McLennan had last been seen alive on Thursday 25 June with police, mountain rescue teams and other agencies beginning the search the next day.
His disappearance came amid record-breaking temperatures in Wales with 35.9C (96.62F) recorded in Cardiff on the day he vanished.
“It’s deeply painful knowing that he was alone on the mountain while we searched,” his family said.
“But early on Monday evening we finally found him and there is a measure of peace in that, not only for us but for his soul…
“Dad was a passionate and inspiring man whose warmth reached many people.
“Our friends and loved ones dropped everything, offering help in an awful time, something we’ll always be grateful for.”
