The B4411 is a short rural B-road in western Caernarfonshire.
The road starts on the A487 (former B4410) at Glan-Dwyfach and heads south, initially parallel to the River Dwyfach. After a mile or so the river heads off to the west whilst the B4411 continues south. The road thus climbs out of the valley and goes through Rhoslan, after which it bends to the east and crosses the valley of the Dwyfor.
A few hundred yards later the road turns southerly once more. It enters the town of Criccieth and descends down to the coast, ending at a crossroads on the A497. The unclassified road opposite crosses the railway line to reach the seafront.
