Soest is a medium-sized city in the Dutch province of Utrecht. It's known as a major base for the Dutch army, which uses large parts of the forests and heathlands of the surrounding Soesterduinen and Soesterberg as training grounds. For visitors, those same natural surroundings make for good hiking and biking opportunities, and there's an interesting army museum to visit. The National Military Museum is situated on the former air base at Soesterberg. It combines the collections of the former Military Aviation Museum in Soesterberg and the Army Museum in Delft.
