Easiest approach especially for the larger units:
Leave the westbound M55 at junction 4.
At the top of the slip road take the first exit from the roundabout onto the A583.
Get into the right hand lane.
At the roundabout take the 3rd exit onto B5410 Lytham St Annes Way.
Go straight across the next roundabout.
At the next roundabout take the first exit (almost back on yourself).
In about 300m our entrance will be on your right hand side.
