what countries can I travel to under the Schengen visa?

The 26 countries that fall under the Schengen agreement are as follows: Austria, Belgium, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Italy, Latvia, Liechtenstein, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, and Switzerland.

The Schengen visa allows you to travel freely within the Schengen area, for a maximum period of 90 days in a 6 month time frame.    The countries in the Schengen area should not be confused with the European Union (EU).  It does not cover 2 EU countries (United Kingdom and Ireland) and includes 3 non-EU countries (Norway, Iceland and Switzerland).
