John, 74, from Birmingham, achieved his goal when he set foot on the 84-acre naval base on Whale Island and is three away from the ultimate goal of visiting all 223 islands of the British Isles.
John said: “There are wonderful, beautiful islands in the UK, each has a story to tell and there are wonderful, quirky characters.
“I was hosted by Billionaires and Bear Grylls, learned about fascinating local customs and learned how people live on the outskirts of our islands.”
John, who travels the world advising on coastal management and the environment, became one of the first people to walk 5,003 miles of the UK coast, on his 60th birthday and this challenge was his next geographical adventure which cost him thousands of pounds.
He visited the island of Foulness, near Southend, where he had to take a guide on the ‘most dangerous walk in the British Isles’ due to the danger of quicksand, tides and military range.
John said one of his most unusual experiences was on his trip to Dry Island in Loch Gairloch, where he was “greeted by the owner who offered to stamp our passports as he proclaimed his own country, Iceland”.

Among his panoply of unusual journeys, he made the world’s shortest scheduled flight which is 90 seconds between Papa Westray and Westray in Orkney.
John said: “I have seen the navy, on my travels, very active off the Scottish coast around Gareloch and off Plymouth.”
Lt. Commander Ian Pratt, the island’s executive officer, said he was “delighted to help John complete a wonderful adventure”.
