Studying park's history on foot.
The walk is being organised this Saturday (September 8) by the park's Friends group.
Participants will get the chance to see the Victorian park's main features and learn about its fascinating history.
The free walk has been organised as part of the national Heritage Open Days.
The annual event celebrates the town's history and heritage with free visits and activities.
The circular walk, which lasts up to 90 minutes, starts from the Trinity Street gates at 10.30am and then again at 2pm.
It finishes at the park's restored conservatory, where there will be a Friends stall from 11am until 4pm.
The stall will feature old photographs and maps of the park on display.
There will also be information about the group and park activities.
Visitors will be able to pick up a new leaflet to accompany the heritage information boards in the park.
