Richard Lyon, who was diagnosed with prostate cancer in 2012, was met by his wife and one of his two sons as he tackled his final hill, Ben Klibreck. He has walked, cycled and sailed about 745 miles during the challenge, taking his tent with him and camping during his journey.
Mr Lyon, from Ayrshire, said he felt relief after reaching the top and playing his final composition, one of 150 jigs and reels he has performed in front of fellow hillwalkers during his challenge.
"I just felt relief mainly," he said. "That might change after a couple of drams."
Mr Lyon has a target of £10,000 for his Fiddling the Munros challenge, which is raising funds for Friends of the Beatson and Prostate Cancer UK.
He came up with the idea while receiving radiotherapy for his cancer. He has been climbing Munros and Corbetts every day since April and performing a newly-composed tune to mark each achievement.
"It's a been a great experience and I've met some great people doing it," he said.
