|Route outline (key)|
The B4413 is a rural B-road in western Caernarfonshire.
It starts almost at the tip of the Lleyn Peninsula, in the coastal village of Aberdaron. On the southern edge of the bridge over the River Daron the road bends sharply to avoid going into the sea; the B4413 starts here. It heads north across the river and climbs out of the village. It continues northeastwards, roughly parallel to the River Daron but preferring to stay out of the valley.
After going through Rhoshirwaun the road reaches Pen-y-Groeslon where the B4417, the road along the northern side of the Lleyn Peninsula, turns off to the left. The B4413 continues ahead to Sarn Mellteyrn where a series of sharp bends turn the road southeasterly. After a couple of miles it reaches Botwnnog and then Bodlondeb; the B4415 leaves here. As can be seen at the signpost at the junction, this road and the B4413 both lead to Pwllheli (although neither actually gets there).
Continuing vaguely eastwards the B4413 goes through the scattered village of Mynytho before ending in Llanbedrog, about a mile later. The road terminates on a T-junction on the A499.
