The 26-year-old was on a trekking exhibition with his sister when the first earthquake hit and he described the event as frightening and violent.
�We were sitting outside our lodge in Dhunche waiting for lunch when the earthquake hit,� he said.
�We ran out on to the street and the ground started opening up.
�As the buildings shook we knew it was only sensible to run for our lives and exit the town.
�Nowhere was safe with a mountainous rise on one side of us and a steep cliff on the other.
�Rocks, soil and vegetation fell from above us as we left the town gates and tried to look for the safest place to go and then the earthquake subsided � it was the most terrifying two minutes of my life.�
The next three nights were spent in a refugee camp and while it was a terrible ordeal, Mr Williams said the open-hearted Nepalese hospitality eased the discomfort.
�Some townsfolk were making food for the entire camp, which swelled in numbers and others brought blankets and tents,� he said. �They did all of this with a friendly disposition and smiles on their faces, even though some people had lost their homes, friends, families and more.
�I feel indebted to them for all the help they provided during our time at the camp and along the treacherous road back to Kathmandu.�
Mr Williams is now organising a fundraiser on Saturday where $5 from every burger sold at Grill�d Scarborough will help raise much-needed funds for the Friends of Nepal charity.
�I fell in love with the country and its people,� he said.
�My holiday took an unexpected turn in the form of an earthquake and I was lucky to survive, but I love the environment and especially the people so much I would go back tomorrow if I could be of more use.�
Mr Williams also hopes to hold a fundraising music event this year.
