Diamond Head State Monument is a cone that was formed by eruptions over 150,000 years ago. From overhead it sparkles like it is covered in diamonds, which is what drew explorers to it in the first place. The monument is on the southeast coast and it is easy to get to the monument form anywhere nearby, however, it should be noted that in order to actually see the monument you will need to hike up to it. It is quite affordable with a walk in fee of just $1, plus it is a great outdoor experience for the whole family.
