Antigua's rum distilleries are open year-round, so you can take a tour whenever you visit the island. However, the best time of year to take an Antiguan rum tour may depend on your personal preferences and travel plans. The peak tourist season in Antigua runs from December to April, when the weather is dry and sunny, and there are many cultural events and festivals happening.
This may be a great time to take a rum tour if you're looking for a lively atmosphere and lots of activities. Alternatively, if you prefer quieter travel, the off-season months of May to November may be a better time to visit, as the island is less crowded, and you may find better deals on tours and accommodations.
