There have been growing numbers of visitors to the Exclusion Zone each year, and there are now daily trips from Kyiv offered by multiple companies. In addition, multiple-day excursions can be easily arranged with Ukrainian tour operators. Most overnight tourists stay in a hotel within the town of Chernobyl, which is located within the Exclusion Zone. According to an exclusion area tour guide, as of 2017, there are approximately 50 licensed exclusion area tour guides in total working for approximately nine companies. Visitors must present their passports when entering the Exclusion Zone, and are screened for radiation when exiting both at the 10 km checkpoint and at the 30 km checkpoint.
