Another great day trip from Mazatlán is a visit to Isla de la Piedra, known in English as Stone Island. A five-minute ferry ride away, this tranquil spot is actually a peninsula. It offers endless outdoor adventures — like horseback riding and some of the region’s nicest beaches. The restaurants here are also amazing, located in rustic palapas with views of the ocean. It’s typical to tip waiters 15% at restaurants, cafés and bars. Many big establishments accept credit cards, but it’s always good to have some pesos on hand.
