17.01.21  Yr Allt (SJ 242 100) 

Yr Allt (SJ 242 100)

With the forecast set fine for the day I sauntered out on the canal towpath for a socially distanced walk with friends who I met at 9.15am.  Our plan was to visit Yr Allt, which is one of my two go-to hills during lockdown.  This and Y Golfa can easily be visited from my front door and both give good varied walking, with Yr Allt having a number of options to and from its summit. 

Heading through the wood above the Flash Leisure Centre

Today we headed from the Flash Leisure Centre to the wood that overlooks it.  From here we accessed the field above Corfield’s Farm and then it was only a short walk avoiding winter mud across another field to the farm yard, where a footpath led to another wood. 

I hadn’t used this particular footpath before and once beyond the farmyard it led through a deciduous wood, then over a large field and down leaf cluttered slopes leading to a small book.  The path led over the brook and continued toward the Gungrog Fawr Lane.  I was now on land that I had investigated during the previous lockdowns and from here continuing public footpaths led all the way to the summit of Yr Allt. 

Gaining height with Welshpool in the valley below

It was good to be out with the girls, all were quicker than me, but I was more than happy to saunter at my own pace enjoying the ever expanding view.  Nic brought Tommy the dog who was flying across the fields investigating all manner of places and having the time of his life; oh to have the energy of a little dog! 

Nearing the summit of Yr Allt

By the time we reached the summit a slight chilled breeze blew across the hill, so we de-camped on the fallen bow of a tree in the dip between the high point and the trig pillar to have a rest and bite to eat. 

After visiting the trig pillar we wandered down the connecting south-westerly ridge where two gates gave access to the top of the Rhallt Lane, from here we sauntered down the lane to the canal towpath and then home.  It proved a great way to spend three hours.
