No, a regular Netherlands Schengen Visa is generally not valid for travel to the Dutch Caribbean islands such as Aruba or Curaçao. These islands are part of the Kingdom of the Netherlands but follow different visa rules. If you plan to visit these Caribbean territories, you may need to apply for a separate Dutch Caribbean Visa. It is important to check the exact visa requirements before applying. Do not assume that a Schengen visa automatically allows entry to these islands.
