Fees and Admission Hours of Operation

Visiting Koko Head Crater is a budget hike in Oahu as it costs nothing to park or hike at Koko Head Crater, unlike hiking Diamond Head– yet another popular crater on Oahu.

The park is open from sunrise to sunset, allowing hikers to start their day early or enjoy a sunset hike.

However, it’s advisable to begin your hike early in the morning to avoid the midday heat, especially for the more challenging trails like the Koko Crater Railway Trail. Then when you’re nice and sweaty be sure to find the perfect spot for snorkeling in Oahu to cool off.

The botanical garden follows the same hours, offering a peaceful and scenic route within the crater. Always check the local weather and park advisories before heading out to ensure a safe and enjoyable visit.

Koko Head Crater History

Koko Head Crater, also known as Kohelepelepe, was formed over 10,000 years ago during the Honolulu Volcanic Series.

The crater’s name has several interpretations, one of which is “Koko,” meaning blood in Hawaiian, possibly referring to the red cinder cone visible from afar.

During World War II, the crater played a crucial role as a military lookout point, and remnants of this history can still be seen today, particularly on the Koko Crater Railway Trail.

How to Get to Koko Head Crater?

Koko Head Crater is located at 423 Kaumakani St, Honolulu, HI 96825 on the eastern side of Oahu, in the neighborhood of Hawaii Kai.

The crater is part of Koko Head District Park, which also includes Koko Head Regional Park and Koko Crater Botanical Garden.

Directions

To reach Koko Head Crater from Waikiki, head east on the H1 Freeway, which eventually turns into Kalanianaole Highway (H-1).

Continue on Kalanianaole Highway until you reach the Hawaii Kai neighborhood. Turn left onto Lunalilo Home Road, then right onto Anapalau Street, and finally right onto Koko Head Park Road.

There is a parking lot at the base of the trail.

What Trails Are There to Hike at Koko Crater?

There are three trails you can hike at Koko Head which include intermediate to difficult hiking experiences.

Koko Head Botanical Gardens

Located within the crater, the Koko Head Botanical Gardens feature a 2-mile loop trail that is relatively flat and easy, making it suitable for all skill levels.

The garden is one of several botanical gardens on Oahu Hawaii and showcases various cacti, succulents, and dryland plants from Hawaii, Africa, and Madagascar. The garden’s unique desert-like landscape contrasts sharply with the lush tropical vegetation found elsewhere on the island.

Koko Crater Railway Trail

The Koko Crater Railway Trail, also known as the Koko Crater Stairs, is the most popular and challenging trail.

This trail follows an abandoned railway track that climbs 1,048 steps (or railway ties) to the summit of Koko Head Crater.

The trail is about 1.8 miles round trip but is considered difficult due to its steep incline and uneven steps.

Along the hike, you’ll pass old military bunkers and have spectacular views of Hanauma Bay, Diamond Head, and the east Oahu coastline.

The summit offers a panoramic view of the island, making the strenuous hike worthwhile.

Koko Crater Rim Trail

For those looking for a more rugged and adventurous hike, the Koko Crater Rim Trail is an excellent choice.

This trail follows the rim of the crater, providing stunning views into the crater itself and out towards the ocean.

The trail is about 3.2 miles round trip and is considered moderate to difficult due to the uneven terrain and exposure to the elements.

Hikers should be prepared for a mix of rocky paths and loose gravel, and it is recommended to start early in the morning to avoid the midday heat.

The rim trail offers unique perspectives of Koko Head and the surrounding area, making it a favorite among experienced hikers.

Conclusion

Hiking Koko Head Crater is an unforgettable experience that combines physical challenge with natural beauty and historical intrigue.

Whether you choose the steep climb of the Koko Crater Railway Trail, the scenic Koko Head Botanical Gardens, or the adventurous Koko Crater Rim Trail, you’re in for an adventure. Remember to bring plenty of water, wear appropriate footwear, and take your time to enjoy the stunning views. Happy hiking!
