2 Best Sights in Windward Oahu, Oahu

The name, which means "a peaceful refuge," describes the serenity and feeling of endless space you find in this verdant garden framed by the stunning Koolau Range. Its 400 acres contain specimens from such tropical areas as the Americas, Africa, Melanesia, the Philippines, and Hawaii. Not just for the botanist, Hoomaluhia has a 32-acre lake, easy walking trails, and open lawns ideal for picnicking and camping by permit. Families can also take advantage of the park's catch-and-release tilapia fishing program; free bamboo fishing poles are sometimes available for borrowing at the visitor center. If you see unusually dressed-up visitors, they are likely selfie seekers doing it for the 'gram. Hoomaluhia is very photogenic; just make sure you're not blocking the roadways in search of the perfect shot.

If you've visited any of Oahu's other botanical gardens, Koko Crater will stand in stark contrast. Inside the tallest tuff (a type of volcanic rock) cone on Oahu, in one of the island's hottest and driest areas, the garden showcases dryland species of plants, including baobab trees, cacti, plumeria, and bougainvillea. Bring plenty of water, sunscreen, and a hat. Though it's close to Oahu's more lush windward side, this is a scorching spot.
