Diamond Head State Monument, Honolulu (must see)

Diamond Head State Monument is a volcanic cone known locally as Leahi. The monument is located near Waikiki Beach. It is a must-see for tourists of Honolulu as hiking up the cone offers a beautiful, panoramic view.

The monument was named Diamond Head by British sailors who thought they had found diamonds but were disappointed to learn that the brilliant sparkle came from calcite crystals. The native name means "brow of the tuna."

It is thought that the crater was formed about 300,000 years ago from volcanic activity. It is 761 feet tall and covers a span of 350 acres.

The trail going up the cone can be a challenge, but those who make it to the top know it is worth the effort. There are two sets of stairs that are a total of 175 steps.

Tip:
Go early in the day – before the crowds and sun really kick in – and bring a bottle of water with you to stay hydrated. On the way up, you get to an intersection and you go left or right. Right takes you up stairs; instead, you can take the left, which is a bit more scenic and not as grueling.
