Local Transportation: Mauna Kea

Public Transportation: Hele-On Bus

The Big Island's public transit system is the Hele-On bus. This system connects major towns like Hilo, Kailua-Kona, and Waimea, and offers some routes to attractions, though coverage is not comprehensive. For general tourist exploration, especially to remote sites like Mauna Kea's summit, the Hele-On bus is not the most practical option.

Route maps are on the Hele-On website. Consult for current schedules and routes. Major hubs include the Mo'oheau Bus Terminal in Hilo and the Kailua-Kona Pier. From these points, connections to various routes across the island are possible.

Fares & Service

Fares: Typically $2.00 per ride for adults. Daily and monthly passes are also available.
Payment: Pay with exact cash or a Hele-On smart card (purchased at various locations).
Service Hours: Vary by route; generally early morning to late evening, but frequency is low.
Accessibility: Hele-On buses are generally wheelchair accessible, providing services for travelers with mobility needs.

Budget-Friendly

Cost-effective for budget travelers, especially for specific routes within main towns.

Limited Coverage

Not for comprehensive island exploration or direct access to remote sites like Mauna Kea summit.

Low Frequency

Infrequent service makes planning multi-stop itineraries challenging and time-consuming.

Taxis & Ride-Sharing

Taxi Availability

Taxis are available on the Big Island, mainly at airports and major hotels.
You can hail taxis in larger towns like Hilo or Kailua-Kona, or call for pickup.
Typical fares are metered, but can be expensive for longer distances across the island.

Ride-Sharing Apps

Ride-sharing apps like Uber and Lyft operate on the Big Island, notably in the more populated Hilo and Kailua-Kona areas.

Rental Options: Cars & More

Car rental is the most common and recommended transportation option for exploring the Big Island and accessing Mauna Kea. Major car rental companies operate at both Kona International Airport (KOA) and Hilo International Airport (ITO).

Car Rental Requirements

Valid driver's license (U.S. Or an International Driving Permit with your national license for foreign visitors).
A credit card for payment and deposit.
Minimum age for rental is typically 21, though drivers under 25 may have a young driver surcharge.
Booking your rental car in advance is highly recommended, especially if you need a 4x4 vehicle for Mauna Kea access, as these can be in high demand.

Vehicle Types for Mauna Kea

A 4-wheel drive (4WD) or All-Wheel Drive (AWD) vehicle is generally a requirement by rental agreements for driving the unpaved section of the Mauna Kea Summit Road, which begins above the Visitor Information Station (VIS).
Driving a 2WD vehicle on this unpaved, steep, and often rough road voids your rental insurance and causes significant damage to the vehicle.
Many rental companies explicitly state this restriction. Verify your rental agreement carefully before attempting the summit road with a 2WD vehicle.
These specialized vehicles are in higher demand and can sell out, notably during peak seasons.

Estimated Daily Rental Prices

2WD Sedan (Economy): $60 - $120+
4WD/AWD SUV: $90 - $180+
Motorcycle and scooter rentals: Not recommended for Mauna Kea due to extreme temperatures, high winds, and gravel road conditions.

Bicycle sharing programs and rentals exist in some resort areas and towns; not practical for long-distance island exploration.
Driving laws: Standard U.S. Regulations; drive on the right side of the road, seat belts mandatory, speed limits enforced.
Parking: Generally available at tourist attractions, sometimes for a fee. Free parking at VIS and summit when accessible.

Driving Laws & Road Tips

Driving Side

Drive on the right side of the road, standard U.S. Regulation.

Seat Belts

Mandatory for all occupants.

Speed Limits

Enforced, observe posted signs.

Walking & Cycling

Walking is feasible within towns like Hilo or Kailua-Kona and within designated park areas. These areas often have sidewalks and are more pedestrian-friendly. Self-guided walking tours can be a pleasant way to explore historic districts or waterfronts. However, walking around Mauna Kea, specifically once you are on the Mauna Kea Summit Road, is limited to specific areas due to safety concerns. Bicycle infrastructure outside of some urban areas on the Big Island is limited. Dedicated bike lanes are not widespread, and cycling on main roads poses a challenge due to narrow shoulders and traffic volume.

Hiking Opportunities

Hiking trails exist on the lower slopes of Mauna Kea, like the Mauna Kea Trail, also known as the Humuʻula Trail, which starts near the Visitor Information Station (VIS).
This trail is a strenuous, high-altitude hike and calls for appropriate preparation and acclimatization.
Other areas of the Big Island offer numerous hiking opportunities, from easy strolls to challenging treks within Hawaii Volcanoes National Park or along coastal paths.
Water purification options: A personal water filter can prove useful for longer hikes on the Big Island where potable water sources are not guaranteed.

Cycling & Safety Zones

Cycling on the Mauna Kea Summit Road is not recommended due to its steep grades, unpaved sections, extreme temperatures, high winds, and vehicle traffic.
Specific "no-go" areas exist for pedestrians and cyclists for safety reasons.
The Mauna Kea Summit Road above the VIS is generally not recommended for walking or cycling.
Prioritize your safety and use appropriate transportation methods for each area.
