Saturday

4. ­Shop Local, 11 a.m.

Grab a coffee and pastry at one of the city’s myriad confeitarias and save room for an early lunch. Check out the excellent local design at Feeting Room, a chic concept store selling clothes and accessories, including beautiful leather goods by the Porto brand Maria Maleta. Up the stairs at A Vida Portuguesa you’ll find colorful, nostalgic Portuguese products, from notebooks to cans of sardines, all with retro-style packaging intact. Half living room, half shop, Mercado 48 has the kind of souvenirs that you’ll be proud to show off at home, like the modern cork-and-ceramic teapots and mugs, glazed in a variety of colors, that give a nod to Portugal’s history of cork production. The Centro Comercial Bombarda doesn’t open until noon, but this collection of small shops and restaurants on the gallery-thronged Rua da Bombarda is heaven for shoppers looking for boutiques crammed with goods from homegrown designers.

5. ­Champagne Tastes, 1:30 p.m.

If dinner at the Michelin-starred Pedro Lemos restaurant will break the bank, it’s still possible to try the eponymous chef’s food. Along with his wife, Joana Espinheira, Mr. Lemos opened Stash, a sandwich shop, in 2014. Break here for a sandwich of black Iberian pork cooked for 12 hours and slicked with basil mayo, or a barbecued chicken sandwich with homemade pickles or French fries garnished with rosemary, and throw in a glass of wine for 2 euros. Lunch for two, around 18 euros.

6. ­Cathedrals and Cloisters, 3 p.m.

A Porto landmark, the twin-towered cathedral, Sé do Porto (free admission), is a gorgeous amalgamation of architectural details from multiple centuries, beginning in the 12th. The result is a historic building that’s Instagram-worthy inside and out. Be sure to explore the hauntingly atmospheric 14th-century Gothic cloister (3 euros), with its exquisite stonework and decorative azulejos. The plaza on which the cathedral sits leads to a perfect view over the sea of picturesque red-roofed houses that slope down to the river.

7. ­Photo Break, 4 p.m.

Housed in a former jail, the Centro Português de Fotografia (free) has an unusual setting as well as impressive temporary photography exhibitions. The building dates to the 18th century and held prisoners until the Carnation Revolution in 1974; grills still cover the windows. On the third floor is a hugely impressive collection of cameras from every decade, including some fabulous “espionage” cameras from the ’60s, ’70s and ’80s that are disguised as rolls of sweets, cans of Pepsi and packets of Marlboros.

8. ­­Clerics’ Tower, 5:30 p.m.

Unbeatable panoramic views of Porto’s churches and rooftops, its historic port warehouses, the curve of the Douro River and the seagulls sweeping over the waterfront Ribeira neighborhood may be had from the belfry of the Torre de Clérigos (admission 3 euros), 225 steps up a narrow spiral staircase. The rooms off the stairs are home to an exhibit documenting the history of the 18th-century tower’s inhabitants and architects; the adjacent church (included in the admission fee) is also worth a look.

9. ­­­Tapas, Portuguese Style, 7:30 p.m.

A delightful trend that’s ramped up in Porto is petiscos, the Portuguese version of tapas. Instead of a sit-down dinner, try out a few of the newest places. On Rua dos Caldeireiros, a handful of restaurants have recently appeared, of which Caldeireiros is the standout. Stop here for the alheira de caça, a sausage made with white meats like rabbit and chicken, and served with garlicky spinach. Or try the pork loin sandwich, topped with melted local cheese (wine and small plates for two, around 25 euros). One street over, Trasca offers treats like tiny roasted green chiles (3.50 euros) with a glass of vinho verde (3.50 euros). The casual ambience and plentiful outdoor seating at Porta’O Lado are attractive, but dishes like the mini version of the francesinha, a local sandwich of sausage, steak, cheese, egg and tomato-beer sauce, are the real draw. Pair with wine from the Douro Valley (wine and small plates for two, around 20 euros).

10. ­­­Late Night Tipple, 11 p.m.

Porto’s best bars are also its most relaxed. Garrafeira AMS is a dimly lit wine shop with a few simple tables and a menu of carefully selected Portuguese wines sold by the glass (you can also pull a bottle from the shelves and drink it there). Walk down the block to the most effortlessly cool bar in town. It’s smoky and crowded inside Candelabro, but you won’t find relief on the sidewalk, where patrons congregate, bottles of Super Bock beer (1.60 euros) in hand.
