His college days in Darjeeling, with a view of the Sikkim hills and Kangchenjunga and its satellite peaks in the distance, exerted a strong influence upon him; he recounts in his writings that the view from Observatory Hill "never failed to arouse a mixture of excitement and desire: from Nepal in the west across Tibet and Bhutan in the east, 200 miles of snow- covered ranges, filled the horizon with Kangchenjunga as the centrepiece".

Trevor Braham's halycon years (1950–1972), corresponded with the "Himalayan Golden Age"[6] when an international frenzy developed to achieve the first ascent of the world's highest peaks.

In addition to his Himalayan climbing experience, Braham's knowledge of the local customs and language was invaluable to the Kangchenjunga reconnaissance expedition which was led by John Kempe in 1954.

[17] In 1958 Braham joined a small group, E. G. C. (Ted) Warr, the leader, Dr. Chris Hoyte, Walter Sharpley, and Dennis Kemp to attempt Minapin peak, 7,266 metres (23,839 ft), in the Karakoram (now called Diran).

[18] In his book Himalayan Odyssey Braham describes the trials and tribulations of bureaucracy, uncomfortable travel, dangerous roads, even more dangerous vehicles and drivers, spectacular flights, recalcitrant porters, the oasis charm of Hunza and "the magnificent peaks on both sides of the valley now traversed by the Karakoram Highway as it climbs to the Khunjerab pass on the Chinese border".

[3] Tragically, later in the expedition, after Braham had left early due to work constraints, Warr and Hoyte went missing and were presumed dead.

The story of its identification and eventual re-uniting with the daughter of Warr, one of the climbers lost in 1958, has been recounted by Shigeharu Inouje, an account which also included notes by Braham on the 1958 expedition.

"(The Effects of Change on Mountaineering Ethics) He has lectured to the Alpine and Himalayan Clubs, and to schools and societies in England, India and Switzerland.

[24] Braham continued to have an active life until the age of 95, when diminishing physical abilities required him to live in a nursing home in Gimel, above Lake Leman.

Erhard Loretan, who died in April 2011, a leading Swiss climber, and the 3rd person to have ascended the 14 highest summits of the world, requested Trevor Braham to translate into English his book, Himalayan Reflections, which was published in Switzerland in 1998.
