Diamond Head State Monument aka Diamond Head Crater

The Diamond Head Crater hike is a relatively easy hike but it's worth it when you reach the top. From the bottom here at the sign and without stopping for a breather, you can reach the top of the hike in about 25 minutes. However, there are many scenic stops along the way up that makes this hike take longer.
