Day tourism (also called a day trip or day excursion) refers to a leisure journey where visitors travel from their home base to a destination and return the same day, without an overnight stay. The typical duration ranges from a few hours to a full day (e.g., 8:00 AM – 8:00 PM).
Day tourists spend on transport, food, admission fees, and souvenirs but not lodging. They generate significant revenue for attractions, restaurants, and retail in peri-urban and rural areas. Destinations often market specifically to the day-trip market (e.g., "Visit [Town] for the Day" campaigns).
Day tourism is distinct from overnight tourism (staying ≥1 night) and same-day business travel. In UNWTO terminology, a "same-day visitor" (excursionist) is a subset of visitors who do not stay overnight.
