San Juan, Puerto Rico For Less Than $150 Round-Trip

October is one of the least popular times to visit San Juan. Puerto Rico’s vibrant capital city offers a lot for visitors in October.

The city is known for its cuisine, so a food tour should be at the top of the list. Puerto Rico is also known for its rum. Visitors can take tours at various distilleries to learn the history of rum-making before learning how to prepare it in cocktails.
