Best Scenic Drives on Hawaii #1: The Saddle Road...Kona to the Summit of Mauna Kea, Kaumana Cave and Hilo

Across the Roof of Hawaii

by Donnie MacGowan

Recent improvements to the Saddle Road make it no longer the grinding, intimidating drive it once was and open hundreds of square miles of unimaginably beautiful, strange and wondrous landscape to the Hawaii Island Visitor.

Approximate minimum time start to finish (to see every site): 12 hours

From Kona take Highway 190 to Highway 200 in 45 minutes of driving. Saddle Road, which cuts between the "saddle" of Mauna Loa on the south and Mauna Kea to the north, passes through ranch lands and the Pohakuloa Military Training Facility, for another 45 minutes, to the turn for Mauna Kea Access Road (John Burns Way). Nearby, Kipuka Huluhulu, or "shaggy hill", is a 20 minute hike to the top and back. From here it is a 30 minute drive to the Mauna Kea Visitor Information Center. The small village is home to scientists and astronomers that work in the observatories and an amazing place to learn what their research tells us about our universe. Returning to Hwy 200, drive 45 minutes to the amazing Kaumana Cave lava tube, a short hike and a wonderful exploration. A further 30 minutes down Hwy 200 brings one to downtown Hilo, where there are shops, restaurants, fine museums, gorgeous waterfront beach parks and a fabulous Farmers Market. From Hilo, it is approximately three hours to return to Kailua Kona over Hwy 200; alternately one can take the faster though less scenic Hwy 19 to Waimea and then Hwy 190 into Kailua Kona, about a 2 1/2 hour drive.

Leg 1) In Kailua Kona, start at Ahu’ena Heiau; take Palani Road east to Hwy 190; take Hwy 190 to jct with Hwy 200, The Saddle Road

Ahu'ena Heiau and Kamakahonu Beach

Centuries ago the inhabitants of this region built a series of sacred temples, or heiau, which were originally used for the purpose of sacrificing human beings to their war god, Kuka’ilimoku. This particular archeological site is called Ahu’ena Heiau, which in Hawaiian means “Hill of Fire”.

Built originally in the 15th century and rededicated by Kamehameha the Great in the early 1800s as the main temple of his capital, the current structures seen at Ahu’ena Heiau were re-built in 1975 under the auspices of the Bishop Museum with financial help from the Hotel King Kamehameha and are constructed to 1/3 the original scale. There are restrooms and showers located on the pier near the beach. Adjacent Old Kailua Town is a treasure of shops, restaurants and aloha.

Saddle Road

Crossing the spectacular saddle between the towering bulk of the volcanoes Mauna Kea and Mauna Loa at about 6600 feet, The Saddle Road runs through brush, grass and forest lands, over lava fields and through some of the wildest and most breath-taking scenery on the Island. From this roadway, four of the 5 principal volcanoes that form The Big Island may be seen: Hualalai, Kohala, Mauna Loa, and Mauna Kea. Because the western half of the road is in notoriously poor condition and consists, in reality, of only one operable lane for much of its descent from the saddle to the Mamalahoa Highway.

However, this road provides the only road access to the Mauna Kea Summit Area and Visitor Information Center, Mauna Kea State Park, Pohakuloa Training Area, Mauna Kea Astronomical Observatory Complex, Waiki'i Ranch and the Kilohana Girl Scout Camp. The Saddle Road also provides the only access to thousands of acres of public forest and open grass lands. Connecting Hilo from about milepost 7.8 on the Hawai’i Belt Road to the Mamalahoa Highway approximately 6 miles south of Waimea, the Saddle Road is widely used by island residents for cross-island travel, despite its somewhat poor condition and undeserved, evil reputation.

The Saddle Road frequently has perfect weather, but also fairly routine are patches of intense rain, fog and high winds. It’s takes about 2 ½ to 3 hours straight driving time, depending upon weather, to make the full traverse from Kailua Kona to Hilo; however, one should be sure to leave time in the schedule to drive up to Mauna Kea Visitor Information Station or hike the Pu’u Huluhulu nature trails.

Along its entire 53 mile length between the turn-off from the highway just 6 miles west of Waimea and where it meets Hawaii Belt Road just north of Hilo, there is no gas and there are no services available; plan accordingly. Some food, water and restrooms may be available at the Mauna Kea Visitor Information Station which is a 30 minute drive up a side road off the Saddle Road about half way.

Leg 3) Off a Spur road at the jct of John Burns Way and Hwy 200, on the south side, is Kipuka Huluhulu ("Shaggy Hill") Nene Sanctuary.

Pu’u Huluhulu Nature Trails/Kipuka Aina Hou

Frequently described as simultaneously the most noticeable and the most overlooked landmark along the Saddle Road, Kipuka Pu'u Huluhulu rises more than 200 feet out of the surrounding lava flows. It’s name meaning “furry hill”, this forested cinder cone has multiple trails winding up through rare native koa trees to breathtaking 360° views of Hualalai, Mauna Kea and Mauna Loa at the top, where you can also wander a meadow of native Hawaiian plants recently reintroduced in this protected natural habitat. By whatever trail, the summit of Kipuka Huluhulu is only about 20 minutes walk from the car.

