UCTT chairman Tim Dennis said the new 10km trail was already a hit with young families, children, and outdoor enthusiasts.
"You go out [to the track] in the weekend and it is being used by loads of people, walking and cycling," he said.
The new trail connects to the Outlet Track at Albert Town which continues alongside the Clutha River and into Wanaka.
The UCCT is already forging ahead with the next stage of its river corridor trails network and work is ready to start on a new track from Albert Town, which will follow the true right bank of the Clutha River through to Luggate.
The Albert Town-Luggate trail is scheduled to be completed by the end of the year.
A bridge across the mouth of the Cardrona River will possibly be named for the UCTT's founding chairman John Pawson, Mr Dennis said.
Mr Pawson was a respected farmer, businessman, and community figure in Wanaka, who died in a climbing accident on Mt Aspiring, last November.
Eventually, the UCCT intends to have a network of trails, which will link all of the Upper Clutha townships from Lake Hawea and Luggate, through to Albert Town and Wanaka, and out to Glendhu Bay.
A trail from Wanaka to the historic goldmining township of Cardrona, following the Cardrona River, is also being considered, he said.
An opening ceremony for the Hawea River trail will be held at the swing bridge at 1pm on Sunday, August 2.
