Their first attempt was in February, but, due to bad weather conditions, they had to postpone it.
Burns Maclear (67) and Koos Bouwer (66), left the farm in the Western Cape at 6.30am to start their walk to the mountain.
They were accompanied by filmmaker David le Roux and a guide known only as Allistair.
The 2 325m climb was rocky and bushy and they sometimes had to go on their hands and knees to get to the top.
They summited at 4.30pm, after 10 hours of climbing.
Burns says although the view from the top was breathtaking, it was sad to see some of the fynbos and Protea bushes damaged by the recent fire in the Western Cape mountain.
The four were sleeping in an open cave at the top of the mountain.
After having breakfast the next morning they started the decline, which was much more difficult for the two adventurers.
The tedious and tiring walk down to the stone cottage was worth it, however, when they saw David Inggs’s parents, Mark and Colleen leRoux, waiting to welcome them back with a surprise braai.
Dave couldn’t join Burns and Koos on this adventure, due to personal problems.
Trevor Long (72), Rob Beardsley (66) and Fred Ashton (72) had to withdraw previously, due to health reasons.
Burns says each climb is becoming more difficult, but they only have to conquer Mafadi, in KwaZulu-Natal, the highest of all the peaks at 3 451m, to finish what they have started.
The group of six friends decided to embark on an expedition of climbing nine peaks in nine provinces.
They are doing it to raise funds for the Northfield Methodist Church, where Burns is a member.
