The Church of the Nativity in Bethlehem is a profoundly sacred site marking the traditional birthplace of Jesus, offering free entry to all visitors. While generally accessible, be aware that descending into the Grotto of the Nativity involves steps and can be challenging for those with mobility concerns. Visitors can explore independently, but a local guide is highly recommended to provide invaluable historical and religious context, particularly regarding the different denominational sections. The church is open year-round, but expect extremely large crowds and potentially altered access during major Christian holidays like Christmas and Easter; early morning or late afternoon visits are often best to avoid peak times. Allow 1-2 hours for your visit, which can extend due to significant queues, especially for the Grotto. Modest dress (covered shoulders and knees) is required, and be prepared for security checks upon entering Bethlehem.
