You can boil an egg in minutes in the 80 C water of the Mae Ka Chan hot springs located in Chiang Rai province. The water from the main geyser is too hot for bathing, so instead there are separate pools where you can soak your feet in the naturally warm water and relax amid the gardens.
Mae Ka Chan hot springs is a popular rest stop for people traveling between the cities of Chiang Mai and Chiang Rai. In addition to the hot springs, you’ll find washrooms, souvenir shops, restaurants, food vendors, and people selling raw eggs to boil in the hot springs!
The Mae Ka Chan hot springs are located about halfway between Chiang Mai and Chiang Rai near the junction of highways 118 and 120. Public buses traveling between the two cities frequently stop here.
