On our drive home we stopped for a walk at Llyn Trawsfynydd.

We walked around some of the reservouir and spotted some different fungi. We watched a man using a machine, a bit like a hoover to suck and pump all the water out of the boats which are for hire.

The Trawsfynydd nuclear power station opened in 1965 and was decommissioned in 1991.

The power station is a big grey building with no windows.
