We traveled to Oahu for the first island of many and wanted to go to Diamond Head!! It's a nice state park and there is a gift store to buy water for your hike up to the top of the monument. The hike itself is a nice journey to the top with nice view of the crater and the beautiful ocean. When you finally get to the top, it has a magnificent view of Waikiki beach and so much more. Make sure you pick up a t shirt or two at the gift shop.

We booked reservations ahead of time and just printed the QR code. When we arrived, they just quickly scanned the code and we went right in, parked and started hiking. It was very easy and the views at the top are amazing!

Please know, if you are not a resident of Hawai’i, you have to make a reservation and there is a cost ($10/car and $5/person). This is not a hike. It is a climb. The path to the top is very clear and safe. There are some uneven places as you make your up. We had a 6am reservation and were able to see the sun rise! There were quite a few people at the very top so be patient as people are taking selfies, etc. I would definitely do this again.

The moderate hike to the summit with many steps takes less than an hour each way and you get great views. Note that all visitors from out of state MUST get an online reservation in advance or you will be turned away. It's only $5 and was easy to do. Be sure to take water and a hat.

We went early in the morning for sunrise. You can take the bus or drive up. We took the bus which made for a longer hike. Bring water especially if you are not used to a humid climate, parts of the hike are quite steep, especially the stairs. The views are definitely worth the hike up. When you get to the top, hang out a bit. Rainbows show up in multiple places if it's cloudy.

This was the first thing I did in Hawaii. Incredible views with plenty of lookout points along the way. Feels like every time you turn a corner, there's a view that's even more incredible than the last. A great hike for people of all ages and abilities. I like that reservations are required, and they're capping the amount of people allowed at any given time - means the path and lookout points don't get overwhelmingly peopled.

Best to come in the morning - even with our booking at 10am there were still a lot of people but it wasnt too crowded. Great views and a marvelous hike over all. Lots of steps and uphill walk but well worth it. Booking is a must. Took us about 1.5 hrs to complete but that was with a few stops for photos

We reached the park with a tour company who had organized the entrance tickets. The walk is somewhat challenging but even with my balance issues and the need to use walking poles, I was able to make it. Near the top, there are two options: one that is more gradual and one that is straight up reasonably steep stairways. Were I to do it again, I would go up the steep stairways as the more gradual route was completely in the sun and the stairways were in the shade.

It was 4pm when we climbed up, and it was a little bit hot when hiking up the mountain, but it was the perfect weather when we went back down. There were a lot of rocks and uneven surfaces so you should watch your step at all times. There are multiple picture taking spots along the way which is very convenient. Near the top, my daughter got a little scared because of the height but the view was amazing. It is a must see when visiting Hawaii.

Cool walk up the side of a volcano to some amazing views with some great history. The website made the walk sound hard but it was super easy for me (25minutes up). Those from NZ who are used to doing hiking will find this super easy. Recommend going early in morning so you beat the heat & see the sun coming up. You can Uber from Waikiki to the diamond head tunnel for about $12-14 USD & then I walked back to Waikiki afterwards - was a long walk but down hill or flat and lots to explore so if you’re into that makes it cheaper. Make sure you register online using the official website - you must have a prepared registration. Great morning had!
