The A6131 follows the pre-bypass main road north-south through the Yorkshire town of Skipton.
The route starts at the southern end of Skipton's southern bypass, at a roundabout on the A629 at Low Snaygill. It heads north following that road's old alignment, passing through a retail park and with the Leeds & Liverpool Canal ever-present (but not generally visible) to the right.
The road squeezes through a narrow gap between the canal and the Skipton to Leeds railway line before going under a railway bridge carrying a freight line. The hospital is then passed, after which the road bears right to cross the canal and reach the town centre. The A6069 (former A59) soon comes in from the left and there's a short multiplex to a roundabout where the two roads separate again.
Now on the pre-bypass A59, we head north along the High Street to another roundabout where we meet the old line of the A65. We pass the church and the entrance to the castle and then zigzag northeastwards along a road called The Bailey, alongside the castle walls. As we head out of town the road opens out and becomes more leafy. We pass between two housing estates before bearing to the left and ending at a T-junction on the A65 northern bypass, which is dual here to aid the junction.
