Pioneer Mill was located on the west side of the island of Maui and began production at the surprisingly early date of 1864.

Founded in 1860, Pioneer Mill in Lahaina in West Maui covered 600 acres (250 ha) on the Hawai'ian Islands. By 1876, tourmaui notes proudly, the mill "won an award at the Philadelphia World's Fair for its fine quality sugar.". A "mainstay" of West Maui's economy, the company had put 8,000 acres (3,333 ha) under cultivation by 1910. Eventually the mill harvested an area that was 10 miles (16 km) long and 1/2 mile wide (0.8 km) at elevations between 10 feet (3.05 metres) and 700 feet (213 metres).
"This land was so productive," added tourmaui, "that some fields could produce sugar cane without plowing or replanting for as long as 10 years! [emphasis in original]...At its peak in 1935, the plantation cultivated 10,000 acres and processed 60,000 tons of sugar."
