Kaupo Road
Maui's forgotten coast through ranch and lava country.
Kaupo Road traces Maui’s wild southeast shore through landscape that time forgot, where black lava meets turquoise Pacific and ancient Hawaiian settlements dot the coastline. This remote route winds past Huialoha Church, built in 1859 from volcanic rock, before climbing through Kaupo Ranch’s rolling pastures toward Haleakala’s slopes. The road alternates between rough gravel, washouts, and brief paved sections, with stream crossings that can turn dangerous during storms and stunning coastal views that stretch toward the Big Island.
High-clearance 4WD recommended, especially after rains when streams run high and mud turns treacherous. The route stays passable year-round for capable vehicles, but locals know to avoid it during kona storms. No services exist along this 37-mile stretch—bring water, food, and emergency supplies. Charles Lindbergh’s grave sits near the road’s end at remote Palapala Ho’omau Church. This journey delivers authentic old Hawaii, where you’ll see more cattle than tourists and experience Maui’s untamed backcountry spirit.

Frequently asked questions
Can I drive Kaupo Road with a stock Jeep Wrangler or Toyota Tacoma?
Yes, any high-clearance 4WD vehicle can handle Kaupo Road. The rough lava rock sections and loose gravel require 4WD and decent ground clearance, but nothing extreme.
Is Kaupo Road passable during Maui's rainy season?
The trail is generally passable year-round, but heavy rains can make the dirt sections muddy and the water crossings deeper. Check conditions after storms before heading out.
Do I need permits to drive the full Kaupo Road?
No permits required for the road itself, but respect private ranch land along the route. The road passes through a mix of state and private property with established right-of-way access.
What's the most challenging part of driving Kaupo Road?
The roughest section is through the lava fields where sharp volcanic rock can be hard on tires and the road narrows significantly. Drive slowly and watch your line choice.
How deep are the water crossings and should I bring recovery gear?
The stream crossings are typically shallow (under 12 inches) but can vary with rainfall. Bring basic recovery gear - the remote location means self-reliance is essential if you get stuck.
