Setting off from Barmouth Derek Brockway takes in the famous Panorama Walk
In the first in a new series of Weatherman Walking (Wednesday, 27 January, BBC One Wales) Derek Brockway walks two of the most popular - and spectacular - routes in Wales.
The first cherry-picks some of the best views in and around Barmouth and the second travels over the famous ridge of Pen-y-fan, the highest mountain in southern Britain and a training ground for the SAS.
Derek meets Snowdonia National Park warden Gethin Corps and sets off with him from the centre of
They ascend high above the town before taking in the former Victorian attraction of the Panorama Walk.
After admiring the stunning views of the Mawddach estuary he then visits the old megalithic remains of Arthur's Stones and follows the old main road to Barmouth, favoured by the drovers but now abandoned to hill walkers.
He continues through Welsh gold mining country before crossing the river again at Penmaenpool and finishing the walk at the former railway station closed during the 1960s as part of the Beeching cuts.
For his second walk he heads south to one of the most popular walking destinations in Wales - Pen-y-fan. Shunning the popular route to the top, from the Storey Arms car park by the side of the A470, Derek has a stab at the Horseshoe Route, kicking off at the bottom of the Roman Road running alongside the Upper Neuadd reservoir.
Before climbing the three peaks of the Pen-y-fan range, Derek takes a detour to scale Ffan-y-Big, testing his nerves on the infamous stone outcrop known as the "diving board" before heading back down and scaling Cribben.
Low cloud and mist hamper his views, but by the time he reaches Pen-y-fan, the clouds lift to reveal some spectacular views.
At Corn Ddu the last of the three peaks, he learns about the story of Tommy Jones, a small child lost on the mountains more than 100 years ago, before heading across Craig Gwaun Taff which gives visitors a stunning view of this iconic mountain range.
