Hilo to Maunakea Visitor Information Station

This is an extremely challenging ride. While the total duration is approximately 6.5 hours of active cycling, factors like fitness level, weather, and stops for rest or photos can significantly extend this. It's wise to plan for a full day.

No, this route is considered one of the world's most difficult climbs and is not suitable for beginners. It involves relentless uphill climbing from sea level to 9,200 feet (2,804 meters) with significant altitude challenges. It's best reserved for advanced and highly conditioned road cyclists.

The route typically starts from Hilo, at sea level. You'll need to arrange parking in Hilo, as there isn't a designated trailhead parking area for this specific cycling journey. Many cyclists start near the waterfront or a local park in Hilo.

The route is entirely paved up to the Maunakea Visitor Information Station. The initial section from Hilo to Mauna Kea Access Road (Saddle Road) has an average gradient of about 5%. The section from Maunakea Access Road to the VIS becomes significantly steeper, with average gradients of 8-9.5% and some sections reaching 13-17%.

The scenery dramatically transforms as you ascend. You'll start in the lush rainforest environment of Hilo, gradually transitioning through sub-alpine landscapes, and finally into stark, windswept volcanic terrain. Higher up, you'll experience breathtaking panoramic views of the island, often rising above the clouds.

The best time to cycle is generally during the drier months, typically from late spring to early fall (May to October), when the weather is more stable. However, conditions can change rapidly at higher elevations, so always check the forecast for both Hilo and Maunakea before you go. Be prepared for significant temperature drops as you gain altitude.

Yes, early in the ride, you'll pass near Kaumana Caves. As you climb, you'll get incredible Views of Mauna Kea itself, and the Maunakea Visitor Information Station serves as a significant landmark and rest stop.

While primarily a road cycling route, it does briefly intersect or run alongside sections of other paths. You might encounter parts of the Kaumana Trail, Kahinahina Road (R-1), Pu‘u ‘O‘o Horse Trail, and the Mauna Kea-Humu'ula Trail.

This route is not suitable for dogs due to the extreme elevation gain, harsh conditions at altitude, lack of water sources, and fast-moving traffic on sections like Saddle Road. It's best to leave pets at home for this particular adventure.

There are no specific permits or entrance fees required for cycling the paved road to the Maunakea Visitor Information Station within the Mauna Kea Forest Reserve. However, be aware of any specific regulations or advisories from the Maunakea Observatories or the Department of Land and Natural Resources regarding access or activities on the mountain.

Services are extremely scarce after leaving Hilo. There are no water or food stops for approximately 55 km until you reach the Maunakea Visitor Information Station. It is absolutely critical to carry all necessary water, food, and supplies with you, or ideally, have a dedicated support vehicle.

The rapid and significant elevation gain means altitude sickness is a serious concern. At 9,200 feet, there's significantly less oxygen. It's highly recommended to acclimatize to altitude if possible before attempting this ride. Individuals with health conditions, pregnant women, and children under 13 should avoid going above the VIS. Listen to your body, stay hydrated, and descend immediately if you experience symptoms of altitude sickness.
