Her and her friends from Launceston College never felt unsafe in the area, but the assault of a woman last Sunday could have made them reassess.

"When things like this happen, it's very scary," Eleanor said.

Seeing more than 100 people attend a walk on Sunday to reclaim the area was a great reassurance, however.

"To see the community come together like this, it makes me feel safer," she said.

The group gathered in the afternoon to walk along Duck Reach track in a show of defiance against anyone who believed violence against women was acceptable.

Launceston woman Kate Knights said it was empowering to know that the public was willing to stand up in the face of violence.

"We came as a group to reclaim the gorge and to show support for the female victim," she said.

"Together we can show that we're not fearful.

"I think it was why it was concerning for many was because you assume it's a safe place."

The flow of walkers along Duck Reach was greater than usual throughout Sunday - particularly given the wet conditions - as groups who could not make the afternoon walk wanted to show their support.

Walking groups also continued as normal.

Organiser Michelle O'Byrne said the group sent a clear message about their connection to the gorge: "you can't take it away from us".

"It really is about a message and saying this place is ours and we're going to take it back and we won't tolerate acts of violence," she said.

Police are yet to make an arrest in relation to the assault which occurred about 4.15pm on Sunday, March 31, on Lower Snake Gully Track near Duck Reach Power Station.

The man put the woman in headlock and covered her mouth before she was able to escape.

The attacker was described as in his early to mid-20s with blonde scruffy hair and blonde bushy eyebrows wearing a khaki shirt.
