San Juan — the capital of Puerto Rico — is the gateway to the Southern Caribbean and an island destination worth its own visit.

See the best Puerto Rico has to offer — and kickoff a Caribbean cruise vacation — when you stop in San Juan during, before or after your Princess cruise. To help you get started planning your perfect itinerary, these are 25 of the must-do activities in San Juan that will have you counting down the days until you’re soaking up the sun in this island paradise.

Why visit San Juan, Puerto Rico?

San Juan is the oldest U.S. capital and one of the oldest U.S. cities — with roots dating back over 500 years. While the native Taínos people have lived in Puerto Rico for centuries before the Spanish came, San Juan itself got its start from the Spanianards. The Spanish explorer Ponce de Leon founded the original Puerto Rican settlement Caparra in 1508, which soon moved to the San Juan area. Because of this combination of cultures, San Juan is a melting pot of Spanish colonial heritage and Caribbean influences.

It’s also a fantastic vacation spot because of its unique blend of history, rainforest adventures, Caribbean beaches and port city cuisine. If you’re looking to hike up lush green hills for views of turquoise seas, you can do that here. Looking to spend the day exploring buildings from the 1500s and the nights dancing? San Juan is the perfect place. A day at the beach? Snorkeling to coral reefs? Food tours? Check, check and check! Whether you’re looking for relaxation, adventure or a culinary experience, San Juan has it all.

Don’t miss the Ballaja Barracks that acted as housing for regiments in the nineteenth century and now acts as the Museum of the Americas where you can wander through four permanent exhibits on Caribbean history, African heritage and Spanish colonialism.
