Traeth Bychan, Marian-Glas, Anglesey, North Wales

Traeth Bychan, as its name suggests (Traeth = Beach, Bychan = Small), is a beautiful bijou beach. This secluded, sheltered, sandy little bay is a haven for watersports enthusiasts, especially sailors, as well as walkers and families looking for some old-fashioned seaside fun.

Traeth Bychan beach faces eastwards and therefore offers shelter from the worst of Anglesey’s prevailing southwesterly winds. On sunny summer days it’s bustling with boats and nautical banter. But visit on a clear winter's morning, and you might not see a soul.


Traeth Bychan has something for everyone: a gorgeous location, breathtaking views, watersports galore, fabulous fishing, rock-pooling, picnicking and wonderful walks in all directions! With plenty of room for everyone, and for every type of beach activity, it’s well worth a visit.

Facing east and backed by cliffs it provides a relatively safe and sheltered bay for bathing.


Especially for beginners.


Kayak hire available close by.


Yes - the entire length of this coast, including Traeth Bychan, offers some excellent fishing opportunities. Not known for its huge catches, but expect to land a place or two! There’s a small stream running across the beach to the right - apparently, this is good for bass and flounders, especially on flood tides. If you don’t have a boat of your own you can hire one locally. Fishing off-shore gives you more scope, as well as the chance to look back at the beautiful shore. In mackerel season you might see a dolphin or porpoise out and about too! Head north or south along the Anglesey Coastal Path, and you’ll find some excellent fishing marks on the ledges along the way!
