The sheltered shores of Glan-y-Don are
protected by the Gimblet Rock peninsula and the marina end of
the beach may have some accumulations of sea weed as a result.
However, just a little way along the beach towards Abererch the
beach is generally much cleaner, but does get a little steeper
and is not sheltered.
The majority of the beach is made up of good sand however
towards the marina there is some soft sand and mud at low tide
as the river estuary flows out right next to the beach. There is
no mud further along; the beach towards Abererch is a mixture of
sand and shingle.
