Second home tourism in Spanish Mediterranean coastal areas has created a great real estate market demands in which local communities and authorities are both involved. Based on tourist area life cycle theory (TALC) current conditions of some tourists Mediterranean coastal areas in Spain falling to a degree of degradation or even stagnation among their practical life cycle, which demonstrated as last phases of TALC theory. Many second home projects were built within Spanish costal zones during a rapid growth and the boob construction period in Spain, started from 1970s.
