Create an itinerary including Diamond Head State Monument
One of the first natural landmarks you see as you arrive in Honolulu, Diamond Head State Monument offers several vantage points with views of the entire island. Formed by volcanic eruptions more than 150,000 years ago, this tuff cone covers 141 hectares (350 acres). A well-beaten path leads partway to the top. Lengthy metal and concrete staircases make it easier to traverse the steepest sections, and the very narrow tunnels are illuminated. Climb to the summit if you feel fit, or enjoy the views from the lookouts along the way. Wear comfortable hiking shoes, and bring plenty of water and a snack.

  • Really enjoyed going up Diamond Head. Be sure to book your time slot ahead of time (this is quite new to control crowds) to ensure you get to go up! Despite this, still expect big crowds of people...

  • Great viewing point but the weather was not in our favour when we got there. The information boards were good so you could imagine where the other volcanos were!

  • There is a large field that is perfect for a picnic without going on the hike, if preferred (picture included). It was a moderate hike up to the summit, the slower you go the easier it is. The trail had plenty of places to rest and allow others to pass with plenty of photo opportunities. The hike back down was a breeze, just make sure you take some water and maybe a small snack and keep all your trash until you get back down. Highly recommended for the beautiful view of the crater and surrounding area at the top, also has an interesting history to read about!
  • Great, well maintained hiking trail. A little narrow in spots. Not hard at all. Actually one of the easier trails I've done across the country. Most people get up in 45 minutes. If you're really in shape, you can do it even faster. All shapes and sizes easily went up and down. Definitely wear trail shoes or shoes with good grip. A lot of steps towards the top, FYI. Go in the morning or around sunset to avoid biggest crowds. Bathrooms and water/vending machines at the visitor center. Just know that now you have to make A RESERVATION ONLINE to get into the park. $5 to hike. $10 if you want to park in the lot inside the park.
