Onomea Bay, Big Island

Onomea Bay is one of the lushest areas on the Big Island. The Hawaii Tropical Botanical Garden is located right on this bay and features waterfalls, streams and a raised wooden boardwalk leading to the ocean.

The bay is located just a short drive north of Hilo and is considered by many to be an area not to be missed. Past mile marker 7, the 4-mile (6.4 km) scenic drive on the Old Mamalahoa Highway begins. Make a stop at the botanical garden and do a self-guided tour.

You’ll come across over 2,000 exotic types of flora. The lush garden is also home to many birds, and you’ll be breathing air that is filled with the fragrance of tropical flowers and fruits. Onomea Falls is located on the grounds as well.

If you don't want to pay the entrance fee to the garden to hike down to the bay, you can see Onomea Bay from a lookout (located along Mamalahoa Highway).
