Snow fell in the Chai Prakan and Mae Suai District areas of the range in 1955, a very rare event in these latitudes despite the altitude.

[9] The Khun Tan Tunnel was built in 1907 across the southern part of the range and contributed to alleviate the difficulties in communication between Bangkok and Chiang Mai.

Extensive wildfires are deliberately set off by local farmers in the mountain forests of the Khun Tan Range every year between February and April towards the end of the dry season.

These yearly wildfires are the main cause of the intense air pollution in Northern Thailand[15] and contribute to the floods in the country by completely denuding the undergrowth of the woods.

[17] Many species of mammals are assumed to have disappeared in the range for lack of recent sightings, such as the Asiatic black bear, the slow loris, the white-handed gibbon, the leopard cat and the serow.

Animals that have been sighted recently include civets, wild pigs, barking deer, hog badgers, flying squirrels and bats.

[19] Mae On District east of Chiang Mai is a popular destination for rock climbers who wish to climb the limestone cliffs of the place nicknamed "Crazy Horse Buttress" in the Range.
