Military history buffs will appreciate the Scapa Flow Visitor Centre, which displays military vehicles and guns from both world wars. You'll also find equipment salvaged from the German boats scuttled off the coast. In the plain but poignant graveyard here, British and German personnel both rest in peace. If you want to take your car over to Hoy, book well in advance with Orkney Ferries, as this is a popular route. The visitor center is a short walk from the ferry terminal
on the island of Hoy.
