I am starting a new job at the beginning of July and have managed to secure 4 nights stay at a rental in Llandeilo, on the western edge of the Brecon Beacons in Wales before I start, at the end of June.

It is just the wife and I. We are not hikers or ramblers but do appreciate outdoor beauty with mountains and sea.

For those in the know, can you recommend:
1. Places to visit eg landmarks or areas of beauty etc
2. Places for lunch
3. Places for dinner

Thanks
