The three are part of the 18 communities in Wales chosen to be part of the £1.2m project and will receive support, tools, and training to help improve local paths and nature.
Mid Wales Paths to Wellbeing Project Officer Kate Blair said: “Each one of the communities we’ll be working in has their own unique characteristics and history. Llechryd has contended with the swell of the River Teifi for centuries but boasts some truly stunning walks along the river.
“Penparcau is home to one of the largest and most important hillforts in Wales, Pen Dinas.
“Towering above the nearby student town of Aberystwyth, Pen Dinas overlooks the sea from a ridge of high ground between the rivers Rheidol and Ystwyth.
“The area is rich in nature with volunteers recently having engaged in a five-year species survey.
“Rhayader is believed to be the oldest market town in mid Wales due to the location being a natural stopping place for travellers. There are some incredible places to walk in the area and we hope that Paths to Wellbeing can play an important role is maintaining and improving local access.
“I’m excited to help volunteers shout about the rich history of the three communities.
“What really stood out was the passion of each one to improve paths and nature in their local area. I’m really looking forward to working with them to improve and establish new routes.”
