Olas Altas and Centro Histórico are two of Mazatlán’s most vibrant and historically rich areas, reflecting the city's blend of old-world charm and coastal beauty. Olas Altas, meaning "high waves," is the picturesque seafront promenade that stretches along the Pacific coastline. It is known for its stunning sunsets, lively atmosphere, and the rhythmic sound of waves crashing against the shore. Visitors here can stroll along the malecón, enjoy open-air restaurants, and experience the laid-back yet vibrant beach vibe that defines this part of Mazatlán. Olas Altas is also home to a number of historic hotels, like the Posada Freeman, which hark back to the golden age of Mexican tourism in the mid-20th century.

Just inland from Olas Altas is the Centro Histórico, the cultural and historical heart of Mazatlán. This district is filled with colonial-era architecture, colorful façades, and cobblestone streets. Landmarks like the Angela Peralta Theater, restored to its former glory, and the Plaza Machado are central to the area’s appeal, offering cultural events, live music, and a variety of dining options. The Centro Histórico is a hub for art galleries and artisan shops, and it reflects the city’s colonial heritage, making it a must-visit for those interested in Mexican history and architecture. The juxtaposition of the bustling streets and the tranquil plazas makes it a fascinating part of Mazatlán’s identity.
