A father-of-four died in Benidorm after a fatal fall on his first ever holiday abroad.
Nathan Osman, 30, from Pontypridd, Rhondda Cynon Taf, “suffered a tragic accident” on Saturday morning, his family said.
In a statement, they said Mr Osman got lost while trying to return to his hotel.
His family, who have been left “utterly devastated and heartbroken”, said he took the wrong path which led to a fatal fall.
They said he had been “looking forward to his first trip abroad with friends” and emphasised “the importance of not walking home alone”.
Paying tribute to Mr Osman, the family described him as “the most doting partner to Katie” and his children “were his absolute world”.
“He was an incredible father and made so many wonderful memories that his children will cherish forever,” they added.
“Nathan was the most loyal person, a faultless son, a caring brother, a fun loving uncle and a true friend to anyone that was lucky enough to know him.”
His smile and eyes were “infectious” and “he was the kindest of souls”, his family said.
