Lottie Fullerton was trekking on 10 August when she was hit by falling rocks and suffered a fatal head injury.
Miss Fullerton was reportedly descending towards Tatopani in Nepal’s Mustang region when the accident happened.
‘A friend to everyone’
Miss Fullerton went to Canford School in Canford Magna, Dorset. A service will be organised at Jesus College chapel in her memory.
In a statement the college said: “Lottie was a very popular member of the college and will be much missed by all at Jesus.
“A fellow student described her as ‘a friend to everyone at college’. Her tutors say she was an outstanding student, an excellent contributor, and a pleasure to teach.
“As well as being a hardworking and enthusiastic student, she played real tennis, went on the college ski trips and took part in the charity town and gown run.
“Our condolences are with her family, friends and all who knew her.”
Her friend Polly Lamming wrote an obituary to be published by the Cherwell student newspaper and said there was “no one in Jesus who does not love and respect her”.
She added: “Charlotte Fullerton was the best of people, and will always, always, be remembered as such.”
