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 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.

Liliʻuokalani Gardens, named after Hawaiʻi's final reigning monarch, Queen Liliʻuokalani, stands as the most extensive authentic ornamental Japanese garden outside of Japan. This genuine 24.67-acre Japanese garden was inaugurated in 1917 as a tribute to the initial Japanese immigrants who worked in the sugar cane fields of the island of Hawaiʻi. This meticulously landscaped park boasts gracefully arched bridges spanning over serene fishponds, artful rock gardens, picturesque pagodas, traditional Japanese stone lanterns, and a tranquil tea house. The garden's ambiance is further enriched by panoramic views of Hilo Bay and Mokuola (Coconut Island), creating a serene and captivating setting.

Waiākea Forest Reserve offers a tranquil, often misty environment year-round. The best time to visit depends on your preference for weather.

Policies regarding dogs can vary by specific trail or park area. It's always best to check local regulations for each specific trail or park you plan to visit within the Waiākea Forest Reserve area to ensure dogs are permitted and if any leash rules apply.
Given the often misty and lush environment, comfortable hiking shoes, rain gear (light jacket or poncho), and insect repellent are advisable. Don't forget water, snacks, sun protection, and a camera to capture the beautiful scenery and potential rainbows.
