Doctor Napassaporn "Eem" Chamnansit, who became the first Thai woman to summit Mount Everest in 2016, announced last week that she made it to the top of the highest mountain in North America.
Dr Napassaporn, a dentist, wrote on her Facebook page that it took her an entire year to prepare to conquer Mount Denali.
She and her team began the journey to the top last month and reached the summit on June 28. The team started out with several members, but many dropped out along the way. By the end of the trip, there were just four people left. Her successful climb to the top of Mount Denali followed a failed attempt last year.
The peak, which is located in the US state of Alaska, was a tough challenge for her, she said. Fewer than 40% of climbers have managed to make their way to the top of the summit, which has an elevation of 20,310 feet (6,190 metres) above sea level.
The team said Dr Napassaporn spent the first half of last year training for the Denali project.
During her failed Denali attempt last year, she and her team faced extreme weather conditions and were stuck on the mountain for six days.
Dr Napassaporn added Mount Denali to her list of summits after having conquered six additional peaks including Mount Everest in 2016 and Mount Kilimanjaro, the highest peak in Africa.
