Large-scale industry ended with its closure in 1960, after which began the clean up: many of the buildings were demolished, rubble was either discarded beside the roads or/and buried, and the majority of the rail tracks were removed and reused as fence and gate posts, which can still be seen around the village.

The rare properties of the granite within the quarry made it the perfect material to produce curling stones for the winter Olympics.

[1] Tre'r Ceiri, the second highest of the hills, has one of the best examples of a Stone Age or Neolithic settlement in Europe on its summit.

Views from the summits, on a clear day, extend to Ireland, the whole of Cardigan Bay, Anglesey, Snowdonia, and the northern mountains of England.

There are two retail outlets in Trefor: a village shop which opens between 7.00 am and 7.00 pm Monday to Friday with shorter hours at the weekend, and a post office.

It is possible to go on a pushchair-friendly circular walk, starting at the play area, down to the beach, across the headland and back into the village again.

Since 2015 a cycle club has been established in the village and surrounding area called Clwb Beicio'r Eifl.
