Sharn Iona Hughes, 58, from Prestatyn, North Wales, was killed in a collision with a Volvo “whilst attempting to see the lights” from Gwrych Castle.
The castle is the location for this series of I’m A Celebrity… after the Covid pandemic meant the filming could not take place in Australia as usual.
Locals have flocked to get a view of the castle, which has been illuminated for the show.
Ms Hughes was on a stretch of the busy A547 Abergele Road when the incident happened at 5pm on Saturday evening.
Her family said in a statement: “Sharn passed away on the 21st November …whilst attempting to see the lights at Gwrych Castle.
“Her family and friends are in total shock and perplexed by her tragic death and wish to say the following about their loss.
“Sharn was so selfless, and had such a joyous, charitable attitude to life. She was in the process of organising deliveries of hampers to the local food bank through the Women’s Institute. We’ll miss her kindness forever.
“Her curiosity led to her wanting to see the lights at Gwrych Castle which unfortunately led to her untimely tragic death along a very busy road. We are truly heartbroken.
“She was hoping to take a photo and send it to a friend. We know that several others will have done and plan to do the same. We urge people to take so much care and remember it is a busy main A class road.”
Ms Hughes was also a prominent member of the Womens’ Institute.
The WI said in a statement: “She was very active in the community, she was very generous with her time, and just generous in total, she put other people first and was a born organiser.
“She belonged to two WI’s, was treasurer of Gallt Melyd Church, helping to organise collections for food banks and recently very proudly finished the couch to 5k.”
