"If you hiked the entire Coast Path, you'd be walking for eight weeks for sure," said Harri Roberts, who has written a number of trail guides.
And the Coast Path is not exactly flat. Sure, there are parts of the trail that lead along the beaches and bays of the Irish Sea. But then it goes up mountains and hills, along cliffs and through meadows where sheep and cows graze.
There's also the weather, which cannot be underestimated.
"The wind blows in your face, regardless of what direction you're going," Roberts said.
Hikers need time to visit the many sites along the way, such as forts, castles, churches and monasteries, which sometimes are just a few steps off the path.
And there are places that look like complete foreign objects in the landscape. One of those places is Portmeirion. Visitors would think they are in an Italian fishing village turned tourist trap with its colourful houses, splendid flowers, palm trees, statues and fountains.
"Sir Bertram Clough Williams-Ellis made his dream come true here," said Meurig Jones, manager of the facilities.
Architect Williams-Ellis bought a small estate on the edge of Snowdonia in 1925 and began a mission which would last his entire life.
"In essence, he was a hoarder," says Jones. "He couldn't part with anything."
Things are not quite as eccentric in Nant Gwrtheyrn on the north coast of the Llyn peninsula.
"People have been living here for millennia. But since the granite quarry ended, so many of them have gone away," Mair Saunders said.
What remains in Nant Gwrtheyrn is the Welsh Language Centre, which she heads. It offers language courses to those who want to learn Welsh, an ancient Celtic tongue which is still the day-to-day language in many of the villages and which is undergoing a revival.
Only about 20 per cent of the Welsh can speak the ancient language.
"But the people are becoming interested in it again," sparkles Saunders.
