The Akaka Falls are worth seeing even when it rains.

Akaka Falls State Park is located on the northeastern Hilo Coast and features two magnificent waterfalls. The 0.6 km long, gently ascending hiking trail takes you through a lush rainforest with wild orchids, bamboo groves and hanging ferns. If you continue following the paved footpath, you will first come across the 30 m high Kahuna Falls. Behind the next bend in the circular route you can already see the towering Akaka Falls, which plunge over 135 m into a gorge. The beautiful waterfall is probably the most famous of its kind on Hawaii Island. The pleasant hike takes less than an hour. https://www.gohawaii.com/de/islands/hawaii-big-island/regions/hilo/akaka-falls-state-park

From here, visitors can take the Onomea Bay Trails down to the bay. The bay on the ocean is about .4 miles from here on a boardwalk. The walk through the lush rainforest brings visitors to lush forests with so much green foliage and flowers and past waterfalls. Be careful because this area can get very slippery when wet, so wear proper shoes and try to let the trails dry out after it rains. Even if they choose not to go down the trail on foot, bikers can peer down the trail from the parking lot and find a few memorial statues without having to hike.

Onomea Bay has an amazing view of rocky shores, crashing waves, and a nice viewing platform. The waters are a bit too rough to swim, especially with all the lava rocks. The jungle surrounding the shores and trail are amazing with flowers and thick vegetation.

Onomea Bay is located close to the Hawaiʻi Tropical Garden and is the perfect combination of jungle and the ocean. The views along the Onomea Bay Trail will bring you to multiple beautiful viewpoints to enjoy the views of the bay.

Yes, the region offers several easy hikes perfect for families. A great option is the Onomea Bay Trail — Hawaiʻi Island, a short and scenic path that descends through beautiful tropical vegetation to the coast. It's less than a mile long, making it manageable for hikers of all ages.
The Hilo Forest Reserve is on the windward side of the island, which receives frequent rainfall. Trails are often muddy and can be very slick. It's essential to wear sturdy, waterproof hiking shoes with good grip. The dense rainforest canopy keeps the trails shaded and cool, but also damp.
While the reserve itself is more known for its dense rainforest, the nearby ʻAkaka Falls State Park is famous for its waterfalls. You can see the impressive 442-foot ʻAkaka Falls and the 100-foot Kahuna Falls on a short, paved loop trail within the park. It's a must-see for waterfall enthusiasts visiting the area.
For general day hiking on marked trails, permits are not typically required. However, permits are needed for other activities such as hunting, camping, or accessing specific areas like the Keanakolu Bunkhouse. It's always best to check the official Department of Land and Natural Resources (DLNR) website for the most current regulations before your visit.
Given the wet and tropical climate, proper gear is key. Be sure to bring:
Absolutely. The reserve's native forests provide a critical habitat for many of Hawaiʻi's endemic birds. Birdwatchers can look for species like the ʻIo (Hawaiian hawk), ʻApapane, and ʻAmakihi. The Puʻu ʻOʻo Trail, which crosses old lava flows and enters ʻōhiʻa forest, is a particularly well-regarded spot for birding.
Access varies greatly. Some trailheads near Hilo are easily reached with a standard car. However, accessing more remote areas, like the trails in the Laupāhoehoe Section or near the Keanakolu cabins, often requires a 4-wheel-drive vehicle due to rough, unpaved roads. Always research the specific access requirements for the trail you plan to hike.
Yes, you can find loop trails in the area. For a very scenic and relatively easy loop, consider the Onomea Bay Viewpoint loop from Pāpa‘ikou. This trail offers beautiful coastal views and takes you through lush vegetation without having to retrace your steps.
The hiking routes in and around the Hilo Forest Reserve are highly rated by the komoot community, with an average score of 4.5 stars. Hikers frequently praise the incredibly lush, green rainforest scenery and the feeling of being immersed in a wild, natural environment.
Yes, for a rustic experience, the Keanakolu Bunkhouse and Ranger Cabins are available within the reserve at an elevation of 5,300 feet. These provide a base for exploring the more remote trails. Be aware that access is challenging and requires a 4WD vehicle. You can find booking information on the State of Hawaiʻi's camping reservation site.
Besides the main reserve, hikers enjoy several other natural areas. The Upper Waiakea Forest Reserve is known for its trails through lava fields and wildflowers. For a shorter, well-maintained walk focused on native plants and birds, the Kaulana Manu Nature Trail is a popular choice. The Pu'u O'o Trail is also a favorite, especially for birdwatching.
