El Morro: Check out the historic sites of Old San Juan, including on of its most famous forts, whose original parts were completed in 1539 (and which successfully deterred would-be colonial powers from capturing the island). Tours are from 11 a.m. to 3 p.m., with an entry fee for adults, though the fee also covers the cost of San Cristobal Fort.
San Cristobal Fort: Also in Old San Juan is a second fort, which was built in 1771. On weekends, the grounds of both forts are thick with locals flying kites. (Tours from 10 a.m. to 2 p.m.)
Museo Pablo Casals: Fans of the Spanish cellist Pablo Casals should check out the museum dedicated to the musician, where the Spanish master's collection includes manuscripts, photographs and a library of video tapes of Festival Casals concerts (played on request). (Plaza San Jose, Tuesday through Saturday from 9:30 a.m. to 4:45 p.m.)
Bacardi Rum Factory: This is commonly offered as a ship-sponsored tour, but it's easy to go on your own, too; take the ferry (which leaves from Pier 2, right next to the cruise ship dock, every half hour and costs $1, roundtrip, for the six-minute ride) to Catano, and then catch a bus or ferry for the 10-minute ride to the factory. (Don't walk -- it's long and hot.) The factory itself is lovely. There are gorgeously landscaped grounds (lots of hibiscus), an open-air pavilion for Bacardi-influenced drinks, a gift shop and a tour that can lead into your very own mixology course if you upgrade your ticket.
El Yunque: It's hard to visit San Juan and not be drawn to El Yunque, the only rainforest designated as a U.S. National Forest. Located about an hour south of San Juan, you'll see numerous waterfalls, ferns and wildflowers along the marked trails. Because it's a rainforest, it will probably, well, rain during your visit -- so pack a slicker.
The Museo de Arte de Puerto Rico in Santurce: This off-the-beaten-path museum exhibits elegant Puerto Rican art, along with visiting themed shows.(Just south of Condado, 299 De Diego Avenue, open from 10 a.m. Wednesday through Saturday and 11 a.m. on Sunday; closed Monday and Tuesday). Art-lovers who want to stick closer to town can visit the Museo de Arte Contemporaneo de Puerto Rico, which houses some 700 post-1940s works from artists of Puerto Rico, the Caribbean and Latin America. (229 de Diego Avenue)
The Beach: While Old San Juan doesn't really boast any of its own, the beaches in the nearby areas of Condado and Isla Verde stretch along high-rise hotels and are a 5- to 10-minute taxi ride (longer during rush hour) from the cruise pier.
For Golfers: Bahia Beach is a hidden treasure; a car rental is required to get to this out-of-the-way, 18-hole public course that sits at the base of El Yunque and fronts the sea with a gorgeous beach, framed by palms and palmettos. Being totally public, it's also open to non-golf-playing visitors (though the club does request that you politely ask permission). Golf clubs are available for rent.
There are two port facilities in San Juan -- one is a 10-minute ride, close to the airport, called the Pan American terminal, while the main cruise terminal (Piers 1, 3 and 4) is just a short walk from downtown Old San Juan. A 10- to 15-minute walk will get you to most restaurants and attractions (about 25 minutes to El Morro). A free trolley is also available from the port to explore the sights. At the terminal itself, local vendors usually set up stands selling knick-knacks as souvenirs. Otherwise, the immediate port area can be very commercial with a mall, ice cream shops and chain stores like Domino's and Senor Frog's. For a more authentic meal, venture into town.
On Foot: It's walking distance into compact, yet fascinating, Old San Juan. Streets are uneven (constructed of blue cobblestones, cast from furnace slag), and hills are steep, so wear comfortable shoes.
Taxis: They're available at the dock. You can also hail mini-buses (called "omnibuses"), which shuttle along main routes; to hail one, respond with a wave when the driver toots his horn.
Trolleys: There's a free trolley that will take you around Old San Juan and to the forts. You can pick it up across from the information booth, between cruise piers three and four.
Renting a Car: There is a Hertz Rent-a-Car in Old San Juan on Calle Brumbaugh, and other agencies in Condado (about 5 miles away) or closer to the airport -- but due to a severe lack of parking around Old San Juan, we don't recommend a car if you're staying in town. Only consider renting a car if you have time on either side of your cruise to explore further into Puerto Rico.
Rideshare: Uber is available in San Juan, but not Lyft. It might be easy to find a ride downtown, but be cautious of traveling far outside of the city -- it might be trickier to find a ride back.
Best Beach for a Half-Day Visit: The beaches that run in front of Isla Verde's luxury hotels (about a 20-minute cab ride) are the best for short visits; ask the cabbie to drop you off at the Ritz-Carlton or the El San Juan.
Best Beach for the Dedicated Beach Bum: Luquillo Beach (near El Yunque) is a real locals' haunt; there, you'll find long stretches of sand, water sports equipment rentals and a great line of food stands, offering classic Puerto Rican beach food.
Best Secluded Beach: The aforementioned Bahia Beach is great for those looking for some peace and quiet. Pena, located in front of El Capitolio (the capitol building), is a local gem in more ways than one: it's super close to the city and offers a delightful array of seaglass.
Food and Drink
Bagua is a local favorite in Condado, offering a creative menu of Puerto Rican dishes such as plantain-crusted mahi mahi. Past diners rave about the sangria and the ceviche.
A good spot for a light, healthy lunch or dinner is St. Germain Bistro & Cafe, where you can choose from a selection of sandwiches and salads -- like the Arabian (pesto chicken, grape tomato and hummus on pita bread) or the Ginny (mixed greens, shrimp, carrot, tomato and parmesan cheese with a ginger vinaigrette). Also on the menu are quiche and crepes.
The Parrot Club (363 Fortaleza) is the restaurant that inspired San Juan's gourmet revolution, and while it's a bit more passe these days, it's one of the few in the trendy SoFo (south of Fortaleza restaurant district) to open for lunch. It's known for its Nuevo Latino cuisine.
Because many ships spend evenings in San Juan and don't depart until late-night, cruisers should also consider dinner options. Head to the aforementioned SoFo, where the hip restaurants of the moment include Marmalade (317 Fortaleza), which offers a U.S.-inspired menu. (For a great thirst quencher, try the signature drink at the hip Marmalade restaurant; the M317 martini consists of Cointreau jelly, limoncello, triple sec, Campari and grapefruit espuma -- a whipped cream without eggs.)
Aguaviva (364 Fortaleza Street) is another trendy place; it serves seafood. (Note the whimsical, octopus-like chandeliers.)
Don't miss out on a pina colada from Barrachina (104 Calle Fortaleza), its supposed birthplace. For something a bit more modern, order a house favorite, the lavender mule, at trendy La Factoria on Calle San Sebastian.
Medalla Light is the local beer, and while Bacardi is the better-known rum produced in Puerto Rico, the locals prefer Don Q -- an equally (if not more) venerable brand.
