Three days is the sweet spot for a first visit to Mazatlán. It is long enough to see the restored old town, spend real time on the water and sand, and climb to a view over the whole coast, but short enough that you never need to rush. The plan below gives each day a theme, keeps the walking in the cooler hours and leaves the evenings for the seafront and a long dinner. Treat it as a template: swap days around to suit the weather, and use the optional extras if you want a more active or more relaxed trip.
Day one: the old town
Start in the morning at the Cathedral Basilica of the Immaculate Conception, a nineteenth-century church that mixes neo-Gothic, Baroque and neoclassical styles. It is free to enter, so dress modestly and keep voices low. From there it is a short walk to the Pino Suárez Market, an iron-framed hall from 1899 where you can see produce, seafood and everyday life, and have a simple snack or a fresh juice. Take a break at midday, then return to Plazuela Machado in the afternoon, when the cafes and galleries around the square are at their best. If you like theatre, check what is on at the Teatro Ángela Peralta, since a performance in the restored hall is one of the most atmospheric evenings you can spend in the city. For a guided introduction to the stories behind the buildings, an Old Town Segway tour covers a lot of ground in a couple of hours, and the Barrio Bites food tour is a good alternative if you would rather taste your way through the neighbourhood. Finish with dinner on the plaza, where restaurants spread their tables across the paving.
Day two: water and sand
Take the morning boat to Isla de la Piedra, which is only a short crossing from the old town and has a wide beach lined with palapa restaurants. Plan on a late seafood lunch, a long swim and a slow afternoon, and carry some pesos for the boat and beach vendors, because not every stall accepts cards. If you would rather see more of the city, swap the beach for a Zona Dorada sightseeing tour, which connects the old town to the resort district, or a guided bike tour along the seafront, which covers far more ground than walking and keeps you in the breeze. Return in the late afternoon, rest, and take a taxi or a pulmonía to a seafront restaurant for dinner. Active travellers can add a half-day ATV adventure with lunch and a tequila tasting instead of the beach, then spend the evening quietly.
Day three: the hills and the view
Rise early for the hike to El Faro, the lighthouse on the Crestón hill, which stands about 157 metres above the sea and rewards you with a panorama of the coast. Allow about half an hour each way, wear shoes with good grip and carry water. Go before the sun is high, because there is little shade. After a late breakfast, visit the Observatorio 1873 and its whale museum for a calm indoor hour, with the sea views and the exhibits making a good contrast with the morning's climb. Spend the afternoon at your hotel pool or on the beach, then finish the trip with a sunset ride in a pulmonía, the open-air taxi that is a local tradition, followed by a walk along the Malecón and Olas Altas. The seafront is at its most beautiful when the sky turns orange, and it is a fitting way to end a stay.
Rainy-day and slow-day swaps
If the weather turns, move the aquarium, the museum and the market indoors, and keep the beach for a clearer day. The Gran Acuario in Parque Central is a good half day, especially with children, and the city sightseeing tour with lunch is a comfortable way to see the main sights from a vehicle. If you would rather not climb, replace El Faro with a long lunch and the bike or Segway tour. If you have a fourth day, spend it on a beach day in the Zona Dorada or add a second food experience.
Where to base yourself
For this plan, the old town makes the most sense, because day one is entirely on foot and the seafront is minutes away. Casa Lucila, Hotel La Siesta and Best Western Posada Freeman are all on or near Olas Altas, within walking distance of the plaza, and the Posada Freeman includes breakfast and parking. If you prefer a beach resort, you can still follow the plan by taxi, but allow time for the drive between the Zona Dorada and the old town.
Practical tips
The sun is strong at any time of year, so carry sunscreen, a hat and water. Book tours a day or two ahead in winter, check advisories for Mexico and Sinaloa before you travel, and confirm opening details for museums and the theatre before you go. Keep a little cash for markets, boat fares and small purchases, and plan your longest walks for the morning, when it is coolest.
