Koko Crater Botanical Garden is a hidden gem and power spot in Hawaii where you can enjoy various types of flowers from around the world!
While Kilauea Volcano on the Big Island is famous for its ongoing eruptions, Oahu’s Diamond Head and Koko Crater were also volcanically active over 100,000 years ago.
The volcanic vent became a crater, which is said to have formed into its current shape about 40,000 years ago.
Koko Crater Botanical Garden is a power spot where you can feel the earth’s energy. Despite being the second-largest botanical garden on Oahu, admission is completely free!
It’s a highly recommended spot where you can fully enjoy flowers typical of Hawaii like plumeria, bougainvillea, and hibiscus, as well as unique plants and cacti you won’t see anywhere else!
The Trail at Koko Crater Botanical Garden

Koko Crater Botanical Garden is located inside a crater, and the entire area is laid out as a walking trail.
There’s a map of the garden at the entrance (you’ll find it inside a mailbox), so be sure to grab one if you need it!
You’ll also find information about the history of the crater and the plants you can see in the garden.
The full loop trail is about 2 miles (3.2 km) long and takes about an hour to walk. You can see a variety of trees not only from Hawaii but also from around the world, including Africa and Asia.
If you just want to do a quick loop near the entrance, it will only take about 15 to 20 minutes.
Even on the shorter walk, you can still enjoy plenty of plumerias, bougainvilleas, and hibiscuses!
The Plumerias of Koko Crater Botanical Garden

The most popular area in Koko Crater is the plumeria grove, where you can see over 100 plumeria trees.
It’s like a forest of plumerias, making it a true power spot where the scenery and fragrance will soothe you!
The plumeria blooming season is from May to October, so if you’re visiting Hawaii during this time, be sure to stop by.
At the peak of the season, you can enjoy the sweet fragrance of the flowers filling the air. When the blossoms start to fall, the ground becomes like a carpet of petals.

Here’s the classic yellow variety you often see in shops!

Many flowers bloom at eye level, making it perfect for taking photos.
By the way, women often wear these plumeria flowers behind their ears. Wearing it on the right ear means you’re single, while the left ear signifies that you’re married or in a relationship!
The Cacti of Koko Crater Botanical Garden

Along with the plumerias, another popular area in Koko Crater is the cactus garden, which is reminiscent of Arizona!
This section features native Hawaiian plants, cacti from the American mainland, and plants from the African savanna.
You might not associate Hawaii with cacti, but you can actually see a wide variety here, from small, round ones to tall, slender giants.
It’s a bit of a walk from the entrance, but you can reach it in about 15 minutes. Seeing this area and then heading back is one option.
The landscape might not feel like typical Hawaii, but its impact is absolutely breathtaking!
Other Areas of Koko Crater Botanical Garden

While the plumeria and cactus areas are the main highlights for most visitors, there are many other fascinating sections to explore.
Hawaii is home to many endemic species that have evolved uniquely, so plant lovers will find a continuous series of delightful sights.
We especially recommend checking out the unique plants you can only see here, such as Baobab trees, the native Hawaiian Wiliwili tree, and various types of palm trees!
