From the North West, take the M56 to the A55. This goes most of the way to Bangor. Turn left off Beach Road to the Swimming Pool which is sign-posted.
From the Midlands, East and South, take the M54 to Telford, the A5 to Shrewsbury, the A483 to Wrexham and Chester and finally the A55 to Bangor. Turn left off Beach Road to the Swimming Pool which is sign-posted. Don't be tempted to use the A5 all the way to Bangor from the M54 as it is very slow and winding.
By Raillink, take all routes from Crewe/Chester to Bangor.
