This legendary climb begins in the city of Hilo and ascends to the summit of Mauna Kea. It's a breathtaking 13,800-foot climb into the clouds, a challenging 42-mile undertaking. Leaving Hilo's streets, you transition onto Kumana Drive, which merges into Saddle Road, or Hawaii Route 200. This scenic highway, a twisting two-lane road connecting the east to the west, takes you through a stunning array of landscapes: verdant rainforests, lava fields, desert-like plains, rolling grasslands, and ocean views. The saddle marks the point where you rise into the clouds. The last ten miles are a moon-like terrain where you'll find telescope and viewpoints. The summit's thin air and the road's steepness create a brutal final push, demanding every last bit of your energy!

Kaumana Cave is a lava tube that is free to enter. It was made by an 1881 lava flow from Mauna Loa volcano. The lava tube has been measured at just over two miles long, which ranks it as the 57th longest lava tube in the world. There is a warning sign at the entrance that indicates: "no lights, no walkways, sharp and loose rocks". Visitors should heed the warning and bring good shoes and a light.

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.
