Rainbow (Waiānuenue) Falls is a large waterfall, measuring 80 ft (24 m) tall and almost 100 ft (30 m) in diameter. It is free to enter and see the falls because this area is part of the Hawai'i State Parks. There is no fee to see the falls. Rainbow Falls gets its name from the rainbows that show around the falls, created by the mist from the falls and the sunshine at 10:00 a.m.

The Naha Stone was a sacred stone to test a member of a particular bloodline for leadership. Whoever could move the stone possessed the 'mana' or spiritual power to rule.

The 80-foot Rainbow Falls is a beautiful sight to see. While the falls itself is not safe for swimming, the pools above the falls are safe given the weather is good. Legends say that the cave beneath the waterfall was the home of Hina, mother of the demigod Maui.

Frequently Asked Questions

Are there any family-friendly hikes near Keaau?

Yes, the area offers several easy walks suitable for families. A great option is the Coconut Island (Mokuola) – Liliuokalani Gardens loop from Mokaoku. It's a short, relatively flat walk of about 1.7 miles (2.8 km) through beautiful coastal gardens, making it manageable for all ages.

Can I see waterfalls on a hike near Keaau?

Absolutely. For a memorable waterfall experience, consider the Liliuokalani Gardens – Rainbow Falls loop from Mokaoku. This trail leads you to the impressive 80-foot Rainbow Falls. The area around the falls is lush and tropical, offering beautiful scenery.

What are the trails like for hiking on lava rock?

Hiking on lava rock is a unique feature of the Puna district. The terrain can be uneven, sharp, and sometimes slippery, especially when wet. It's essential to wear sturdy, closed-toe hiking shoes with good grip. Take your time, watch your footing, and carry plenty of water as the dark rock can radiate heat.

Are there any dog-friendly trails in the Keaau area?

Many trails in the region, particularly those on public lands and in state parks, have restrictions on dogs to protect native wildlife and ecosystems. It's always best to check the specific regulations for each trail or park, such as the Historic Puna Trail, before you go. Service animals are generally permitted.

Where can I hike to a beach near Keaau?

The Ha'ena Beach and Sea Turtles – Kalele Palm Grove loop is a fantastic choice. This trail takes you through a lush palm grove to the secluded Ha'ena Beach, also known as Shipman Beach. It's a beautiful spot and a known resting place for Hawaiian green sea turtles (honu).

Can I explore any volcanic lava tubes or caves?

Yes, you can explore a massive lava tube at Kaūmana Caves State Park near Hilo. This popular natural attraction allows you to descend into a cave formed by a lava flow from Mauna Loa in 1881. Remember to bring a flashlight and wear sturdy shoes as the ground is uneven and dark.

What kind of wildlife might I see while hiking?

The region is rich in wildlife, especially birdlife. On coastal trails, you have a good chance of spotting Hawaiian green sea turtles (honu) resting on the sand. The rainforests are home to various native and non-native bird species. For dedicated birdwatching, the Hakalau Forest National Wildlife Refuge is a renowned preserve, though access typically requires a guided tour.

Are there any circular walks available?

Yes, several loop trails make for convenient hikes without the need to backtrack. The Liliuokalani Gardens loop from Waiākea is a pleasant circular route through the scenic Japanese-style gardens and along the coast near Hilo.

How difficult are the hiking trails in this area?

Most hikes around Keaau are rated as easy to moderate. The terrain is generally flat with minimal elevation gain, especially along the coast and through the gardens near Hilo. Some trails, like the Puna Trail to Ha'ena Beach, can be more challenging due to muddy conditions and uneven lava rock surfaces.

What should I know about parking at the trailheads?

Parking can be limited, especially at popular trailheads like the one for the Historic Puna Trail. It's a good idea to arrive early to secure a spot in the designated lot. In some cases, you may need to find parking along the road, so be sure to do so safely and legally, without blocking access.
