|Route outline (key)|
The B4403 runs along the southern side of Bala Lake in North Wales.
The road starts on the A494 on the edge of the village of Llanuwchllyn and to begin with heads southeastwards through the village. It quickly crosses the River Dee and soon bends sharply left by a roadside car park to cross the River Twrch and head northeastwards.
The road now starts running parallel to the narrow-gauge Bala Lake Railway. It reaches Bala Lake itself after about a mile and follows both for virtually all its remaining length, although owing to vegetation they cannot always be seen.
The first place of any size at all alongside the lake is Llangower, which has a church, stream crossing and campsite. Eventually the B4403 crosses the railway line to reach the hamlet of Pont Mwngwl-y-llyn where it ends on the B4391. There is an old bridge to the left (over what was the River Dee), now pedestrianised, which is the original route of the B4391 but now the B4403 continues ahead for a short distance before ending at a T-junction. Bala itself is a short distance to the left.
