The term 'isolated area' can be described as an 'ENCLAVE', which is a seven-letter word. An ENCLAVE is a territory, area, or region that is completely surrounded by the territory of another state. It is usually politically distinct from the surrounding state and is often economically and culturally different. Enclaves are often created to protect minority populations or to provide a safe haven for a particular group. Examples of enclaves include Vatican City, which is surrounded by Italy, and Kaliningrad, which is surrounded by Lithuania and Poland.