Owing to the encapsulated nature of the kipuka, bird watching here is particularly fabulous; the Ā'akepa, Nene and the Ā'akiapola Ā'au, as well as the Kalij pheasants, pueo, i’o and turkeys are among the rare, endangered or just plain beautiful birds you will see here. The numerous roads and trails through the hundreds of square miles of adjacent lava flows makes for interesting, if hot and dry, mountain biking and hiking.

Parking and a unisex pit toilet are the only amenities available at Kipuka Pu’u Huluhulu.

Leg 4) Go north on John Burns Way to Mauna Kea Visitor Information Station.

Mauna Kea Visitor Information Station

The Visitor Information Station is open daily from 8 a.m. to 5 p.m. During the day there are interactive computer exhibits about Mauna Kea, the observatories and astronomical research, plus there are video presentations and nature trails to hike. Many evenings after dark National Park personnel and astronomers put on public programs and discuss what the latest astronomical findings tell us about the nature of our universe. The souvenir shop has some food items, including hot chocolate, coffee and hot soup, for sale.

Leg 5) John Burns Way to Mauna Kea Summit

Mauna Kea Summit

Before you decide to go to the summit of Mauna Kea, stop, think, plan. Are you prepared for cold and high altitude? Do you understand the nature and dangers of altitude sickness and UV radiation? Are you experienced at traveling icy dirt roads? Is you car safe for the trip (many car rental agencies on the island forbid you to drive this road)? The Rangers at the Visitor's center can brief you on altitude sickness, UV radiation preparedness, the condition of the road and all other information you need to decide whether to visit the summit (see a video here).

The summit of Mauna Kea is truly an amazing place. Beautiful, awe-inspiring, 360 degree views of the entire Big Island, the summit is also culturally and religiously important to the native Hawai’ians and is home to several, world-class astronomical observatories and their support buildings. Because of the extremity of the altitude and the poor quality of the road above the Visitor's Center, it is advised that extreme caution be exercised in deciding to visit Mauna Kea's Summit. From the road's end very near the summit, a short, 10 minute trail leads up Pu'u Weiku cinder cone to the actual mountain top and a Hawaiian religious shrine. Also near the summit is the 1-mile hike to Lake Waiau, the 7th highest lake in the US, as well as numerous archeological sites. Moving at altitude is strenuous, so conserve energy. Do not over-tax yourself, be sure to drink plenty of fluids and protect yourself from the sun, wind and cold. Leave the summit area and return to the paved road long before you are tired.

Leg 6) Return John Burns Way to Hwy 200; take Hwy 200 east to Kaumana Caves

Kaumana Caves

A skylight opening to 25-mile long Kaumana Cave is located at the county park near the 4-mile marker on the Hilo side of the Saddle Road. Concrete stairs take you down through the rain forest jungle to the bottom of a collapse pit forming two entrances to the cave. Most people are drawn to the entrance on the right, a large, opening leading to cavernous rooms. In this entrance, graffiti from hundreds of years ago to the present is preserved, scratched into the rocks. The entrance on the left, however, is more interesting, leading through squeezes and low spots to numerous rooms with fascinating speleo-architecture and cave formations. Both caves go to true dark in fewer than 300 feet in either direction. There are more than 2 miles of easily accessible, wild cave to explore here, but if you intend more than just a cursory inspection near the entrances, bring a hard hat, water and at least 3 sources of light. A quick tour of the caves takes fewer than 20 minutes.

Parking for the caves is located across the highway from the park; extreme care should be taken when crossing he road. Public restrooms, water and picnic tables are available at the park. As you approach Hilo from Kaumana Caves, Hwy 200 becomes variously called Kaumana Drive, then Waianuenue Avenue.

Leg 7) Take Hwy 200 into Hilo Town.

Hilo Town

Beautiful but wet, metropolitan but decrepit, bustling but laid back, Hilo is a lovely, maddening, heartbreaking, addictive study in contrasts. In can rain all day long for 50 days in a row, yet when the sun does shine, the views of Mauna Loa and Mauna Kea from the Liliuokalani Gardens, or of Hilo Bay as you drive down from the mountains, or the rain-forest and waterfall choked gulches with lovely beaches along the highway north of town, make Hilo one of the most truly, achingly-lovely spots on earth.

More laid back and sleepier than bustling Kailua Kona, Hilo is the largest town on the island, and the county seat. The Imiloa Astronomy Center of Hawaii, Tsunami Museum, Lyman House Missionary Museum and the Panaewa Rainforest Zoo are all wonderful places to learn about various aspects of Hawaii. There are numerous shopping districts, two large malls and the Historic Old Hilo downtown shops to browse through, a variety of sprawling green parks, a fabulous tropical arboretum right downtown and a mile-long black-sand beach fronting the bay to explore. Hilo's Farmer's Market is a "must see" for any visitor who is spending time on this side of the island.
