 In 1995, Groom became the fourth person ever to summit the four highest mountains in the world (Lhotse, Kangchenjunga, K2 and Everest) without the aid of bottled oxygen.
 He proceeded to climb the fifth-highest, Makalu, in 1999.
 In 1987 he lost the front third of his feet to frostbite descending from his successful summit of Kangchenjunga.
 Despite this, he later managed to summit Mount Everest in 1993 and again in 1996.

Kangchenjunga (Nepali: कञ्चनजङ्घा , "Kañcanajaṅghā"), also spelled Kanchenjunga, is the third highest mountain in the world, and lies partly in Nepal and partly in Sikkim, India.
 It rises with an elevation of 8586 m in a section of the Himalayas called "Kangchenjunga Himal" that is limited in the west by the Tamur River, in the north by the Lhonak Chu and Jongsang La, and in the east by the Teesta River.
Nanda Devi is the second highest mountain in India, and the highest located entirely within the country.
 (Kangchenjunga, which is higher, is on the border of India and Nepal.)
 It is the 23rd-highest peak in the world.
 It was considered the highest mountain in the world before computations in 1808 proved Dhaulagiri to be higher.
 It was also the highest mountain in India before 1971 when Sikkim, the state in which Kangchenjunga is located, joined the Republic of India.
 It is part of the Garhwal Himalayas, and is located in the state of Uttarakhand, between the Rishiganga valley on the west and the Goriganga valley on the east.
 The peak, whose name means "Bliss-Giving Goddess", is regarded as the patron-goddess of the Uttarakhand Himalaya.
 In acknowledgment of its religious significance and for the protection of its fragile ecosystem, the peak as well as the circle of high mountains surrounding it—the Nanda Devi sanctuary—were closed to both locals and climbers in 1983.
 The surrounding Nanda Devi National Park was declared a UNESCO World Heritage Site in 1988.
