Akaka Falls State Park

Akaka Falls State Park protects one of the most dramatic waterfall landscapes in the Hawaiian Islands, located along the Hamakua Coast of Hawaii Island (the Big Island), about 11 miles north of Hilo. The park centers on Akaka Falls, a free-falling 442-foot cascade that drops in a single unbroken plunge into a gorge thick with tropical vegetation. The surrounding rainforest, fed by consistent rainfall and volcanic soil, creates a dense, living environment that makes the short loop trail feel genuinely immersive rather than merely scenic.

Akaka Falls and the Gorge Loop Trail

The heart of the park is a paved 0.4-mile loop trail that winds through a rainforest gorge before delivering views of two major waterfalls. Visitors first reach Kahuna Falls, a wide, multi-tiered drop of roughly 100 feet, before continuing to the main overlook for Akaka Falls itself. The trail descends and curves through stands of bamboo, wild ginger, heliconia, and giant philodendron, with tree ferns and ti plants filling in the understory. Orchids appear along the rock walls in several places.

The overlook platform for Akaka Falls provides a clear, head-on view of the full drop into the pool below. There is no legal access to the base of the falls, and the trail does not descend into the gorge. The viewing experience is from above, which actually frames the full height of the falls better than a ground-level perspective would.

The loop is one-way and paved throughout, though it includes multiple steps in places, which makes it accessible to many visitors, including older adults and children who can manage moderate inclines and stairs. The pavement does become slick with moisture, so appropriate footwear matters. The entire loop typically takes 20 to 40 minutes at a relaxed pace, though many visitors slow down considerably to take photographs or simply spend time in the forest.

The Rainforest Environment

The rainforest at Akaka Falls is worth attention beyond the waterfalls themselves. This is a genuinely wet environment, receiving well over 100 inches of rainfall annually, and the plant life reflects that. Many of the species visible from the trail, including bamboo groves dense enough to block direct light, are introduced rather than native, but the overall effect of the landscape is striking regardless.

The constant moisture means the forest is never dormant. Ferns drape over rock walls, mosses cover every surface, and the air carries a heaviness that is noticeably different from drier parts of the island. For visitors coming from the sunny Kona coast or from the mainland, the shift in climate and vegetation within just a few minutes of driving inland is one of the more memorable parts of visiting the Hamakua Coast.

Pet Policy

Pets are not permitted on the loop trail or at the viewing areas at Akaka Falls State Park. Service animals are the exception and must remain under control at all times. Handlers should follow posted rules and clean up after them. Visitors traveling with pets should plan to leave them elsewhere before visiting the park.

Wildlife to Be Aware Of

The main health concern at Akaka Falls is leptospirosis, a bacterial infection spread through water or soil contaminated by the urine of infected animals, including feral pigs, rats, and mongooses. Visitors should avoid all contact with freshwater streams, standing water, and muddy areas throughout the park. The bacterium enters the body through breaks in the skin, the eyes, nose, or mouth. Staying on the paved trail significantly reduces exposure risk, and any cuts or open wounds should be covered before entering the park.

Feral pigs occur in Hawaii Island rainforests and may be present in forested areas around the park. They are generally not aggressive toward humans, but they are unpredictable wild animals and should not be approached or fed. If you encounter one on the trail, give it space and allow it to move away on its own.

The trail surface is a consistent hazard throughout the year. Rain falls frequently at this elevation, and the paved loop rarely has time to fully dry. Slipping and falling is a real risk, particularly on downhill sections. Closed-toe shoes with good grip are strongly recommended. Sandals and smooth-soled footwear are not appropriate for this trail.

Practical Information

Akaka Falls State Park is located at 875 Akaka Falls Road, Honomu, Hawaii. The nearest town is Honomu, a small community just off Highway 19 that serves as the turnoff point for the park road. From Hilo, take Highway 19 north approximately 11 miles, turn left at Honomu, and follow Akaka Falls Road roughly 3.5 miles to the parking area.

The park is open daily from 8:30 AM to 5:00 PM. Entry and parking fees apply to non-residents: $5 per person and $10 per non-commercial vehicle, with children 3 and under free. Payment is by credit card only. Hawaii residents with a valid Hawaii driver’s license or state ID are exempt from entry and parking fees. Parking is limited, and the lot fills quickly on weekends and during peak travel periods. Arriving early in the morning is the most reliable way to secure parking and have a quieter experience on the trail.

No reservations are required. Portable toilets are available at the trailhead parking area while the water and comfort station are closed. The park does not offer camping, picnic areas, or food concessions. Cell service can be inconsistent in the gorge area.
