Mount Hehuan (; also called Joy Mountain) is a mountain in Central Taiwan. The peak lies on the border of Nantou and Hualien counties and is located within the far west of Taroko National Park. Hehuanshan is a popular destination in central Taiwan as the trail to the summit is wide, paved, and gradual, and only takes around 1.5 hours round-trip yet offers 360 degree views above the surroundings. The 3,421-metre east peak and 3,422-metre north peak of Hehuanshan are both higher than the main peak.
