I was bitten by the travel bug badly so this is such a difficult question! I think I’d have to go with when I summited Mount Kilimanjaro for Worldwide Cancer Research during my second year of university.
Although I was exhausted and experiencing some nasty altitude sickness, it was so worth it knowing I had raised so much money for a cause that’s close to my heart – and seeing the curvature of the earth didn’t hurt either!
I would never have had the courage to make the climb on my own so I’m so glad I joined the society that was organizing it when I was at university. That would be one of my top tips for anyone studying abroad: joining clubs and societies can open doors you never thought existed!
