Start your trip by visiting the historic city center of San Juan, Old San Juan. This UNESCO World Heritage Site is home to colorful colonial-style buildings and forts, such as Castillo San Felipe del Morro and Castillo de San Cristobal. Stroll down the cobblestone streets, admire the colorful architecture, and indulge in some traditional Puerto Rican cuisine at one of the many restaurants and cafes.
Explore the lush tropical rainforest of El Yunque National Forest. Hike through the trails and admire the various waterfalls and streams throughout the forest. Here, you may also spot various species of birds, coquis, and other wildlife native to Puerto Rico. Don't forget to bring your swimwear, as there are several natural pools and swimming holes to take a dip in.
Experience the natural wonder of bioluminescent bays by kayaking through one of the three bio bays in Puerto Rico. As you paddle through the water, you'll see the bioluminescent microorganisms light up the water, creating a magical glow beneath the kayak. While paddling, you might also see some marine life, like stingrays and jellyfish, in the water.
Finish your trip by relaxing on the beautiful beaches of Culebra Island, one of the top-rated beaches in the world. Snorkel in the pristine waters, explore the coral reefs and colorful fish, and soak up the sun on the white sandy beaches. Take a hike up to Culebrita Lighthouse for a spectacular view of the island and its surroundings.
Renting a car is the easiest way to get around Puerto Rico. A car rental for four days can cost around $120, with gas costing around $2.50 per gallon. Taxis and buses are also available, but may not be as convenient.
If you have more time, consider exploring other attractions in Puerto Rico, such as the Arecibo Observatory or Flamenco Beach. If you have less time, consider skipping the bioluminescent bay kayaking or Culebra Island.
Luis Muñoz Marín International Airport (SJU) is the main airport serving Puerto Rico. It is located in San Juan and is about a 15-minute drive from Old San Juan.
