Whether you are a virgin or not – you should go in a volcano while you are in Hawaii. You can go in Diamond Head or head over to the Big Island but my suggestion is that while you are on Oahu, you visit a geologic masterpiece on the south side of the island.
You can climb up Koko Head Stairs and then you can go take a cool down hike through the Koko Head crater. To get there you will drive from either the Honolulu side or the Kailua side. Between the two you will find Sandy’s Beach and that is where you’ll turn and drive through California looking suburbs, past a golf course, up to a horse stable and guess what…you’re there – inside the Koko Head Volcano. Look around and it will make sense, but when you drive in – you barely notice because one side of the volcano opens to the burbs.
What I love about this spot is th at it is generally off the radar – the yoga/hiking/Instagram selfie crowd like to go to the tops of the mountains, the old bus tourists stay on the well worn coastal roads and stops, and Koko Crater just sits like a jewel waiting to be discovered. Sixty acres of serene, colorful, fragrant and almost never crowded dryland botanical garden. Dozens of plumeria flower trees (frangipangi), bougainvilla, cactii, and Hawaiiian endemic species all abound with color and beauty.
The garden has been built since 1960 and is an ongoing and never ending project of the Honolulu Botanical Gardens. The climate in the crater is suitable for African, American, Hawaiian, and Madagascarian plants and cactii. There is a two mile loop trail with more than two hundred species on it. I usually spend a couple of hours there but I would recommend no less than an hour to enjoy it. Bring water and wear sunscreen. You don’t really have to worry about bugs here.
