Top Things to Do
Sunrise Stroll Through Old San Juan's Cobblestones
Wake before the city truly stirs and wander through the pastel-hued streets of Old San Juan. The soft morning light illuminates the colonial architecture, casting long shadows and offering a peaceful, almost magical atmosphere before the day's bustle begins. Look for the intricate ironwork balconies and listen for the distant sounds of roosters.
El Yunque National Forest: Beyond the Main Trails
Venture beyond the popular observation towers and seek out lesser-trodden paths in El Yunque, the only tropical rainforest in the U.S. National Forest System. Hike to hidden waterfalls like Juan Diego Creek for a refreshing dip, or explore the Yokahú Tower for stunning, less-crowded vistas. Listen for the unique call of the coqui frog, especially after a rain shower.
A Taste of Mofongo at a Local 'Fonda'
Skip the tourist traps and seek out a 'fonda' (a small, casual eatery) for an authentic mofongo experience. This classic Puerto Rican dish of mashed plantains, often filled with savory meats or seafood, is best enjoyed when prepared with generations of tradition. Ask locals for their favorite neighborhood spot for the most flavorful and satisfying rendition.
Kayaking the Bioluminescent Bay of Fajardo
Embark on a nighttime kayaking adventure in the Laguna Grande bioluminescent bay. As your paddle disturbs the water, millions of microscopic organisms ignite, creating an ethereal, glowing trail. The darker the night, the more spectacular the display, so aim for a new moon phase for the ultimate celestial and aquatic light show.

Essential Travel Tips
Don't leave San Juan without trying a 'pincho' from a street vendor, especially in the Condado or Ocean Park areas. These skewers of marinated meat or seafood are a delicious and cheap way to sample local flavors, often costing just a few dollars.
While taxis and ride-sharing apps like Uber are available, consider using the public bus system (AMA) for longer distances within San Juan, like traveling from Old San Juan to Isla Verde. It's incredibly affordable, usually just $0.75 per ride, and a great way to see more of the city like a local.
Carry some cash for smaller establishments and street vendors, as not all accept credit cards, especially outside the main tourist zones. ATMs are readily available, but having smaller bills on hand will make transactions smoother, particularly for tips or quick purchases.
Embrace the 'island time' mentality, especially when dining out or waiting for services. Things might move at a more relaxed pace, so be patient and enjoy the moment – it's part of the charm of Puerto Rico!
Pack light, breathable clothing and plenty of sunscreen, as San Juan is warm and humid year-round. Don't forget insect repellent, especially for evenings near the coast or if you plan to explore any nature reserves, as mosquitoes can be prevalent.
Be aware of your surroundings, especially in crowded areas like Old San Juan or busy beaches, and avoid displaying expensive jewelry or electronics. While generally safe, petty theft can occur, so keep your valuables secure and be mindful of your personal belongings.
💡 Travel Tip: If you're planning your trip, it's worth checking flight prices on Trip.com before you decide.

Frequently Asked Questions
When's the absolute best time to visit San Juan if I want to avoid the biggest crowds but still enjoy great weather?
For that sweet spot between pleasant weather and fewer crowds, aim for the shoulder seasons: late April to early June, or September through November.

I'm planning to explore Old San Juan on foot. What's one thing I absolutely shouldn't miss that most tourists overlook?

What's the deal with transportation? Is it easy to get around San Juan without a rental car?
Absolutely! For exploring Old San Juan and Condado, you're better off walking or using ride-sharing services like Uber, which are plentiful and affordable.

While mofongo is a must-try, don't shy away from 'pinchos' from street vendors, especially in areas like Santurce during evening hours – they're delicious skewers of grilled meat or seafood.
