Although an otherwise unremarkable building, the beachfront condominium tower where infamous drug lord Joaquín "El Chapo" Guzmán was arrested in 2014 (he later escaped) has become somewhat of a tourist attraction, or at least a mildly-popular photo opportunity. You cannot enter the building.

Great Mazatlan Aquarium
Has bird, seal, and diving shows.
Mazatlan's hometown baseball team, the Venados, have been playing in Mexico's winter leageu (Liga Pacifica) since 1945, though the stadium itself dates from 1960. There's really not a bad seat in the house and prices are cheap (and so is the food and beer). If you're planning to go to a game, it might be better to take a bus or a taxi because there is no parking lot and street parking is tight.
Along the boardwalk you'll find the Fishermen's Memorial, better known as monkeys bichis; a bronze replica of a pulmonia taxi and a monument to the Pacific Brewery. This is great swimming and has a number of palm-roofed fish restaurants right on the beach. The southern end of this beach is dedicated to fishermen and their boats.
cemetery
There is a cemetery on Barragan, a block north of Najera. Beautiful and interesting.
El Clavadista
These daredevils do something similar as in Acapulco, but it is lower and more shallow. The rock formation that they climb up is about 13 m (45 feet) high and it is only 2-3 m (5-6 ft) deep. They wait for the right wave to make the dive. They are there all day long, but the best time to see them is in the morning.
at Hotel Playa Mazatlan, which is on monthly between November and March. Approach the concierge at the hotel there to book.
