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. Make reservations here: https://gostateparks.hawaii.gov/diamondhead

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.

This is a scenic lookout on the way up to the Lē'ahi (Diamond Head) trailhead. Walking to the trailhead is a great way to avoid the parking crush, especially since there's a bus stop not far away. Just beyond this lookout you'll enter the Kahala Tunnel, the customary pedestrian access to Lē'ahi. Keep in mind that unless you are a Hawai'i resident with Hawai'i-issued ID, you'll need advance reservations, which can be made online for $5 per person, plus $10 per vehicle if you're driving to the trailhead: https://gostateparks.hawaii.gov/diamondhead Also of note, the park is only open from 6am-6pm, and the last reservation for the day is at 4pm.
