinct volcanic crater formed 300,000 years ago? http://bit.ly/I6r4oC

The view is awesome,be ready to have a long walk to get on the top.

Wear comfy shoes . The climb is not over-taxing. If the long staircase appears daunting, you can take the exit route to the top.

Easy walk from Waikiki, 45 mins - 1 hr. Great views then a half hour hike into the crater. Watch out though the park closes at 6pm! Don't arrive too late.

Takes about 30-45 minutes to hike up. I would usually say go early but there are big tour groups that also go at the opening time. The top is pretty empty once they leave.

Great view of oaku island . It is possible to appreciate waikiki beach and its many hotels buildings

Beautiful hike best done early.

It's a very doable hike so grab some water and take your time. Also, once you're out of the tunnel take the new outdoor route to the top.

BRING WATER !!! There are plenty of places to rest so don't be afraid of the trek. Totally worth it once you are at the top.

Awesome views . If you plan to hike you'll need a couple of hours at least. Bring sunscreen .

Start at the beginning of the day ( 6 AM) when it's not really hot before the crowds and tour buses , wear good walking shoes (not "slippahs"), bring water , watch your footing on the uneven pathway.

Great hike to start the day. The outlook on top is congested with tourist - take a pic can't linger too much.

Started at 8:30am and finished at 9:45, which still gave enough time to finish before it got too hot. It's a mild hike but definitely a good exercise.

Hike the 300,000 years-old crater and take in the amazing view of the famed Waikiki coastline. Once you conquer the uphill hike , it’s smooth sailing on the way down!

Go whenever you want. So what if you're hot and sweaty? Being at the top with an amazing 360 AND a cool breeze is completely worth the sweat to get there.

Wear comfortable shoes with traction and brig lots of water.. If you're claustrophobic the tunnel might be as far as you go. The view is beautiful although climbing out you have to bend low

Their right, the best time to go here is in the morning it's getting hotter and hotter bring water and hades protect your eyes, there is a tricky part when you reach the top be prepared:)
