Mitre Peak is difficult to reach and as a result ascent attempts are relatively infrequent. The first known attempt of the peak was in 1883 by Invercargill artist Samuel Mereton, and Donald Sutherland. The pair took a boat to Sinbad Bay on 6 February and camped at the head of the valley. The next day, with little equipment, no coats and one biscuit each they climbed to the crest of the Mitre Range, from where they could see Mitre Peak over 3 km away to the east. With it being too late in the day to descend, they slept where they were overnight, before the next day abandoning the attempt to avoid an approaching storm. After a difficult descent they waited for two more days in bad weather at the head of Sinbad Gully before rowing back across Milford Sound to the hotel operated by Sunderland's wife.
