Dear Stakeholders,
With the announcement of the reopening of the international airport set for October 1st, the National Oversight Committee (NOC) has expanded the range of properties that will be eligible to reopen during Phase 3, within the Tourism Safe Corridor. Phase 3 is now therefore open to accommodations which offer the following on their premises:
Full service restaurant and bar; OR
Fully furnished kitchen with the ability to offer grocery delivery services for guests; OR
Establish an agreement with a licensed restaurant or catering service to provide daily meals for guests
Additionally, properties must also have a pool and/or beach front access, on-site guest entertainment/activities (games, gym, spa), and the ability to provide guided tours for guests.
During this "safe corridor' phase, properties will still be required to manage and control the movements of their guests as guests will not be permitted to explore the country on their own. For more information on applying to open within the Tourism Safe Corridor, please click here.
Yours in Tourism,
Belize Tourism Board
