Bankside Pier
is a stop for river services in London. It is located on the south bank of the river Thames.

Three services call at the pier: the river bus routes RB1 (between Embankment and Woolwich Arsenal) and RB2 (from here to St George Wharf Pier and Millbank Pier for the Tate Britain). The third service is the Circular Cruise Westminster which goes to Westminster via St Katherine's.
Maximum stealth needed for this cache, very popular area for muggles.

Congratulations to nchs20 on the FTF
