The popular walking track to the rocky beach, which starts above the St Clair Hot Salt Water Pool, was damaged when heavy rain in July 2017 caused several slips and undermined the walkway.
Repairs began about six months ago and included earthworks above the track to clear slip debris, the construction of retaining walls and new safety fences, work on slip faces to stabilise the bank above the track and digging drainage channels.
Dunedin City Council parks and recreation group manager Robert West said the work cost $340,000.
"Planting and re-vegetation of the slopes above the track will be completed in spring."
The council was also erecting hazard signs, warning of rockfalls, landslips and the risk of falls, and a low barrier would be constructed at the end of the track, he said.
St Kilda woman Mary Laws was enjoying an amble on the track yesterday and said she wanted to convey her thanks to the council for the quality of its work.
The 83-year-old had many happy memories of walking on the track and was thrilled it was finally open.
"All of us old ladies were getting fat."
