The centre was launching its new logo and East Worthing and Shoreham MP Tim Loughton officially opened the new-look climbing wall.
Marketing adviser Debbie West explained the wall had been repainted and the climbing routes had been changed, plus a new auto belay had been added.
“Normally, people have to climb in pairs, now the more experienced climbers can go up on their own,” she explained.
Mr Loughton took to the wall himself, along with Cllr Debbie Kennard, one of the centre’s trustees.
Ms Kennard then went on to try out the Ergo, which allows people to practise paddling on dry land.
Trials of archery and mountain biking were also on offer and the centre’s new activity programme was handed out.
Manager Paul Crane said the idea of the new logo was to visually tell people what happens at the centre.
“Thousands of cars go past but the feedback was that people don’t know what we do,” he explained.
“We wanted to make it a bit more dynamic. The old logo did not really explain what we do and we wanted people to be able to see through our logo what we do.”
The logo shows climbing, mountain biking, kayaking and archery in each of the letters A0AC.
Plans for the centre, which is in Brighton Road, on the banks of the River Adur, include improving the low ropes course, by burying the tunnels so people can go underground, and the launch of a new cycle hire centre in April.
