Doi Inthanon National Park

Thailand’s highest peak is the country’s premier montane birding site, delivering cool-climate specialties you won’t see elsewhere. Work the summit boardwalk and Km 37–46 trails for Green-tailed and Mrs. Gould’s Sunbirds, Himalayan Bluetail, Ashy-throated Warbler, and highland laughingthrushes. Lower elevations hold bulbuls, minlas, and wintering thrushes, while waterfalls and mossy gullies shelter flycatchers and occasional pittas. December to February is prime for high-altitude species and mixed flocks; March to May brings breeding activity and vocal broadbills lower down. Start at first light, move downslope as the morning warms, and consider a licensed Chiang Mai-based guide for current stakeouts and best trail sequences. Bring warm layers, a rain shell, and watch for fog that can shift bird activity quickly.
