I had forgotten about another flat walk I do sometimes. It's not strenuous but is easy and enjoyable.
Starting from Penrhyn Beach East go up the steps and turn right and follow the path to Angel Bay. With a bit of luck you might see seals along the way (the most I've seen was 27) or even the Peregrine Falcons that live by the old quarry.
Retrace your walk and continue ahead past the steps that you came up and continue along the footpath until you come to a private road. Walk along the road and you come out at the bottom of Penrhyn Hill.
Cross the road carefully and you can then either visit Batty's Nursery or look at Penrhyn Old Hall and the old Chapel or do as I do and go around the corner and have a nice Cappuccino and cake at Home from Home Cooking.
To return to the start of your walk you can either retrace your steps along the private road or go past the Co-op and walk along the pavement to the start.
