Gukeng navel oranges are the citrus fruit grown in Gukeng Township, Yunlin County, which multiple reports confirm as Taiwan's single largest navel orange growing region, with over a thousand hectares under cultivation; its national production share fluctuates by year, reported at roughly one-quarter to two-fifths. The large day-to-night temperature swings and abundant rainfall on Hebaoshan produce thin-skinned, juicy fruit, with the harvest running from November to February.
Reports from United Daily News (聯合新聞網) and others show Gukeng Township's navel orange growing area reached 1,032 hectares (2026 data), the largest in Taiwan, with annual production of over 30,000 metric tons; coverage notes roughly one in four navel oranges nationwide comes from Gukeng, while some local sources cite a share of nearly two-fifths — the discrepancy stems from differing years and metrics (area vs. output), though "Taiwan's largest producing area" is consistently confirmed across sources.
What are Gukeng Navel Oranges
Navel oranges (Citrus sinensis) belong to the sweet orange family — thin-skinned, juice-rich, and balanced between sweet and tart. Farmers in the Hebaoshan area of Gukeng began large-scale cultivation in the 1960s, selecting local varieties adapted to the mountain climate. Common ways to enjoy them include eating fresh out of hand, hand-pressing for fresh-squeezed juice, or buying processed goods such as orange cookies and orange doughnuts; the township farmers' association also carries orange jam and orange enzyme drinks.
Gukeng Township is known as the 'coffee township,' and Hebaoshan presents an agricultural landscape where coffee and navel oranges coexist — coffee grows at higher elevations while oranges concentrate on the gentler mid-slope terrain. The Yunlin County Government's Agriculture Department has confirmed that Gukeng accounts for nearly two-fifths of Taiwan's navel orange acreage. The annual winter festival draws large numbers of visitors to pick fruit directly at orchards, making it a key agri-tourism event for Yunlin County.
