What are some special attractions? what's your best bet?

In the few hours I spent in Puerto Rico many years ago, I thoroughly enjoyed through the tropical rain forest. I also had my first taste of freshly picked pineapple - much better than the taste of pineapples shipped to our supermarkets.

My favorite travel guide has information about the main attractions.

Some special attractions in Puerto Rico include:

1. El Yunque National Forest: This is the only tropical rainforest in the United States National Forest System. It offers beautiful hiking trails, stunning waterfalls, and diverse flora and fauna.

2. Old San Juan: Explore the historic district of San Juan, with its colorful cobblestone streets, charming colonial architecture, and famous landmarks like El Morro and San Juan Cathedral.

3. Bioluminescent Bay: Visit one of Puerto Rico's bioluminescent bays, such as Mosquito Bay on Vieques Island or Laguna Grande in Fajardo. These natural wonders light up at night due to the presence of bioluminescent organisms in the water.

4. Culebra and Vieques Islands: These islands are known for their pristine beaches, crystal-clear waters, and vibrant marine life. Flamenco Beach in Culebra is often ranked among the world's best beaches.

5. La Fortaleza: Take a tour of the historic governor's mansion in San Juan, which is also the oldest executive mansion in continuous use in the Americas.

As for my best bet, it would be difficult to pick just one as it depends on your interests and preferences. However, exploring the beautiful El Yunque National Forest is a popular choice for nature lovers and hikers. For history enthusiasts, visiting Old San Juan and its iconic landmarks is a must. If you enjoy beach activities and crystal-clear waters, a visit to Culebra or Vieques Islands would be a great choice.
