Tips from the Community
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.

From here you can see amazing views over Kuilei Cliffs Beach Park and up the coast toward Kahala. On the east side of the parking area, look for the Amelia Earhart Marker, which recalls her 1935 solo flight from Hawaii to California.

Tantalus Lookout allows you to see all the way to Diamond Head in the east, and to Honolulu International Airport and Pearl Harbor in the west. This spot is particularly popular at sunset due to the west facing view. Once you get to the upper parking lot, you will have to push your bike a very short distance to get to the end of the lookout area.

In the 1820s, sailors discovered what they believed were diamonds in the rocks on the volcano’s slopes. Although the sailors’ diamonds turned out to be clear calcite crystals, the name Diamond Head has been associated with the crater ever since. The best view is from the left-hand side of the building!

This small park is a lessser known beach that many tourists don't know is here (hope I didn't spoil it :)). This secluded beach has views of blue water and the three islands just off shore.

Kawaiku'i Beach is a quiet park right off Kalanianaole Highway. In the evening, gorgeous sunset views can be seen, casting all sorts of colorful hues onto the nearby Koko and Hanauma Bay craters. The park is perfect for a picnic at one of the tables or under the shelter. Many large trees also provide plenty of shade on the grassy lawn. There are also restrooms and a freshwater rinse shower available for use.

This lookout provides a stunning view of Makapu'u Point and Makapu'u Beach surrounded by rocky edges. You may have to walk with your bike from the parking lot to the lookout spot, but it's very short!
