FLC TAXIES THROUGH DESIGNATED PARKING AREA AT BWI.

Narrative

WHILE TAXIING IN TO GATE AT BWI; I CLRED RWY 10 BY TURNING L ONTO RWY 4; THEN L ON TXWY P. FO CONTACTED GND CTL; AND WE WERE TOLD TO 'TAXI TO THE GATE VIA TXWY A.' I TAXIED VIA WHAT I THOUGHT WAS A PROPER RTE TO THE GATE. NO ACFT WERE ON GATE XA THROUGH XO. I HAD THE TAXI CHART OUT AND WAS REFERRING TO IT. I THEN WENT AROUND A BUILDING TO THE R; AND TAXIED BTWN CONCOURSE AND THE BUILDING. AS I TAXIED; IT SEEMED A LITTLE UNUSUAL; SO I LOOKED FOR SIGNAGE INDICATING 'NO TAXI' OR THE LIKE AND SAW NONE. I PROCEEDED TO THE GATE; AND AFTER PARKING I LOOKED CAREFULLY AT THE TAXI CHART AND ONLY THEN DISCOVERED A NOTE WITH A LONG LEADER LINE POINTING TO THE AREA I HAD JUST TAXIED THROUGH. IT SAID THE AREA WAS FOR GATE PARKING ONLY. I HAVE NOW HIGHLIGHTED THE NOTE. AT NO TIME WERE PERSONNEL OR EQUIP IN DANGER. I FEEL THE NOTE ON THE CHART WAS EASY TO MISS EVEN WHEN LOOKING AT THE CHART CAREFULLY. OBVIOUSLY I WILL BE MORE DILIGENT IN THE FUTURE. I SPOKE TO THE CTLR IN THE TWR AFTER THE FLT; AND HE SAID THERE HAD BEEN NO CONFLICT AND TO JUST BE CAREFUL IN THE FUTURE.
