Onomea Trail follows the alignment of the old government road into Hawaiʻi Tropical Botanical garden and splits at Alakahi Stream; one branch turns right to Kukilu Bay and the other continues directly across the garden to the east side of Kahaliʻi Stream. The stream may be forded at this point to connect with the Donkey Trail. Donkey Trail goes directly to the point between Kenenue and Kahaliʻi Bays. It is steep, with the tread uneven and often slippery. Use caution. Donkey Trail is part of a Hawaiian Kingdom government cart road used for hauling goods from the landing at Onomea.
