Easily Hawaii's most-recognized landmark, Lē'ahi, or Diamond Head, is the unmistakable profile you can see to the east from Waikiki. It got its name from Westerners who mistook the calcite crystals in the summit crater for diamonds. Lē'ahi is surrounded by almost 500 acres of Diamond Head State Monument, which is open only from 6am-6pm. If you are not a Hawai'i resident with Hawai'i ID, you must make advance reservations online before you visit; entry is $5 per person for non-residents, and $10 per vehicle if you are driving.

There's a separated pedestrian walkway in this tunnel, which offers some welcome shade as you walk up toward Kē'ahi (Diamond Head). Keep in mind that the tunnel and Diamond Head State Monument are only open from 6am-6pm. Authorities take that very seriously so if you stay after 6pm, you might be prosecuted for trespassing. If you are not a Hawai'i resident with a Hawai'i ID, you need advance reservations to enter the monument. Make them online via this website https://gostateparks.hawaii.gov/diamondhead ; they cost $5 per person and, if you're driving, $10 per vehicle too.
